WRP-4 Polycarboxylate Superplasticizer (PCE) Powder
High-range water-reducing admixture powder
Description
WRP-4 is a highly efficient, free-flowing, and spray-dried powder composed of a newgeneration polycarboxylate-based polymer. It serves as a superplasticizer forcement-based materials, offering exceptional performance. Additionally, it functions as an excellent dispersion plasticizer suitable for gypsum, ceramic,and other mineral materials.
WRP-4 is specifically designed as a superplasticizer for high-performance concrete,high-strength concrete, high-volume fly ash/slag concrete, as well as grouting, self-leveling screed, and mortar applications. It meets the ASTM C 494, Type-F specifications, ensuring its quality and reliability.
Special Features
Comparedto naphthalene(NSF) , WRP-4 exhibits superior characteristics, including:
-Remarkable water reduction capability of up to 30%
-Excellent stability, providing an extended working time
-Unique homogeneous plasticizing property, effectively preventing segregationand bleeding
-Effective dispersal agent for various types of cement, gypsum, and minerals
