Based on the innovative alpha-technology, the new GENIOSIL® XB hybrid polymers for the first time exploit the advantages of silane crosslinking for user-friendly, environmentally compatible structural adhesive bonds.
Thanks to their low viscosity, the new hybrid polymers are easy to compound. In particular, they can be formulated without using plasticizers or solvents. The use of tin catalysts can now also be eliminated – yet another advantage of using alpha-silane technology.
Adhesive formulators can modify the mechanical end properties and tailor them to requirements by adding other components such as fillers or catalysts. Adhesives based on GENIOSIL® XB cure upon contact with humidity in the ambient air to form thermosets and attain hardness in the upper Shore D range. In terms of adhesive strength, these adhesives are making advances into what used to be the exclusive domain of epoxy- and isocyanate-crosslinked systems. Depending on the substrate, the tensile lap-shear strengths can reach 15 N/mm².
They cure without blistering, develop strength quickly and adhere to many commonly used materials such as wood, glass, metals and ceramics – with no need for primers.
For formulators as well as end-users, the new hybrid polymers offer a range of advantages:
