93/7 Saturated TGIC Polyester Resin With Good Blooming Resistance
◎Introduction
NH3396 is a saturated carboxyl polyester resin for polyester/TGIC
powder coating system.
Powder coatings have the characteristics of solvent-free, simple
construction, high utilization rate, and are growing rapidly in the
global market. Matting powders have good decorative properties, and
are the most widely used powder coatings for indoor decoration.
When the paint film is tested at 60 ° angle, the gloss above 90% is
called high gloss, 60-90% is called flat gloss, 20-60% is called
matte, and the gloss below 20% is called low gloss. The market
demand for matting powder coatings is also growing. There are many
ways to reduce the gloss, and the common way is to rely on the
system of physical matting agent or semi chemical matting agent.
As a commonly used additive for powder coatings, matting agent is
often very expensive. For products with the same gloss effect,
polyester itself has a good extinction, which can determine the
final cost performance ratio of the product.
◎Basic Features
Good blooming resistance.
Good outdoor durability.
Good flow
