(Summary description)Unsaturated polyester resins are generally linear polymer chemical substances with ester bonds and unsaturated double bonds formed by polycondensation of unsaturated dibasic acid diols or saturated dibasic acid unsaturated diols. Generally, the polyesterification polyaddition reaction is carried out at 190-220°C until the estimated acid value (or viscosity) is achieved. After the polyesterification polyaddition reaction is completed, add some vinyl monomer while it is hot. Formulated with thick solvents, such polymer solvents are called unsaturated polyester resins.

Information

Unsaturated polyester resins are generally linear polymer chemical substances with ester bonds and unsaturated double bonds formed by polycondensation of unsaturated dibasic acid diols or saturated dibasic acid unsaturated diols. Generally, the polyesterification polyaddition reaction is carried out at 190-220°C until the estimated acid value (or viscosity) is achieved. After the polyesterification polyaddition reaction is completed, add some vinyl monomer while it is hot. Formulated with thick solvents, such polymer solvents are called unsaturated polyester resins.

1. There are no volatile by-products when dry and solid, basically reaching 100% dry solid   

2. Fast drying, even at room temperature, it can be dried   

3. Unsaturated polyester resin can be dried in various forms, such as peroxide, ultraviolet light, radiation, etc.

4. Unsaturated polyester resin can be molded at low voltage and touched pressure molding

5. Good mechanical equipment and electrical performance

6. Unsaturated polyester resin has good drug resistance and quality

7. It can give flexibility, rigidity, weather resistance, temperature resistance, drug resistance, thixotropy, non-combustibility, self-extinguishing and other characteristics

8. It can be colored to get a fully transparent, beautiful and generous coating

9. It can complete the coating process that takes into account maintenance and decoration design

10. Exothermic reaction when dry and solid, which increases the ambient temperature, which can be used in cold pressing molds
