FORMULATING GLOSS EMULSION PAINTS WITH CELLULOSE ETHER-BASED ASSOCIATIVE THICKENERS

Commercial grades of hydrophobically modified hydroxyethyl cellulose ( HMHECS) have been widely accepted in the point industry os theology mo difiers for latex paints. These products provide paints with improved theology compared to those point systems thickened through a non-assoc iative thickening mechanism. Nevertheless, the rheology requirements f or high gloss emulsion paints ore more severe and have led to the deve lopment of a new generation of cellulose ether based associative thick eners. This paper describes the formulating variables which should be considered when using these low molecular associative cellulose ethers in glass emulsion points.
