The Universal Selection Source: Adhesives Ingredients

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.

Case Studies from Organofunctional Silanes

Formulate green adhesives & sealants with broad adhesion performance in difficult conditions thanks to Dynasylan® 1146

Thanks to Dynasylan® 1146, formulators can develop Adhesives & Sealants with outstanding adhesion performance and an important water-repellent effect. It also allows formulating environmentally friendly and safe Adhesives or Sealants.It is particularly suitable for Construction, Parquet applications and Transportation.


Formulate highly flexible and durable SMP-based Adhesives & Sealants thanks to Dynasylan® 1189 Aminosilane

Dynasylan® 1189 is an accompanied adhesion promoter for moisture curable SMP-based adhesives and sealants. When exposed to moisture and incorporated into the final siloxane network, Dynasylan® 1189 exhibits specifically high flexibilities. Further important side effects of formulating Dynasylan® 1189 are better chemical and moisture resistance of the finished products.


Formulate elastic adhesives & sealants with broad adhesion spectrum and reduced yellowing thanks to Dynasylan® SIVO 203

High elastic adhesives and sealants for visible interior and exterior bondings are widely used in the market. Consequently, to limit the discoloration of visible adhesive and sealant joints is crucial for the quality of such products.

With Dynasylan® SIVO 203, formulators can develop Adhesives & Sealants with excellent adhesion performance, high bonding strength, high elasticity and reduced yellowing.
