Although there are not many varieties of coating process glue, it is the most used type in automobiles.
Bicycle consumption: about 2kg for trucks, and more than 5kg for cars. There are mainly weld sealants and stone-resistant coatings. The substrate components are all PVC plastisols. Although both have their own focus on performance, they both require high-pressure coating equipment to implement mechanized coating or spraying. Comparison:
(1) The weld seam sealant has more prominent thixotropy, and it can keep the edges and corners when it is piled up to a certain thickness and does not flow. After heating and plasticizing, the adhesive layer is elastic, does not crack, and has a smooth appearance. The middle coat and top coat cannot change color. Weld sealant plays a vital role in automobile sealing, leak prevention and rust prevention.
(2) The anti-stone impact coating is sprayed on the chassis of the car to buffer the impact of various objects such as sand and stones on the chassis when the car is driving at high speed, improve the corrosion resistance of the chassis, extend the service life, and also help reduce the noise in the car. Improve the comfort of occupants.
