ASSOCIATIVE ACRYLIC THICKENING AGENT CONTAINING POLYGLYCEROLS AND ITS USE TO INCREASE THE OPEN TIME OF THIN OR THICK FILMS

摘要

The present invention relates to new acrylic associative thickening agents which, when polymerized in the presence of particular polyglycerols, ultimately result in an increase of the open time of the paint or of the thick coating in which they are in incorporated. By so doing, painters and applicators will have more time to work the paint layers gradually or to correct imperfections such as paint droplets, and traces of brushes and filling-knives.
