Although there are not many varieties of glue for the coating process, it is the largest type of car.

Usually bicycle usage: about 2kg for trucks and more than 5kg for cars. There are mainly weld sealant and stone-resistant paint, all of which are PVC plastisol. Although both of them have different performances, it is required in the process to be capable of mechanized coating or spraying by high-pressure coating equipment.

Interior parts with glue

Automotive interior parts are available in a wide variety of materials, properties, and applications. Therefore, there are still some differences in the use of rubber varieties, it is difficult to generalize. Xiaobian introduces some of the varieties:

Body roof glue

It is used to attach the soft ceiling material to the roof of the car to enhance the interior aesthetics. At present, the adhesives for this purpose in China are mostly solvent-based neoprene. The process and performance require high initial adhesion, meet the fast-paced needs of the body interior production line, and avoid the occurrence of discoloration and shedding of interior materials. .

Butyl sealing tape


It is extruded into a belt type by adding a tackifying resin to butyl rubber. Its characteristics are: easy to fit, good adhesion to steel plates and waterproofing membranes, and long-term retention of elasticity and sealing. It is mainly used for the adhesive sealing of the waterproof membrane of the inner panel of the door to prevent rainwater from penetrating into the interior. Usually, the amount of single door tape on a car is about 2m.

High frequency heat sealing glue

The high-frequency heat-sealing adhesive for vehicles is modified acrylic. When the inner panel of the door is formed, the pre-impregnated fiberboard is melted in a short time under the action of high-frequency electric field, and PVC foam is produced under the pressure specified by the process. Produces a strong bond.

Windshield glue

These kinds of adhesives are usually made of polyurethane. They are used together with cleaning agent and lacquer/glass primer. The shear strength is high and the elasticity is outstanding. The glass and the body can be tightly combined into one whole, which enhances the rigidity of the body and ensures the sealing effect. Improve car safety, usually around 1.2kg.


Assembly glue


Automobile engine, gearbox, chassis assembly adhesive, sealant, its application is mainly reflected in various flat connections, the sealing of the hole cover pipe joint and the bolt locking, which can prevent the leakage of oil, water and gas and the looseness of the bolt. This is directly related to the normal safe driving of the car. The main varieties of such adhesives are: anaerobic adhesives, silicone sealants and the like.

Anaerobic adhesive

The utility model has the advantages of simple coating process, fast curing speed and good sealing and sealing performance. In the use, acording to different requirements, on-site coating, pre-coating and soaking can be adopted.

Silicone sealant

This kind of adhesive is unique for flat sealing. It has good elasticity, oil resistance, heat resistance, aging resistance, simple rubber coating process, strong strippability and easy disassembly. It can replace the gasket and use it alone.
