Advantages:
(1)Can reduce the gloss of PES/TGIC powder coating to 30%(60 ) without significantly damaging to the weather-resistance ,flow and mechanical properties. The moderate gloss coatings usually are application to lighting fixture, appliances, air conditioner and office partitions and automobile parts.
(2)Be enable to use in other coating systems such as pure epoxy and epoxy/polyester hybrid to provide these systems with semi-gloss, smooth appearance and good non-yellowing properties.
(3)This product belongs to adding type-matting agent without taking part in chemical reactions; thus the special design for coating formulation is unnecessary. You are only selective for adding it at the premix stage of powder coatings. Varying its added amount or selecting proper filler can adjust the gloss levels of the resultant coating, but the variable ranges usually are limited.
(4)May be as a modifier to improving coating surface hardness and anti-mar properties when desired at less than 1.0% based on total formulation.
