Performance Silica have found their way with numerous applications into many branches of industry. This also applies to their use as carrier for liquid or pasty substances as well as the application as flow aid for powdered or granular products. With numerous hydrophilic and hydrophobic AEROSIL® Fumed Silica as well as Sipernat® Precipitated Silica, Evonik offers the best choice of problem solvers worldwide.
Hydrophobic silica products are well known as efficient booster for defoamer formulations which are used in a variety of industries and applications. This Technical Brochure describes how AEROSIL® fumed silica and SIPERNAT® specialty silica products from Evonik effectively enhance the performance of polyether-siloxane based defoamer formulations in three different latex binder systems commonly used in waterborne paints and coatings.
