Hydroxyethyl Cellulose (HEC) is a high-performance rheology modifier and thickener widely used in water-based coatings. As a leading China HEC manufacturer, Celotech provides high-purity HEC with optimized molecular weight and controlled particle size distribution, ensuring consistent viscosity regulation and formulation flexibility.

HEC enhances shear-thinning behavior, improving flow properties, sag resistance, and pigment dispersion for latex paints, emulsion paints, and facade coatings. By forming a colloidal structure, it increases viscosity and prevents premature drying on porous substrates like concrete, masonry, and gypsum, ensuring stable adhesion, smooth leveling, and long-term film integrity. Additionally, Celopro® HEC, supplied by a trusted HEC supplier, offers excellent mildew resistance, storage stability, and durability, making it an essential additive for high-performance paint formulations.
