Organofunctional Silanes

Evonik has developed a range of Silanes helping to reach higher performance to adhesives and sealants and brings excellent substrate adhesion, mechanical strength, storage stability, chemical resistance among many other benefits.

Dynasylan® Silanes

Dynasylan® Silanes

The use of Silanes has been a big step forward in the Adhesives and Sealants industry. They have helped to replace sophisticated and expensive process such as screwing, welding or riveting by Adhesives or Sealants.

In addition, thanks to Silanes, Adhesives and Sealants reach high performance even when exposed to moisture or applied to difficult-to-bond surfaces. Organofunctional Dynasylan® Silanes contribute to improve adhesion and increase chemical and temperature resistance among others benefits.

Dynasylan® is a comprehensive range of Silanes that can fulfill Adhesives and Sealants formulators requirements for various end-applications and systems:
