defoaming agent for polyurethane

The defoaming agent for polyurethane works through chemical dispersion and surface tension reduction, ensuring rapid air release during mixing and casting. It provides stable defoaming under high shear and temperature, maintaining clear, uniform coatings or foams. Available in silicone and mineral oil bases, these agents ensure compatibility with various PU formulations. Their anti-cratering behavior helps achieve smooth finishes and consistent curing without residue or gloss reduction.
