Reacted Silica Defoamer

NOFOAM -1976 is a dispersion of a hydrophobic solid in oil and may separate upon standing. It should be mixed well before each use. All ingredients in NOFOAM -1976 are listed under 21 CFR 175.105 Adhesives, 175.200 Defoaming agents used in coatings, 176.210 Defoaming agents used in the manufacture of paper and paperboard.

NOFOAM -1976 is a versatile defoamer/antifoam agent useful in a wide variety of industrial applications. It is stable in conditions of extreme pH ( < 1 to 14 ) and temperatures > 350 °F and thus finds use in such diverse applications as phosphoric acid production, caustic digestion of aluminum ores, jet dyeing. NOFOAM -1976 combines the best properties of organosilicone and organic based foam control agents.

NOFOAM -1976 is a silicone-free dispersion of a surface modified inorganic silica in mineral oil. Coatings using NOFOAM-1976 are not subject to pinholes or recoating problems as sometimes occurs with silicone based foam control agents. NOFOAM -1976 also resists hydrolysis in strong alkali which occurs with some silicone based foam control agents. NOFOAM -1976 has also been successfuly used in adhesives, detergents, effluent treatment, emulsion polymerization, gas treating, ink, mining, paints, paper coatings, processing and pulping, & textile processes.
