DOSAGE

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.
