China Paint Online News: Unsaturated Polyester Resin - Chinese Name: Unsaturated Polyester Resin; Definition: Wire polyester resin with carbon double bond in the main chain. It can be composed of unsaturated binary carpentry (or acidic acid), saturated binary pythonic acid (or acidic acid) and binary alcohol (generally saturated binary alcohol), and ethylene monomer can form a mesh structure of the material. Applied disciplines: material science and technology (first-level discipline), polymer materials (second-level discipline), plastic (third-level discipline) above the content by the National Science and Technology Noun Review Committee for the review and publication. Unsaturated polyester resin unsaturated polyester resin, generally composed of unsaturated binary acid binary alcohols or saturated binary acid unsaturated binary alcohols, with ester bonds and unsaturated double bonds of line polymer compounds. Typically, polyester shrink reactions are performed at 190 to 220 degrees C until the desired acid value (or viscosity) is reached, and after the polyester shrink reaction is over, a certain amount of vinyl monomer is added to the heat and added to the viscous liquid, which is called unsaturated polyester resin. Unsaturated polyester resin is the most commonly used in thermostered resin, it is a line-shaped polymer composed of saturated binary acid, unsaturated binary acid and binary alcohol, diluted by cross-linked monomer or active solvent formed with a certain viscosity resin solution;3.2, coating performance test model preparation and coating film performance test
