Hydroxyethyl Cellulose (HEC) is an essential additive in water-based coatings, offering efficient thickening and rheology control to enhance construction performance—such as splash resistance, flow resistance, and workability. It also improves storage stability, prevents pigment settling, and ensures uniform color consistency by promoting even pigment dispersion.

HEC’s high water retention slows down drying, helping to prevent film cracking and improve surface quality. Environmentally friendly and non-toxic, HEC is fully compatible with low-VOC formulations and is widely used in building latex paints, industrial coatings, and specialty paints.

For best results, HEC should be pre-dispersed in cold water and added in appropriate amounts (0.1%–1.5%) to balance viscosity and drying speed, while achieving excellent film formation and long-term anti-mold performance.
