Hemmings DAPRO Defoamer
Product Description
The Hemmings DAPRO series delivers advanced foam control solutions for waterborne decorative coatings, combining mineral oil and polysiloxane technologies.Designed as VOC-free additives, these defoamers integrate hydrophobic silica and emulsified polymer matrices for rapid bubble collapse across production stages—from pigment grinding to final application
Compatible with semi-gloss, high-gloss, and complex resin systems, the series ensures minimal surface defects while preserving film aesthetics and adhesion. Its dual-action mechanism destabilizes macrofoam at interfaces and disrupts microfoam stability within the coating matrix, achieving efficient air release without compromising gloss or color uniformity.
