saturated polyester resin for coil coating

Detailed Product Description

 

Polyester resin usefull and function detailed information

Saturated  polyester resin is it mainly used in Coil Coating

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.

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.

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.
