polyester resin for coating

Detailed Product Description

 

Polyester resin usefull and function detailed information

The resin  is a multi-acid and polyol formed the polymerization of the polymer, and then dissolved in organic solvents and form uniform transparent viscous liquid . Resin formulations of the system of adjustment can be straight-chain and branched-chain-type models, and other resins.

To meet the needs of a variety of molding products processing performance and the requirements of different uses.

The polyester resin also for base  paint, back paint, top paint, three kinds of paint common. Paint made of polyester resin with a weather resistance, high around the song, anti-scratch and solvent resistance. Surface quality, appearance, Paul Light, color retention, adhesion, anti-bending, anti-peeling, resistance to humidity, salt fog performance. And the film can withstand a direct cutting, bending, deep drawing, meshing, etc. machining.
