Tin-free Hybrid Polyester Epoxy Resin with Excellent Extinction Performance
◎Introduction
HH2583A is a saturated polyester resin, the tin-free version of HH2583. Mainly used for 50/50 polyester/epoxy hybrid powder coatings systems.
Models with an A indicate that this polyester resin is tin-free, which is mainly prepared by using tin-free catalysts.
As a new type of environment-friendly coating, powder coating has become the most promising coating in the world due to its excellent characteristics. With the continuous improvement of people's living standards and changes in aesthetics, the amount of low-gloss powder coatings shows a larger upward trend; high-end matt coatings, with their naturalness, nobility and elegance, attract consumers. The surface can conceal minor paint film defects, making the appearance uniform and more user-friendly.
HH2583A features excellent extinction performance, ideal for making low gloss powder coatings.
◎Basic Features
Excellent extinction performance
Good mechanical properties and storage stability
Not recommended for the preparation of high gloss powder coatings
