Ashland Natrosol 250HBR is a non-ionic water-soluble hydroxyethyl cellulose (HEC), tailored for water-based coatings and adhesive systems. It is a fine granular powder with a viscosity of 30000CPS in 2% aqueous solution, featuring enzyme resistance and delayed hydration. It forms a stable thickening structure through hydrogen bonds, with clear aqueous solution
Enzyme-Resistant Long-Term Stability - Excellent enzyme resistance, resisting biodegradation, stable viscosity without attenuation during long-term storage, extending shelf life
Delayed Hydration for Easy Processing - Delayed hydration characteristics, good dispersibility, preventing agglomeration, suitable for various coating production processes, easy to operate
Full-Range Stable Thickening - Unaffected by pH, emulsion type, pigments and fillers, stable thickening effect, reliable performance after water dilution
Clear and Excellent Color Development - Clear and transparent aqueous solution, good color development, improving the color reduction and surface texture of coatings
Architectural Coating Systems - Thickening of latex paints, real stone paints, texture paints, multi-color coatings, etc., preventing sedimentation and sagging, improving construction and storage stability
Water-Based Adhesives - Increase viscosity and water retention, prevent component stratification, enhance bonding strength and storage stability
Industrial Coating Field - Rheology control of water-based industrial paints, suitable for multiple construction methods, ensuring coating uniformity and weather resistance
Acrylic Paint Manufacturing - Thickening and improving pigment stability, ensuring color uniformity, enhancing pigment adhesion and durability
