Thickener
CAS Number: 9004-32-4
Hydroxyethyl cellulose (HEC) based thickener widely used in waterborne coatings, adhesives, and construction products to build viscosity and improve sag resistance. It provides excellent pseudoplastic flow behavior, ensuring easy application while preventing dripping on vertical surfaces. Non-ionic in character, it exhibits broad compatibility with most paint additives.
