Botai THYLOCELL® HB-300 Hydroxyethyl Cellulose HEC Powder For Paints and Coatings

THYLOCELL® HB-100KH is a high-viscosity, non-ionic Hydroxyethyl Cellulose (HEC) with excellent biostability and a high degree of substitution. It dissolves easily in both cold and hot water and provides strong thickening efficiency, superior rheology modification, excellent suspension, and outstanding water retention.

This grade is widely used in latex paints, dry-mix mortars, oil drilling fluids, detergents, polymerization, agriculture, inks, textiles, ceramics, and toothpaste formulations, delivering stable performance across diverse conditions.

Key Benefits:

Strong thickening power with stable viscosity build-up

Excellent water retention, improving open time & workability

Enhances suspension stability and prevents settling

Reliable performance over a wide pH range

Smooth dissolution and easy processing

High biostability for long-term formulation stability
