Cellulose acetate butyrate, short name CAB, has a wide range of applications in the coating industry and has its uniqueness, which is difficult to replace by other chemicals; in the automotive and furniture industries, it has excellent weather resistance and UV resistance Bow; CAB varnish does not turn yellow and does not crack in cold weather. It has excellent flexibility in leather coatings; in the ink is putty, it has excellent miscibility with other resins, leveling and anti-running. In aluminum. copper. CAB is added to silver and other metal coatings. Can accelerate the release of solvents from the paint film. The time to touch dry can be greatly shortened. In thermoplastic acrylic air-dry paint coatings. This performance is more prominent. Because CAB contains hydroxyl groups. It can react with amino resins in the presence of acid catalysts. It does not affect its own hardness but also imparts flexibility to the coating film. And this varnish has good adhesion. Make the coating have a very high gloss. Adding CAB to the coating can enhance abrasion resistance. Color stability. And make the car paint bright and beautiful. Improve the cold crack resistance of leather and so on.
