SYUDOX® WRP-150A
Water Reducing Agent [Powder]
SYUDOX® WRP-150A is a powder water reducing agent for the addition in construction site or premixed products.
- Enable to mitigate slump-loss effect sharply.
- The stable performance is shown on any temperature condition.
- The workability is stable, due to hardly dosage dependence.
- Easy to mix with other powder.

Depending on the application, the dosage of SYUDOX® WRP-150A varies from 0.5 to 3.0wt% of the cementitious material. SYUDOX® WRP-150A contains no defoaming agent.
It might give higher air content depending on the application. For controling the air content, we recommend the use of powder defoaming agent, SYUDOX® DEF-001-CS, with dosage of 0.5-1.0wt% of SYUDOX® WRP-150A weight to be added before use.
