2results about How to "Good substrate adhesion" patented technology

The application relates to the technical field of powder coating, in particular to a powder coating suitable for laser curing and a preparation method and application thereof. The powder coating for laser curing comprises the following components in parts by weight: resin, curing agent and heat-conducting agent, and other components; the mass ratio of the resin, the curing agent and the heat-conducting agent is 50-90:510:510; the heat-conducting agent is selected from two or more of graphene oxide, nano-aluminum oxide, carbon nanotubes, aluminum nitride and hexagonal boron nitride. The powder coating for laser curing of the application has excellent surface gloss, flatness and substrate adhesion after laser curing, and has good chemical corrosion resistance, and can realize a curing effect equivalent to that of current conventional thermal curing, and has significant application value in the fields of decoration and protection.

According to the present invention, a cured coating having exceptional water and oil repellency and abrasion resistance as well as exceptional chucking properties can be formed by using a fluoropolyether-group-containing polymer having a silanol group or a hydrolyzable silyl group represented by formula (1) (Rf is a divalent fluoroxyalkylene-group-containing polymer residue, U is a divalent or trivalent organic group, Z is a silalkylene structure or a silarylene structure, Y is a divalent organic group, R is a C1-4 alkyl group or a phenyl group, X is a hydroxyl group or a hydrolyzable group, n is 1-3, and m is 1 or 2) as a surface treatment agent including said polymer and / or a partial (hydrolyzed) condensate thereof.
