Technical Information 1391: Improving Sedimentation Stability of SIPERNAT® D 10 in Mineral Oil based Defoamer Formulations (pdf, 660,38 KB)
SIPERNAT® D 10 is well known in the industry as excellent booster silica for liquid and powder defoamer formulations. AEROSIL® fumed silica is often used to increase the viscosity and thixotropy of liquid formulations such as epoxy resins and special polyurethane systems. Therefore, we systematically studied the effect of selected AEROSIL® fumed silica grades on the sedimentation stability of different defoamer formulations containing SIPERNAT® D 10 as booster silica.
