Improved thixotropic agents, thixotropic paint compositions containing them, and process for preparing the same.

摘要

Improved thixotropic agents are disclosed which are produced by the reaction of (i) xylylene or C4-C8 diamine, and (ii) C1-C11 carboxylic acid, and (iii) polymer fatty acids. Molar ratio of (i) to (ii) is from 1:1 to 2:3, and ratio of amine groups in (i) to acid groups in (ii) + (iii) is about 1:1. Paint compositions containing them are also disclosed, as well as a process for incorporating the thixotropic agents (a) under the form of a concentrated solution (b) either into the paint, or into the hardener, or even distributed amongst the paint and the hardener.
