Associative cellulose ethers are primarily used in the paint industry to increase spatter resistance and coverage of paint. They are generally derived from hydroxyethyl cellulose and ethylhydroxyethyl cellulose by modifying them with hydrophobic groups (alkyls or alkyl aryls). The concentration of hydrophobic groups is normally kept low (<2 %). The hydrophobic groups are able to interact with other paint components and thus provide associative characteristics. They achieve thickening via both aqueous-phase thickening and associative thickening. There­fore, they exhibit a certain degree of dependence on other components of paints such as binders, pigments, extenders and surfactants, but the dependence is not as strong as in the case of other types of associative thickeners.
