Powder Paint Polyester resin NH3309C Excellent flow enhanced outdoor durability
NH3309C is a saturated carboxyl polyester resin for a polyester/TGIC powder coating system with excellent levelling. It is also suitable to mix with acrylic or matting agent to produce low gloss or matt powder coatings.
With the continuous development of powder coatings, people have higher and higher requirements for the gloss of coatings. In some specific environments, it is necessary to use coatings with low gloss and soft light. Therefore, the demand for low-gloss or matt powder coatings becomes more and more.
