Features Of Dow CELLOSIZE ER-30M Hydroxyethyl Cellulose

  1. Highly efficient thickener providing excellent viscosity build and pseudoplastic rheology in aqueous systems.

  2. Outstanding water retention capability, critical for performance in cementitious and plaster formulations.

  3. Good compatibility with common surfactants, electrolytes, and other water-soluble polymers.

  4. Non-ionic nature ensures stability across a broad pH range (pH 2–12) without gelation or precipitation.

  5. Consistent batch-to-batch performance supported by Dow’s stringent quality control and traceable manufacturing.

Typical Applications Of Dow CELLOSIZE ER-30M Hydroxyethyl Cellulose

  1. Cement-based tile adhesives and grouts.

  2. Exterior insulation finishing systems (EIFS) base and finish coats.

  3. Self-leveling underlayments and floor screeds.

  4. Joint compounds and drywall muds.

  5. Water-based architectural coatings and texture finishes.
