Dynasylan® Silanes

Many PU formulators are facing significant challenges when formulating polyurethane adhesives, especially when it comes to primerless adhesion to critical substrates and metals.

VPS 7161 is a special silane adhesion promoter with a planar structure and a very high crosslinking potential. It shows excellent chemical compatibility to amine-critical, sensitive isocyanates that makes it a tailor-made solution for PU-based adhesives.

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.

• 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

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.

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.

Adhesion on critical substrates like plastics is a key challenge in the adhesive industry. It comes along with the difficult task to keep other performances like mechanical properties at a suitable level. What if you could go even beyond and get adhesion on critical substrates along with increased mechanical properties and VOC reduction?
