Dichloroethane
This composition is considered universal, as it has good contact with various types of materials and securely fixes them to each other. The composition is offered in the form of a clear liquid. But I want to note that it is not suitable for all types of metal. For example, it has poor contact with aluminum and enameled coatings. Accordingly, it is not used on the outer part of the car body, because even if it sticks plastic, it will not last there for long.
Gun glue
This composition is similarly used in various fields. Among the advantages are its sufficient elasticity and reliable fixation. This composition is sold in the form of flexible tubes with a diameter corresponding to the firebox of a hot-melt gun. You can even choose by shades. Although the adhesive composition reliably glues together parts of different structures, over time the seat becomes loose and, as a result, the glued fragments can lag behind each other at the most unexpected moment.

Some tips for choosing
- Find out the type of plastic from which the elements are made in order to choose the right adhesive.
- Be sure to read the markings on the packaging with glue: PP glues polypropylene, PE-polyethylene, PS-polystyrene, PC-polycarbonate, PVC-PVC.
- Always check the quality of the packaging and expiration date. The tube must be hermetically sealed and have the manufacturer's instructions and instructions.
- To repair children's toys, choose a solution based on the composition of BF glue.
- Buy packaging in a volume that you can use as quickly as possible. Even tightly sealed compounds dry out over time and lose their adhesive properties.
- When purchasing an adhesive component, take into account the properties of additional materials if you are gluing dissimilar elements to plastic.

Glue "Marathon"
A very reliable composition, but it is not capable of tightly gluing plastic to metal, especially if these parts are always subject to movement and vibration. It is often used to restore structures in the car interior, but the composition itself is intended for shoe repair. The adhesive mass has a characteristic, memorable odor. It disappears a couple of days after use, provided that the parts that were glued are well ventilated.

Dear masters, good day!
There is a need to glue a thermoplastic rose to the metal base of the ring. Any glue will not work, as you understand.
Tell me, please, who uses what adhesives for such cases?
There is one more problem - the base for the ring is not smooth, but with a pattern.
Thanks in advance for your answers!
But the almighty Poxypol - no?
Thank you Natasha! I read about Poxipol, it seems like it might be what I need.
Well, it's like a quick-setting epoxy. Used in jewelry. I glue laces into the ends and pearls onto the pin - tightly!
Super Moment Gel universal
any cyanoacrylate glue (I used cosmofen)
and it seems to me that any epoxy
something like that, please correct me if I said something wrong
This question is still interesting to me, because... There is no epoxy, and cosmofen is not available everywhere :))
Gel Moment I'm afraid. I tried gluing silver-plated wire with it, but it turned white all over.
I'll look and read about the rest, thanks!))
I didn’t glue it to precious metals, and nothing happened to me with ordinary metal fittings
there were different colors: copper, silver and yellow
Epoxy resin - 100% reliability.
There is an excellent German glue called U-hu. It glues everything to everything, is divided according to materials (fabric, wood, plastic, rubber, etc.), but there is also a universal one. It has been tested, metal glues to plastic, the mark is transparent, the tubes come in large and miniature. I only work with him.
Oh, I realized that you are talking about plastic, not plastic. I didn’t work with plastic surgery, unfortunately.
Cyanoacrylate glue
Its main task is to melt the plastic, which is subsequently well bonded to the metal. In this way, various attachments are often glued to thresholds, bumpers, fly deflectors and other parts. Polymerization of such glue occurs within 24 hours, but it can set almost instantly, so do not hesitate after applying the glue to the PVC part to be glued. Using such a composition, I once encountered a problem: when I had to update a plastic part, I removed the old one, but I could not remove the remains from the car body. Therefore, I advise you to glue it once and for all.

The best superglue for plastic
The most popular method for gluing broken parts or assembling miniature models is superglue. The name itself speaks of the extraordinary speed of gluing and high strength of the connection. Among the huge variety of small tubes, experts have identified several products.
4 Henkel Super Moment Maxi
Henkel Super Moment Maxi
Instant bonding of plastic and plastic is appreciated by professionals. Not every glue can cope with this task, but the Henkel Super Moment Maxi product is suitable for solving the most difficult problems. It not only sets quickly, but also firmly connects different materials. In addition to polymer parts, the composition can glue metal, cardboard, ceramics and porcelain. The manufacturer has made soft, convenient packaging and an elongated tube spout. This made it possible to apply glue accurately and economically, without the craftsman’s hands being in the solution. The cap is easy to remove, and when closed it prevents air from getting inside the tube.
Experts note the instant setting of superglue, reasonable price and convenient bottle. The product qualitatively combines a wide range of materials, which attracts the attention of professionals. The disadvantage of the product is that it is of Russian origin, which is why its quality is not always stable.
3 Superglue POWER
Superglue POWER
High-quality superglue SILA is sold on the domestic market at an affordable price. At the same time, the composition firmly glues plastic, plastic, porcelain, glass, leather and wood. Thanks to the convenient tube, the required amount of glue can be accurately applied to the surface of the part. This has a positive effect on consumption. Experts note that there is no spreading; the gel does not drip onto other objects or hands. The basis of the product is ethyl cyanoacrylate, to which thickeners are added. After drying, the adhesive seam becomes transparent, which is important when gluing white or colored materials. The strength of the connection during testing was 175 N.
Users speak flatteringly about the effectiveness of the glue, affordable price, and ease of use. The glue does not have a strong odor and sets within a few seconds. Among the disadvantages, consumers note the insufficient thickness of the gel, as well as the presence of a large number of fakes on the market.
2 Economy Express Universal
Economy Express Universal
Chinese superglue Econ Express Universal has instant action. It is easy to use, sets quickly, and is unpretentious in work. The composition is suitable for gluing plastic and plastic, metal and paper, rubber and porcelain. Experts note the high strength of the adhesive joint; it can withstand a load of 210 N. The use of glue is quite standard, the surface of the parts is cleaned and degreased, applied to one of the parts, and the compression time is 5-60 s.
Users note the low price of the composition, good quality and reliable seam. Even under the influence of water, the glued parts do not separate. Consumers also respond positively to the sealed cap, through which air does not penetrate inside. The disadvantages include a pungent odor, which can give you a headache when working in a small, unventilated room.
1 Permatex Super Glue
Permatex Super Glue
Superglue Permatex Super Glue with a gel-like consistency is characterized by high bonding strength to plastic. During comparative tests, experts from the magazine “Behind the Wheel” recognized it as the winner. The destruction of the adhesive seam occurs under a load of 245 N, which significantly exceeds the performance of competitors. It is also noted that the glue is convenient to use when it is necessary to glue thin parts. The product is recommended for gluing hard-to-reach and vertical surfaces. High bond strength is observed on non-porous plastics.
Users are satisfied with the adhesive strength, speed of setting and ease of use. The seam turns out transparent, and in addition to plastic and resin, you can work with metal, rubber and ceramics. The product is economical in consumption, per 6 sq. cm of surface, one drop of the composition is enough.
General recommendations for gluing metal and plastic
In this small section I want to talk about some of the nuances in the question of how to glue plastic to metal. Regardless of the type of glue chosen, all tips will be the same:
- Before gluing two pieces together, make sure each piece is perfectly washed and clean.
- Then take a cotton pad and apply a degreaser to it: it can be white spirit, acetone, or regular alcohol.
- Then, use the same disk to wipe the areas that will be glued. Leave until completely dry.
- Apply the selected adhesive composition to the prepared plastic surface and attach the parts to each other and hold for a few seconds.
Afterwards, leave the glued plastic and iron for a day so that the connection sets and becomes more reliable.
This video provides a list of materials, including iron and plastic, that can be glued together with just one type of glue
The best waterproof glue for plastic
Plastic products perfectly withstand exposure to moisture for a long time. To ensure the assembly remains waterproof, it is important to select the appropriate adhesive. The following formulations boast good reviews.
4 Cosmofen Plus-S
Cosmofen Plus-S
Modern plumbing systems use many plastic elements, from polypropylene pipes to plastic gutters. Cosmofen Plus-S glue copes well with these and many other polymer materials. The product is often called liquid plastic and is white in color. Due to its water resistance, inertness to alcohol and petroleum products, the adhesive composition is suitable for installing pipelines, constructing advertising billboards, and creating plastic windows and doors. The adhesive joint not only withstands exposure to precipitation, but also exhibits exceptional resistance to ultraviolet radiation and withstands temperature changes.
Users in reviews note the affordable price of liquid plastic, quick drying, plasticity of the seam, and resistance to various atmospheric influences. The disadvantage of glue is its strong, toxic odor.
3 88 Luxe
88 Luxe
When you have to glue large areas (along the contacting surface), you should pay attention to 88 Luxe glue. This brand has long been known in our country; today the product is produced by different manufacturers. Among the main advantages of the composition, it is necessary to highlight the affordable price and high efficiency of the adhesive joint. Using a viscous solution, you can connect different materials, from plastic, plastic and ending with rubber. Often a jar with the inscription 88 can be found in shoe workshops where a wide range of polymers are used. After complete drying, the seam withstands strength and water resistance tests.
There are many positive reviews from users, mentioning properties such as availability and quality. Disadvantages include long drying times and an unpleasant odor.
2 Loctite 406
Loctite 406
Fast-acting waterproof adhesives for plastic include Loctite 406. Its uniqueness lies in its high bonding strength on both rough and glossy surfaces. These can be plastics, elastomers, metal or rubber. Experts note the low viscosity of the product, the absence of a gap when connecting parts, and the high polymerization rate. Using the glue is quite simple; the surfaces are cleaned and degreased, after which the solution is applied. The temperature resistance of the seam is in a wide range (-40…+80ºС). The glue retains its properties even when exposed to moisture.
Users like the speed and ease of gluing, reliable fixation, and instant grip. The disadvantages of glue include its high price and unpleasant odor. Consumers also complain that the composition does not tightly connect all types of plastic.
1 Moment Plastic
Moment Plastic
One of the best contact types of glue for plastic is Moment Plastic. It is perfect for various polymer materials, be it plastic or polyethylene. A distinctive feature of the product, according to experts, is the fast drying time. Even under the influence of water, high strength is maintained. The adhesive joint is not afraid of sudden temperature changes. The composition is inert to aggressive chemicals of inorganic origin (acids, alkalis, salts). The advantages of the glue include the transparency of the solution, which significantly expands the scope of application.
The composition is in steady demand among domestic consumers, as evidenced by Wordstat statistics. It is affordable, gluing plastic is simple and reliable. But the composition contains compounds hazardous to human health, so contact of the glue with skin or food is not allowed.
How to remove glue from a car body
The difficulty of removal lies in the damage to the paint surface of the body from exposure to the solvent. You can try to soften the stain with water or soapy water, but this is an ineffective method.
Experts advise removing glue from the car body using the pharmaceutical product “Dioxide”. The product is not toxic, but it is recommended to work in a well-ventilated area. The process is long and painstaking. Dip a cotton swab into the product and wet the top layer. After 2-3 minutes it will get wet, remove the top layer with another stick.
Remove layer by layer - you will get rid of the hated stain.
Read our article on how to remove tinting adhesive from car glass:.
Hot melt adhesive
A special composition that is capable of connecting plastic elements. Supplied in rod form. The distinctive features here are as follows:
- gluing is possible only in case of strong heating;
- A special gun is required for operation.
Basically, such a product is used for creativity, since the strength of the finished items is not too high, as a result of which the repaired products will not serve for a long period.
The choice of a specific model is influenced by the dimensions of the rod, the level of transparency of the substance, viscosity, operating temperature, etc.
What glue is best for gluing plastic to plastic?
Until now, we have considered compositions for repair bonding of parts. But when working at home, you may need to connect two plastic surfaces or joints. If the plastics are homogeneous, the adhesive composition can be selected according to the described criteria. When choosing which glue is best for gluing smooth plastic to porous plastic, do not pass by the Ukrainian brand Elite Drakon.
Dnepropetrovsk produces universal adhesive for gluing expanded polystyrene and foam glass to smooth plastics and polymer floor coverings. The elastic adhesive layer is waterproof and frost-resistant, suitable for interior and exterior use. Cosmofen CA 12 cyanoacrylate adhesive is well suited for gluing together smooth planes made of polycarbonate, polyvinyl chloride, and plexiglass.
The second representative of the products of the German company Weiss is distinguished by a short setting time (3 seconds) and completely hardens in 12 hours. This glue can be used to glue plastics to glass, metal, and ceramics. The tensile strength of the adhesive is low, so it is used for temporary connections, advertising, and artistic works. If you need to firmly connect the corners of a plastic box, extrusion and injection sheets, glue the frame of an aquarium, glue three-dimensional acrylic letters to the wall - look for the little-known adhesives Altuglas P12 or Altuglas P10. Both adhesives are versatile and durable.
The composition of the three-component Altuglas P12 adhesive was developed by the American company. A significant disadvantage of the glue is the toxicity of the two components (toxicity of the vapors) and easy flammability. You need to work with glue wearing safety glasses and gloves, at room temperature. Altuglas P10 two-component adhesive is less dangerous.
Let's sum it up
If you decide to repair plastic elements in your vehicle, then you should purchase the best plastic adhesive possible. At the moment, you can buy quite a lot of different compositions on the market, so you should carefully familiarize yourself with the operating features of a particular model.

At the same time, you should not choose too cheap models, as well as products from little-known brands, since their quality often leaves much to be desired. It should be taken into account that most products are extremely ineffective, so it is better to overpay a little than to then run to the store for a new composition.
Next is a video about quick glue for plastic:
Cold welding
The peculiarity of this type of glue is that it includes two components and, after mixing, turns into a practically indestructible composition. The best option is to securely glue the plastic.
Aviora Monolith 403-218 45 g
This two-part epoxy adhesive is an excellent option for bonding a variety of materials, as well as for filling cracks or holes. It is not afraid of high temperatures, sets quickly and is very economical. The finished composition has good viscosity, so it is convenient to apply it to the gluing site or as plaster. After hardening, it turns into a durable material that is not afraid even of mechanical stress.
Advantages:
- cheap;
- good viscosity;
- easy to use;
- very durable after polymerization;
- not afraid of moisture;
- not afraid of high temperatures.
Flaws:
- missing.
Cold welding adhesive Poxipol 10 minutes transparent 00269 0.07l
Cold welding from Uruguay with two components that must be mixed before use. Among the advantages of the composition is resistance to water and chemical influences. Can be used at temperatures up to 120 degrees, sets in 10 minutes. It can bond plastic, glass, concrete, porcelain, stone and wood.
Advantages:
- fast adhesion;
- transparent;
- easily grasped even by perfectly flat objects;
- mixes easily;
- resistant to shock loads.
Flaws:
- sometimes there are fakes in which the composition turns out yellow;
- high price.
What affects the reliability of gluing
Not many people know that adhesion strength depends on many factors. To avoid mistakes, you need to follow some rules. There are several conditions for successful gluing:
- Selection of adhesive suitable for a specific plastic;
- The compression and hardening times must be observed;
- Prepare the surface, remove dirt, degrease and smooth. The parts must be immediately pressed into the correct position.
To avoid mistakes, you need to follow some rules.
Rexant Dichloroethane
Volume : 30 ml.
Price : 87 rub.
If you need to glue the temples of glasses or glue other small plastic parts, Rexant Dichloroethane . This glue is so highly diluted that the smell of dichloroethane is practically absent. One of the buyers shared that he used glue for gluing PLA - it did the job perfectly.
The glue dries quickly and grips the plastic well; in addition, while it hardens, you can adjust the parts. Rexant Dichloroethane connection is reliable (which is exactly what we need), the main thing is not to rush to use the glued parts - let the glue dry completely.
For reference: the glue looks like water, but don't be afraid - it glues perfectly!
Features of such substances
Plastic is a fairly durable substance, but at the same time, such a material practically cannot be glued due to low adhesion and chemical reactivity.
In addition, there are no small pores on the surface. Thus, special compounds should be used to repair such elements.
There is another way to repair plastic - welding. At the same time, such a solution is only suitable for service in special workshops; this method will not be relevant in everyday life, so all that remains is to buy glue or completely replace the item.
Hosch
The cost here is quite high, but the efficiency is decent. At the same time, this two-component plastic adhesive performs well on both smooth and rough surfaces.
To increase gluing parameters, flux powder should be used.
True, the tube is very small, and applying the composition on an inclined plane is very difficult, since the powder will simply crumble.
Features of gluing plastic in cars
Automotive plastic can be glued by welding and using glue. The welding method is only suitable for thermoplastics that can withstand high temperatures.
Pasting plastic parts with an adhesive composition is universal. Amateur motorists can handle it.
When gluing plastic parts, take into account the markings of the plastic (manufacturers put its number on the reverse side). The glue is selected taking into account the markings; follow the instructions from the manufacturer.
Stages of surface gluing work:
- Lightly sand the top layer of the surface with sandpaper for better adhesion of the materials.
- Degrease with alcohol.
- Apply an even layer of glue to the surfaces to be glued.
- Depending on the base of the adhesive composition, either immediately press firmly for a few seconds, or let it stand for 10–15 minutes, then glue.
We invite you to watch a video about glue for plastic:
When fixing plastics, glue should be selected taking into account the nature and purpose of the work:
- to glue the fragments, select a fixative that melts plastic, for example, Permatex 84115;
- cracks, tears, ideally fills seams - based on cyanoacrylate;
- large surfaces - epoxy adhesive with additional reinforcing structures.

Liqui Moly
This German manufacturer is one of the most popular manufacturers of vehicle consumables. The glue perfectly connects rough overlapping elements. The dispenser is very convenient to use, and the composition itself dries quickly.
The instructions precisely describe what precautions must be taken when working with the substance. The disadvantage is that it is not very durable.
ABRO Super Glue
The production is carried out by the world famous American brand ABRO. The cost is one of the lowest (you can buy it for just a couple of tens of rubles), however, that’s where the advantages end.
The quality is very low, the instructions in Russian are very unclear. It may be suitable for small elements, but it is not recommended to glue anything important with ABRO Super Glue.
Cosmofen CA 12
Another product from America, but this time the price is in the middle price range. The bottle is distinguished by its ergonomic shape and fairly large volume.
The instructions are clear, there is a translation into Russian. On the other hand, the gluing performance here is very mediocre, and even after use there is some glue left on the cap.
How to achieve maximum effect when gluing plastic parts
To achieve the best result, you should study the recommendations of specialists. They highlight the following points:
- The need to correctly determine the type of plastic;
- Strict adherence to manufacturer's instructions;
- it is necessary to maintain the specified time until the gluing process is completed;
- If there are no marks, you can apply glue to an inconspicuous area and see the reaction of the material.
it is necessary to maintain the specified time until the gluing process is completed.
3M Scotch-Weld
The composition is produced in England. Its advantages include a large packaging volume, ease of operation, as well as excellent adhesion performance in the case of glossy surfaces. However, if the edges are rough, the effectiveness is greatly reduced.
Another disadvantage is that the glue in the dispenser hardens very quickly. The cost here is quite high, this should also be regarded as a disadvantage.
