Overview
METHOCEL™ A4C Premium is a water-soluble methylcellulose polymer with very high purity. This grade is used as a thickener, binder, and film former. METHOCEL™ A4C Premium will reversibly gel at temperatures above 55°C. Solutions containing METHOCEL™ A4C obtain pseudoplastic rheology. These properties make it an ideal binder for ceramics to boost green strength and a perfect thickener for paints, coatings, and adhesives to make them more easily spread, retain adhesion on vertical surfaces, and form films with high integrity. METHOCEL™ A4C Premium also helps to maintain stability in suspensions and emulsions to increase the storage life of the aforementioned products. METHOCEL™ polymers have excellent stability in extreme pH and can provide viscosity control in both acidic and alkaline systems.
