Features Of Ashland LHB250C Cellulose Ether

  1. High viscosity build and excellent water retention in cementitious systems.

  2. Improved workability and extended open time for tile adhesives and renders.

  3. Enhanced sag resistance for vertical applications without compromising pumpability.

  4. Consistent rheological performance across varying temperatures and pH conditions.

  5. Low foam generation during high-shear mixing, supporting efficient industrial processing.

Typical Applications Of Ashland LHB250C Cellulose Ether

  1. Cement-based tile adhesives (C2TE, C2TES according to EN 12004).

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

  3. Self-leveling underlayments and flowable floor screeds.

  4. Grouts and repair mortars requiring controlled setting and reduced shrinkage.

  5. Joint fillers and flexible thin-bed adhesives for large-format tiles.
