2. Thermoplastic powder coatings: Thermoplastic powder coatings include: polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide, cellulose, and polyester. Examples: PVC powder coatings, polyethylene powder coatings, nylon powder coatings, fluororesin powder coatings, latex powder coatings, etc.
Nano aluminum oxide (model VK-L20M) is used in powder coatings to increase the bulkiness of powder coatings and has a good anti-caking effect. It has good storage properties for powder coatings used in high temperature and high humidity environments. The addition amount is generally 0.3-0.5%, and the effect is better when the finished product is sieved. Nano-aluminum oxide can improve the charging performance of the powder, especially when using friction charging spraying, it can significantly increase the powder loading rate and solve the problem of dead corners, and it has no effect on the gloss of the powder coating.
The recommended dosage is 0.3-0.5%, and the user should determine the dosage according to different systems after testing.
