Silicone Defoamers and Antifoams

Silicones are widely used as defoamers and antifoams in pulp and paper, paints and coatings, water treatment, metalworking fluids, and other industrial applications. Siltech offers a range of defoamers, which include basic emulsions of hydrophobized silica as well as specialized silicone polyethers that are effective in many demanding applications and sensitive applications. These include paints and coatings, pulp and paper, or use in metalworking fluids where post-treatment such as paintability is important.
