Features Of Ashland Benecel A40M Methyl Cellulose

  1. High viscosity performance in cold water with rapid, low-foam dispersion.

  2. Excellent thermal gelation profile—forms reversible gels upon heating and re-solubilizes upon cooling.

  3. Superior film-forming capability for enhanced surface protection and cohesion in dry-mix formulations.

  4. Consistent batch-to-batch rheological behavior due to tight molecular weight and substitution control.

  5. Non-ionic nature ensures compatibility with electrolytes, surfactants, and other common formulation ingredients.

Typical Applications Of Ashland Benecel A40M Methyl Cellulose

  1. Cement-based tile adhesives and grouts requiring extended open time and sag resistance.

  2. Self-leveling underlayments where controlled flow, leveling, and edge retention are critical.

  3. Exterior insulation finishing systems (EIFS) base and finish coats for crack bridging and workability.

  4. Dry-mix mortars including plaster, stucco, and repair mortars demanding improved water retention and pumpability.

  5. Water-based architectural coatings as a rheology modifier and stabilizer for pigments and fillers.
