Organofunctional Silanes

Evonik
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®: a multi-purpose technology

Organofunctional Silanes exhibit a bridge-building property which is particularly important in 5 fields:

How is it possible?

Organofunctional silanes are silicon-based chemicals containing two groups, inorganic and organic, in the same molecule:

  • Alkoxy groups (hydrolysable) such as methoxy-, ethoxy-, etc .
  • Organo-functional group, such as amino-, epoxy-, vinyl-,etc .

These two groups exhibit different reactivity and allow sequential reaction.

Most of the Silanes act as a bridge between organic and organic/inorganic components.

The function and molecular (chemical) nature of the organic polymer will determine the choice of Silane. And the dosage is specific for each formulation.
