Features Of Ashland Natrosol Plus 330 Hydrophobically Modified Hydroxyethyl Cellulose

  1. Enhanced rheology control with strong shear-thinning behavior and excellent suspension capability.

  2. Improved water resistance and film integrity due to hydrophobic modification.

  3. Outstanding compatibility with surfactants, electrolytes, and common co-binders in aqueous systems.

  4. Easy dispersion and rapid viscosity development without requiring pH adjustment or neutralization.

  5. Provides long-term storage stability and reduced sagging in vertical applications.

Typical Applications Of Ashland Natrosol Plus 330 Hydrophobically Modified Hydroxyethyl Cellulose

  1. Architectural coatings (e.g., interior/exterior paints and primers).

  2. Textile printing pastes requiring high wet-film stability and sharp pattern definition.

  3. Tile adhesives and cementitious repair mortars for improved workability and anti-sag performance.

  4. Industrial maintenance coatings where water resistance and pigment suspension are critical.

  5. Decorative plasters and skim coats demanding smooth application and extended open time.
