Botai DEMACSA®P-131 Polycarboxylate Ether PCE Superplasticizer Powder High Performance Concrete & Mortar Admixture

DEMACSA® P-131 is a polycarboxylate-ether-based (PCE) superplasticizer powder developed through advanced molecular configuration optimization and precision-controlled polymerization technology. It provides high water-reducing performance, strong dispersion effect, and excellent compatibility with cement and gypsum systems.

Designed for cement-rich mortars and concrete requiring high fluidity and strength, P-131 offers long workability retention, reduced air entrainment, and improved overall performance, while maintaining environmental safety and low dosage efficiency.

Key Benefits:

High water-reducing ratio (≥ 25 %) for enhanced fluidity and strength

Long slump retention and consistent workability across construction cycles

Excellent compatibility with both cement- and gypsum-based systems

Rapid defoaming and low air content for smooth surface finishes

Eco-friendly formulation, free from harmful substances or formaldehyde

Consistent performance in high-strength, self-leveling, and repair applications
