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® 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:

Case Studies from Organofunctional Silanes

Balance the mechanical properties of SMP and Silicone Adhesives & Sealants. Formulate highly elastic SMP and Silicones Adhesive & Sealants

Highly elastic SMP and silicone adhesives & sealants become more and more important in the market. To fulfil the market requirements and norms, the mechanical properties of SMP and silicone adhesives and sealants must be well-balanced. Especially expansion sealing joints in the construction industry, floor and connection joints and special adhesives like elastic parquet adhesives require extensive adhesion properties and elastic behavior, which can be adjusted using specific organofunctional silanes in the SMP and silicone formulations.

Read the case study to read about Dynasylan’s® comprehensive range of monomeric and oligomeric silanes offering excellent adhesion and cohesion properties.

  • Dynasylan® special amino functional silane oligomers (e. g. Dynasylan® 1146) offer well balanced mechanical properties and excellent adhesion profiles of SMP and silicone adhesives & sealants
  • Dynasylan® secondary amino silanes (e.g. Dynasylan® 1189 and VPS 1489) help to formulate SMP and silicone adhesives & sealants with enhanced elasticities

Formulate environmentally friendly adhesives and sealants with Dynasylan® silanes

Environmentally friendly adhesives and sealants with reduced VOC as well as enhanced labeling become more and more important in the market.

The main challenge is to reduce the VOC content of the final formulation and to have a positive influence on the labeling while securing good adhesion performance Dynasylan® has a comprehensive range of oligomeric silanes offering excellent adhesion properties and significantly reduced VOC (up to 75 % VOC reduction) compared with traditional monomeric silanes.

Moreover, oligomeric silanes often display significant advantages in labeling and can enhance final strength and elasticity as well as other properties of adhesives and sealants.

Formulate transparent SMP-based adhesives & sealants

Many formulators are facing significant challenges when formulating transparent SMP-based (silane modified polymers) adhesives and sealants. Next to questions around transparency or rheology (where AEROSIL® fumed silicas play an important role), the subsequent creeping of yellowing of such products during storage or even service lifetime are the key for a successful market entry.
