ABSTRACT:
Shelf life of silica based defoamer composition is improved by adding oil soluble resins and optionally aliphatic fatty acids to retard separation and to inhibit settling. The composition is useful in preventing foaming or in defoaming aqueous systems such as water based protective coatings, adhesives, black liquors and monomer stripping.
