Features Of Ashland Culminal 9166 Cellulose Ether

  1. Highly efficient water retention for extended workability in cementitious systems.

  2. Excellent viscosity build and pseudoplastic rheology for improved sag resistance and pumpability.

  3. Consistent batch-to-batch performance due to stringent GMP-compliant manufacturing control.

  4. Enhanced adhesion to substrates, supporting bond strength in tile adhesives and repair mortars.

  5. Good compatibility with common admixtures including superplasticizers and redispersible polymer powders.

Typical Applications Of Ashland Culminal 9166 Cellulose Ether

  1. Cement-based tile adhesives (thin-set and thick-bed formulations).

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

  3. Self-leveling underlayments and floor screeds.

  4. Repair mortars and grouts for concrete restoration.

  5. Stucco and decorative renderings requiring controlled open time and crack resistance.
