Ashland NATROSOL 250HBR Hydroxyethyl Cellulose

Ashland NATROSOL 250HBR is a water - soluble non - ionic hydroxyethyl cellulose surface - treated with glyoxal, tailored for various water - based coatings and surface coatings. It is a white to beige powder, acting as a high - efficiency thickener, water retention aid and rheology modifier, capable of accurately controlling rheology throughout the application cycle, providing mechanical and chemical stability

Features Of Ashland NATROSOL 250HBR Hydroxyethyl Cellulose

  1. Precise Rheology Control - Controls system rheology throughout the cycle, ensuring smooth construction and improving coating appearance and uniformity

  2. High - Efficiency Thickening and Water Retention - High thickening efficiency, strongly locks water, reduces coating cracking and extends open time

  3. Outstanding Stability and Compatibility - Compatible with various water - based system materials, good chemical and mechanical stability, stable between batches

  4. Easy Dispersion and Dissolution - Disperses quickly without agglomeration, easier to dissolve, reducing production operation difficulty and time consumption

Typical Applications Of Ashland NATROSOL 250HBR Hydroxyethyl Cellulose

  1. Architectural Water - Based Coatings - Thickens and retains water in interior/exterior latex paints, controls sagging and anti - splashing, and improves construction and storage stability

  2. Industrial Surface Coatings - Thickens water - based primers and topcoats for metals/wood, ensures uniform film formation and enhances coating protection

  3. Water - Based Adhesives - Acts as a protective colloid and stabilizer, improves bonding strength, and optimizes colloid rheology and storage stability

  4. Pigment Dispersion Systems - Prevents pigment settlement and facilitates redispersion, ensures uniform and stable dispersion systems, and improves product quality
