Wacker Group unveils silicone-based impact modifiers for composites at JEC World

Mar 11 2026

The WACKER Group is presenting two new impact modifiers for composites at this year’s international composites show JEC: GENIOPERL® W37 and GENIOPERL® W38. 

Both products represent a new generation of silicone-based additives that significantly improve the mechanical properties of thermosetting resins. Another product at the booth is POWERSIL® Resin 710. The silicone compound can be processed by compression molding, pressure gelation, or even injection molding technologies. Molded parts made from the product comply with thermal class R and are therefore able to withstand temperatures of up to 220°C for extended periods of time. JEC World takes place in Paris, France, from March 10 to 12.
