New and updated literature on defoamers
The last two years have seen many changes in the defoamer literature of IM: Older brochures have been revised and new technical bulletins produced on topics of current interest. Four brochures have been available in English since the end of 2011:
TI 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.
TI 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.
TI 1382: Comparison of SIPERNAT® D10 with in-situ hydrophobized fumed silica
Hydrophobic silica can be produced "in situ" during the production process of an defoamer. This TI presents an experimental comparison between hydrophobic SIPERNAT® D10 and selected fumed silica grades that have been hydrophobized in situ.
TI 1391: Improving the 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.
All the brochures can be downloaded as PDF-File from our downloadcenter. Please find the link at the end of this page.
