Silicone Additive Enhances Exterior Aesthetics

Dow Performance Silicones has introduced Dow Corning 904H Coating Additives, a silicone additive for architectural facade coatings that supports enhanced aesthetics for building exteriors. It helps reduce the “snail trail” effect, which frequently is seen in cold and humid climates when surfactants and other water-soluble ingredients in coating formulations leach to the surface. The additive, which can be added to existing formulations, also can improve water resistance, repellency and beading in coatings by increasing their surface hydrophobicity.
