GENIOSIL ® silane-modifed polymers allow the formulation of adhesives that combine high strength and elasticity. VINNAPAS ® solid resins prevent shrinkage during curing.
GENIOSIL ® silane-modified polymers used as a binder for industrial adhesives can achieve elastic yet strong bonds. As α-based formulations totally eliminate the need for tin as the catalyst yet can achieve properties previously only attainable with toxic solutions, formulators look increasingly to compound using this novel technology. Adhesives based on GENIOSIL ® XB have outstanding adhesive strength, even when bonding dissimilar materials. For applications where strength yet elasticity is required, the GENIOSIL ® XT range will be the product of choice. Industrial adhesives are often exposed to dynamic stress, the GENIOSIL ® XT range will give tear resist values of >30 N/mm, yet remain elastic to absorb such stress.

Acrylic-based structural adhesives score points for conferring very good adhesion on difficult substrates in addition to faster curing and flexibility. The performance of a structural adhesive is determined by the permanence of the bond between the adherends. The adhesive must shrink very little as it cures. VINNAPAS ® solid resins reduce shrinkage during curing, thereby speeding up processing and providing a reliable bond.
- Reduced shrinkage
- Faster processing
- Reliable bond
- Acrylic-based structural adhesives
Epoxy-resin-based adhesives can be effectively rendered thixotropic by means of hydrophobic HDK®. In the bonding of rotor blade half-shells, for example, HDK® prevents the adhesive from running. In adhesive formulations, hydrophobic HDK® prevents fillers from settling, significantly increasing the storage stability of the system.
The rheological properties of acrylate systems can be effectively controlled using HDK® products. In special applications, reactive HDK® can improve mechanical properties such as scratch resistance and tensile strength.
