Name: Celotech HHB30S Hydroxypropyl Methylcellulose
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Celotech HHB30S Hydroxypropyl Methylcellulose

High viscosity stability across a broad pH range (3–11), ensuring consistent performance in acidic and alkaline formulations.
Excellent water retention capacity, critical for preventing premature drying in cementitious and plaster systems.
Superior thermal gelation profile with reversible gel formation above 65°C, enabling controlled rheology during processing.
Low ash content and high purity, minimizing interference in sensitive pharmaceutical and food-grade applications.
Enhanced film-forming ability and adhesion strength, improving cohesion and workability in tile adhesives and renders.

Typical Applications Of Celotech HHB30S Hydroxypropyl Methylcellulose

Cement-based tile adhesives and thin-set mortars.
Exterior insulation finishing systems (EIFS) and decorative renders.
Pharmaceutical tablet binders and controlled-release matrix formers.
Water-based paints and architectural coatings requiring sag resistance and brushability.
Food-grade thickeners and stabilizers in dairy alternatives and plant-based beverages.
