Wetting Agent for Architectural Coatings
Wetting agents for architectural coatings are surfactant-based additives that reduce the surface tension of waterborne paint formulations, enabling uniform substrate wetting and preventing crawling, pinholes, and adhesion failures. They are compatible with both anionic and non-ionic latex systems and improve pigment dispersion efficiency during the manufacturing process. These products are essential for achieving uniform film formation on challenging substrates including masonry, concrete, and weathered surfaces.
