Durable 93:7 TGIC Polyester Resin for High Gloss Powder Coatings for Aluminum Profile
◎Introduction
NH3307T is tribo chargerable version of NH3307, a saturated carboxyl polyester resin for polyester/TGIC powder coating system at the ratio 93/7.
NH3307 is our company’s star product. High Tg means high storage stability. It features excellent weathering resistance, so it could be durable for 5 years outdoors. With excellent leveling and anti-yellowing, it’s very suitable to make high gloss powder coatings for aluminum profile.
Models with a T indicate powder coatings made with this polyester resin that can be sprayed with a friction gun.
◎Basic Features
