The last two years have seen many changes in the defoamer literature of Evonik - Inorganic Materials.
Older brochures have been revised and new technical bulletins produced on topics of current interest. Three brochures all around "AEROSIL® fumed silica for defoamers" have been available since the end of 2011:
- Technical Information - No. 1313:
SIPERNAT® and AEROSIL® for Defoamer
This brochure offers a broad overview of theoretical aspects of foam and defoamers, describes Evonik silica products that are particularly suitable for defoamer production, and introduces Evonik's products and services for technical customer support.
- Technical Information - No. 1381:
AEROSIL® and SIPERNAT® – Efficient booster for defoamer in paints and coatings
This brochure describes how AEROSIL® and SIPERNAT® effectively improve the performance of polyether siloxane based defoamer formulations in three different latex binder systems of water-based paints and coatings.
- Technical Information - No. 1391:
Improving Sedimentation Stability of SIPERNAT® D 10 in Mineral Oil based Defoamer Formulations
This TI describes the results of systematic experiments for stabilizing oil-based defoamer formulations. These formulations contain SIPERNAT® D 10 and are further stabilized with selected hydrophilic or hydrophobic AEROSIL® grades.
