Abstract:
Finely divided tetrachloroisophthalonitrile powder is dispersed in a vehicle which is a mixture of calcium alkyl aryle sulfonate, nonionic surfactant, fatty acid or other ester, coupling agent and optionally lecithin. The vehicle provides a water and organic solvent compatible tetrachloroisophthalonitrile dispersion having a pourable and pumpable viscosity as well as settling resistance which is useful as an antimicrobial agent in both water-based and solvent-based protective coatings such as paints.
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.
