Highly effective water retention agent for cementitious systems, minimizing premature moisture loss during curing.
Excellent thickening performance with low dosage requirements, enhancing workability and sag resistance in mortars and plasters.
Consistent rheology control across varying temperatures and pH conditions typical in construction chemical formulations.
Non-ionic, compatible with common admixtures including superplasticizers, retarders, and redispersible polymer powders.
Free-flowing, easy-to-disperse powder with low dust generation during handling and dry-mix blending.
Cement-based tile adhesives (C2TE, C2TES1 according to EN 12004).
Exterior insulation finishing systems (EIFS) base and finish coats.
Self-leveling underlayments and floor screeds.
Grouts and repair mortars requiring extended open time and high cohesion.
Tile joint grouts and flexible waterproofing membranes.
