99.99% purity Nano aluminium oxide polishing al2o3 powder

Specification of polishing al2o3 powder:

polishing al2o3 powder is used in powder coatings to improve the bulkiness of powder coatings and has 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-alumina can improve the charging performance of the powder, especially when using triboelectric spraying, it can significantly improve the powder loading rate and solve the problem of dead angle, and has no effect on the gloss of the powder coating.

Application of polishing al2o3 powder:

1. Thermosetting powder coating: epoxy resin, polyester, acrylic resin.
Examples of epoxy powder coatings, polyester powder coatings, acrylate powder coatings, etc.
2. Thermoplastic powder coatings: Thermoplastic powder coatings include: polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide, cellulose, polyester. Examples of polyvinyl chloride powder coating, polyethylene powder coating, nylon powder coating, fluororesin powder coating, latex powder coating, etc.

Storage conditions:
polishing al2o3 powder should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
