Abstract: A chemical resistant powder coating composition comprising a urethane-polyester powder coating resin, a styrene-free hydroxyl functional acrylic resin, and a hardener. The composition may contain a flow aid that is a combination of a polyester hydroxyl resin, polyethylene resin, and spherical glass flakes and having introduced silica type carriers.
Abstract: A combination of polyester hydroxyl resin, polyethylene resin, and spherical glass flakes blended in conjunction with additional constituents such as polymeric curatives, degassing agents, blended and extruded as master batch and having introduced (3-aminoproply)trimethoxysilane and silica type carriers such as silicone dioxide at (45-55% active) reduces orange peel significantly.
