dispersant for PU sealant

The dispersant for PU sealant uses advanced surfactant structures to achieve excellent pigment wetting and distribution. It reduces viscosity variation during mixing and enhances sealant homogeneity. Designed for both moisture-curing and two-component PU systems, it prevents phase separation and pigment floating. It provides better color retention and stable flow, ensuring smooth application in joints and gaps.
