Coating classification: Terminology of automotive coatings

Key tips: key terms of automotive coatings: 1 Primer Automobile primer is the paint used before spraying the top coat It has four main functions: preventing metal surface from rusting; filling property; providing good adhesion to the second coat of primer and top coat; isolating the influence of old paint layer or primer on the top coat, avoiding "absorption" phenomenon and reducing the gloss of the top coat Classification: plastic primer, phosphating primer, epoxy primer, suhuishi, intermediate primer, filling primer, etc 2 top coat Generally speaking, there are two types of car finish: plain paint Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Home of coatings: key terms of automotive coatings: 1 Primer automotive primer is the paint used before spraying the top coat It has four main functions: to prevent metal surface from rusting; to make filling properties; to provide good adhesion to the second coat of primer and top coat; to isolate the impact of old paint or primer on the surface paint, to avoid "absorption" phenomenon and reduce the gloss of the top coat Classification: plastic primer, phosphating primer, epoxy primer, suhuishi, intermediate primer, filling primer, etc 2 Generally speaking, there are two types of automobile top coat: plain color paint and metallic paint Metallic paint is divided into: silver powder paint and pearl paint Varnish is mainly sprayed on the top of single component topcoat to provide protection, weather resistance and luster, and play the role of decoration and protection of the underlying topcoat They are also called gold oil, clear oil and bright oil 4 curing agent is generally used in 2K solid paint and varnish According to the concentration, it can be divided into high concentration, standard concentration and low concentration According to drying speed: super fast drying, fast drying, standard, slow drying and other types The main function of diluent is to reduce the viscosity of paint, in order to obtain a better spraying effect and increase the smoothness of paint film Generally, according to the drying speed, it can be divided into five types: super fast drying, fast drying, standard, slow drying, super slow drying and so on It is also called interface water or interface varnish It is specially used to desalinate the "mandarin duck" color difference at the interface of the new and old paint films of pure paint, so that the new and old paint films can be dissolved into one, and the repair effect can be more perfect It does not need to be diluted It can be directly applied 7 White water is mainly used to prolong the drying time of the paint, improve the leveling of the paint at high temperature, and reduce the "whitening" phenomenon caused by spraying when the humidity is too high Depainting water is a kind of highly corrosive solvent, which has strong dissolving and corrosive power and can remove old paint film Generally directly brush on the surface of the old paint to be removed 9 degreaser is generally used to clean impurities and oil stains on the surface of substrate, improve the adhesion and anti rust ability of finish paint, and reduce the generation of fisheye It is used for thorough oil removal 10 blending varnish is also called blending resin, which is generally divided into two types: metal and plain paint; plain paint blending resin, mainly to improve the gloss of two-component paint surface Metal paint blending resin is mainly used to improve the adhesion of silver powder or pearl, improve the directional arrangement of silver powder or pearl, and reduce the occurrence of floating color and blooming The color control agent is mainly used in silver powder and pearl paint to make the front side of the metal gray and white; to make the silver powder loose and the particles coarser; to enhance the metal flash effect of the side; to reduce the front glossiness; to speed up the air drying However, it should be noted that the use amount of color control agent should not be too much, which will affect the covering power of the top coat 12 plastic primer is mainly sprayed on the surface of plastic parts to improve the adhesion of top coat The softener is mainly added to two-component finish or varnish to make the film sprayed on plastic parts soft and not easy to crack and crack 14 matte agent reduces the gloss of 2K finish or varnish until it is Matt It can accelerate the drying speed of paint film Also known as matte resin, light reducer Red grey one component filling agent, used to fill the surface scratches, sand holes and small sandpaper fine lines of high-end cars, automobiles and commercial vehicles 16 atom ash two-component, soft solid filling material, can be solidified at room temperature, used to fill the sunken parts of automobile maintenance 17 atomic ash is a kind of primer, which is generally one component of nitro group Fill in small marks and slight dents after sanding, and provide simple isolation Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
