ZEOFOAM™ 166 silica is a defoamer precursor designed for either dry roast or in-situ hydrophobic surface treatment. ZEOFOAM™ 166 silica is effective in a wide range of defoamers, from paints and coatings to paper, and can be used universally for all defoamers within a wide range of industries.
ZEOFLO® silica is a hydrophobic defoamer, which has been pre-treated in a special process to make them ready for use in either mineral oil or silicone oil based defoamer formulations. ZEOFLO® TL and ZEOFLO® MD silicas have been specifically tailored to provide excellent foam knockdown and foam suppression in a variety of applications including paint and coatings, paper, textile and water treatment.
