Powder Paint Polyester resin with Dry-blended for 25-40% Gloss
◇ Applications:
NH8001/NH8505 are saturated carboxyl polyester resins for low gloss polyester/TGIC powder coatings by a dry blend procedure.
The balance between high leveling, high weather resistance and mechanical properties of powder coating was solved through the design of product molecular structure, the screening of monomers and additives and the study of synthesis kinetics;
In this model, we upgraded the formula to achieve the balance between high leveling, weather resistance and mechanical properties of powder coatings.

Good leveling
Excellent mechanical properties
Good storage stability
Good chemical resistance and fine anti-yellowing
Good weathering resistance
