AEROSIL® news

New and updated literature on defoamers

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.


All the brochures can be downloaded as PDF-File from our literature database at aerosil.com (Login required). Please find the link at the end of this page. Printed copies are available by email: aerosil@evonik.com - please do not forget your postal address.
