Silicone defoamers and silicone antifoams contain non-ionic surfactants & functional additives and highly hydrophobic silicone oils. They are intended for high end application for defoaming.
100% active Liquid Non Silicone Defoamers work well in Solvent based as well water based systems.
Powder Defoamers not only burst the foams but control re-generation of foam and have excellent defoaming action. They are ideally suitable for products supplied in dry form.
