Drew™ powder defoamers are polyols and fatty acid ester foam control agents for use in dry blend formulations which are dispersed in water before application. Drew powder defoamers are especially effective for use in building applications such as cement, fillers, gypsum, leveling compounds and mortars and can also be applied in powder paints or adhesives. Drew powder defoamers are typically effective at dosage levels between 0.1-1.0 percent by weight on total formulation.

A flowable product, Drew powder defoamer can be easily mixed into dry blend formulations, which are then dispersed in water before application. The addition of Drew powder defoamers results in low foaming solutions or pastes with low entrained air content. In some dry system formulations, Drew powder defoamer reduces clumping.
