Tego® Antifoam 2450 is an organic antifoam concentrate based on vegetable oil. Tego Antifoam 2450 is designed for the use as a process aid in the water-based polymerization of SBR/NBR rubber materials. Unlike conventional defoamers, Tego Antifoam 2450 was specifically developed to avoid premature coagulation. This allows for less cleaning of the reaction vessel and the demonomerization column while the Tego Antifoam 2450 does not hinder the coagulation stage.
Tego® Antifoam 2291 is a self-emulsifying APEO-free organic antifoam concentrate. The product is absolutely free of silicone and does not contain any silica. Tego Antifoam 2291 destroys foam or prevents foam formation reliably in aqueous media and may be used for foam control in a variety of industrial applications, even where the use of silicone and silica is not accepted:
Process aid for water-based polymerization of dispersions, thermoplastics and elastomers
In formulation and application of polymer dispersions/lattices
In underwater granulation of additive masterbatches or compounds
In a multitude of other industrial applications
