saturated polyester resin for finishing coat

Detailed Product Description

 

Polyester resin usefull and function detailed information

. Rolled steel is currently manufacturing more than paint to the paint-based unsaturated polyester resin.

Saturated polyester resin  apply primer, back paint, paint, paint three.Made with its paint with weatherability and a high around the song, anti-scratch and solvent resistance.

The resin is a multi-acid and polyol generated by 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.
