Abstract
A process for producing a coating composition includes separately chemically grafting particles with compounds having reactive groups and compounds having hydrophilic polymer chains. The hydrophilic polymer chains dissolve in water at least one temperature between 0 and 100° C. The reactive groups may react with the substrate and or react with one another to form a cross-linked coating, comprising the particles. A process for forming a coating on a substrate is also provided.
Claims20
A coating composition comprising inorganic particles grafted with:
- (a) reactive groups, and
- (b) hydrophilic polymer chains comprising at least an average of 5 monomer units of ethylene oxide or vinyl pyrrolidone.
