Product Description

High Cost-performance HAA Polyester Resin for Sand and Wrinkle Powder Coatings
NH0305 is a high cost-performance saturated carboxyl polyester resin designed for both TGIC and HAA powder coating systems, especially for sand and wrinkle powder coatings. But it features weak weather resistance, only recommend to produce indoor use powder.
The surface treatment of aluminum profiles has always been the main application field of powder coatings; at the same time, the application of powder coatings on aluminum profiles has also made the surface colors and touches of aluminum profiles more and more diverse, and the sand-grained surface is the main representative of the application effect of powder coatings, and more and more popular with consumers.
Thermosetting sand grain powder coatings not only have many advantages of general thermosetting powder coatings, but also have beautiful patterns and strong decorative properties. They can also make up and cover defects such as rough and uneven surfaces of workpieces.
