Saturated Polyester Resins, 84/16 Isocyanate Polyester Resin for Powder Coatings

◎Introduction

NH7809 is a hydroxylated polyester resin for polyester/isocyanate powder coating system.

Powder coatings made of hydroxy polyester resins are also known as super durable powder coatings because of their excellent weather resistance and outdoor durability.

With the continuous development of the national economy and the continuous improvement of people's living standards, the requirements for the decoration, weather resistance, chemical resistance, water resistance and fouling resistance of coatings are getting higher and higher. Therefore, the demand for super durable powder coatings is increasing day by day.

◎Basic Features

Excellent leveling

Excellent outdoor durability

Good mechanical properties

Good chemical resistance
