TEXTURECEL™ 1000 GA
TEXTURECEL™ 1000 GA is granular sodium carboxymethyl cellulose used in paper coating, ceramic, and adhesive applications as a thickener and binding agent.
TEXTURECEL™ 1000 GA is a low molecular weight sodium carboxymethyl cellulose (CMC) polymer. It is a naturally derived cellulose ether presented in granular form that can be directly added at 1% in aqueous formulations to produce solutions with a viscosity of approximately 1,000 cPs. TEXTURECEL™ 1000 GA is used as a thixotropic rheology modifier in water-based coating, ink, and adhesive formulations. TEXTURECEL™ 1000 GA is particularly useful in paper coatings as both a thickener and film former. It produces clear, durable films that are highly resistant to oil and grease. In ceramic applications, TEXTURECEL™ 1000 GA is used as a temporary binder that improves green strength prior to being burnt out cleanly during sintering.

Problems Solved
Damage done to paper and paper coatings caused by exposure to oily chemicals Inadequate leveling and adhesion of coatings, inks, and adhesives due to a lack of shear-thinning rheology Ceramic defects leading to the rejection of ceramic parts Use of rheology modifiers and thickeners that are not based on renewable resources like cellulose
