Features Of Celotech HHB2000S Hydroxypropyl Methylcellulose

  1. High viscosity grade offering excellent thickening and rheology control in aqueous systems.

  2. Superior thermal gelation profile with reversible gel formation above 60–65 °C.

  3. Excellent water retention capacity, critical for cementitious and plaster formulations.

  4. Consistent batch-to-batch performance ensured by stringent GMP-compliant manufacturing.

  5. Low surface tension and high compatibility with common construction additives (e.g., redispersible polymer powders, superplasticizers).

Typical Applications Of Celotech HHB2000S Hydroxypropyl Methylcellulose

  1. Tile adhesives and grouts requiring extended open time and sag resistance.

  2. Dry-mix mortars including self-leveling compounds and rendering plasters.

  3. Exterior insulation finishing systems (EIFS) base coats and thin-bed renders.

  4. Water-based architectural coatings for improved brushability and film formation.

  5. Non-asbestos fiber-reinforced cement boards and precast concrete admixtures.
