The Dow Corning AF-3258 PulpAid compound is a 100% active silicone antifoam designed to control foam in aggressive foaming environments typically encountered in chemical pulping, such as kraft and sulfite pulp washing. Compared to mineral-oil-based defoamers, this product provides excellent foam knockdown and persistence at lower use levels. The AF-3258 PulpAid compound must be formulated into a dispersion or emulsion prior to addition to the foaming media. Formulators can prepare AF-3258 PulpAid compound aqueous emulsions using many common commercially available emulsifiers and preservatives. Other ingredients that can be formulated with the product include siloxylated polyethers, hydrophobic silica and organic glycols.
