DYNASYLAN 1124

DYNASLYAN 1124 is a bifunctional organosilane possessing a reactive secondary amine where the silicon-functional methoxy- groups hydrolyze in the presence of water to form reactive silanols, which can be bonded to an inorganic substrate. The organophilic amino group in DYNASYLAN 1124 provides basicity at somewhat lower reactivity compared to primary amino groups. This is of major advantage in applications where durability at high temperature and humidity where the silane is added to form prepolymers. It can advantageously be employed in organic solvents or added in situ as a pure substance to the polymer. In higher concentrations (1-5 wt.-%) chemical modification can be achieved by reaction with suitable functional monomers or polymers, for example those containing epoxy groups. It is an important additive in many applications related to advanced materials industry. It improves product properties, such as flexural strength, tensile strength, impact strength and modulus of elasticity.
