Title:
POLYESTER RESIN FOR METAL POWDER COATING, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/082179
Kind Code:
A1
Abstract:
The present invention provides a polyester resin for a metal powder coating, and a preparation method therefor and an application thereof. The polyester resin for the metal powder coating is prepared from the following raw materials: polyol, halogenated bisphenol A, terephthalic acid, phthalic anhydride, an acidolysis agent, and tertiary glycidyl carbonate. The polyester resin for the metal powder coating of the present invention, by introducing a halogenated bisphenol A with a halogen side group, enhances the polarity of the polyester resin, the polarity enhancement being beneficial in increasing the surface tension of the resin. In the process of the high-temperature curing of the metal powder coating, the metal pigment can, under the pulling force of the surface tension of the resin, reduce the influence of gravity sedimentation, thereby stabilizing the metal pigment is stabilized on the surface of the coating, so that the coating shows a better metal effect.
