Product Description

Excellent Leveling TGIC Polyester Resin for Matte Powder Coatings
NH3407 is a saturated carboxyl polyester resin for the polyester/TGIC powder coating system. It features excellent impact resistance, excellent extinction performance, and excellent leveling, suitable for matte powder coatings.
Film gloss (%) is an important index for powder coatings. Glossiness refers to the ability of the surface of an object to reflect light when the light is reflected on the surface of the object.
In the past, the high-gloss bright powder coating was favored by consumers because of its bright color and brightness. However, with the continuous improvement of people's living standards, consumers felt that the reflection of high-gloss bright powder coating was more serious after film formation, which was harmful to the eyes people; at this time, the high-grade matt powder coating, with its natural, noble, elegant and other characteristics, has attracted the majority of consumers.
Due to its excellent extinction performance, the TGIC polyester resin NH3407 is very suitable for matt powder coatings.
