Adhesives and Sealants
Dynasylan® for good adhesion
Silanes for powerful adhesives and sealants with long-lasting adhesion
The use of silanes in the adhesive and sealant industry has contributed to replacing difficult joining processes such as welding, screwing or riveting with adhesives or sealants. This offers numerous advantages, as adhering gives the bonded materials additional damping characteristics and a high level of dynamic strength among other things. At the same time, tension is distributed evenly and the materials are not weakened by drilled holes. All this can extend the lifespan of the final products.
Silanes’ diverse properties make them ideal for a multitude of adhesive and sealant applications, such as in the transport and construction industries. Organofunctional products from the Dynasylan® portfolio improve adhesion, and can also be used as crosslinking agents, water scavengers or polymer and rheology modifiers.
Adhesion Promotion
Bonding materials together is often simpler and more effective than fastening them mechanically. Silanes for adhesion promotion make this possible. ... MORE
Crosslinking
Silanes can be used as crosslinkers and co-crosslinkers to permanently bond materials together. Among other things, they ensure heat resistance and a stable bond. ... MORE
Drying
Special products like the vinylsilane Dynasylan® VTMO work as moisture scavengers in adhesive and sealant formulations to eliminate unwanted moisture quickly and efficiently. ... MORE
Polymer modification
Specialty silanes can be used to produce silane-modified polymer adhesives and sealants (SMPs). They impart properties to the polymer such as good adhesion to different substrates, good crosslinking, excellent mechanical strength and temperature resistance. ... MORE
Reinforcement
In adhesives and sealants, silanes can significantly enhance the final formulation. By coupling the fillers with the polymers, the mechanical properties of the cured formulations increase significantly, and the resistance and tightness of these systems are also significantly increased. ... MORE
Rheology Modification
Silanes from Evonik can improve the flow properties of adhesives and sealants, making them easier to manufacture and handle. They also enable formulation optimization, such as higher filling grades. ... MORE
