Aluminium powder paint

Mainly made of polyester resin and curing agent, leveling agent, pigment, filler and other addictives. Also call weatherability powder coating or outdoor type powder coating. These coatings have good edge coverage and good mechanical properties. These coatings are known for their good UV resistance as compared to epoxy, epoxy – polyesters. Polyester powder coatings are used widely for industrial finishing and typical applications include office furniture and aluminium extrusions, automotive wheels, lawn furniture, and air conditioner cabinets.
