Powder CoatingThe surface properties and smooth texture provided by the sanding agent enhance the coating's performance against scratches, adhesion, wear, and improve sliding properties and resistance to metal streaks, significantly boosting its water and waterproof capabilities. When used in conjunction with aerogel silicon dioxide and organic montmorillonite, it can address their shortcomings in providing poor surface properties to the film. Additionally, it can optimize the arrangement of matte powder on the coating surface, allowing the coating's matte birefringence properties to function better.
