CIF price is over 10% cheaper than other PCE,JSB PCE powder offering Easy, Efficient, and Economy.(*based on solid content unit price comparison)

WRP-4 Polycarboxylate Superplasticizer (PCE) Powder

High-range water-reducing admixture powder


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

For optimal results, it is recommended to use WRP-4 at a dosage ranging from 0.02% to 0.5% of the cementitious binder in various applications.


WRP-4 is dissolved in water and then diluted with water to achieve liquid solutionswith different solid contents. Please note that we recommend a maximum solidcontent of 40%.


WRP-4 provides exceptional control over both initial and final setting times. Thesetting times of concrete mixes may vary depending on factors such as cementtype, mix design, and ambient temperature.


Toensure compatibility and avoid any potential issues, it is advised not tocombine PCE powder with any other admixture unless prior approval is obtained from JSB.
