Detailed Product Description
Polyester resin usefull and function detailed information
I: the introduction of saturated polyester resin
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.
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.
