Infrared analysis of the effect of composition of n-butyltriethoxysilane and gamma-aminopropyltriethoxysilane blends on tertiary amine-catalyzed anhydride-cured epoxy mixtures. Technical report

Technical Report ·
OSTI ID:5469389
The enhancement in mechanical properties observed for silane-treated glass-reinforced epoxy materials is highly dependent on the structure of the coupling agent at the interphase. The effect of varying composition of nonhydrolyzed silane coupling agent blends of gamma aminopropyltriethoxysilane (APS) and butyltriethoxysilane (BTS) on the cure of benzyldimethylamine (BDMA)-catalyzed, nadic methyl anhydride (NMA)-cured diglycidyl ether of bisphenol-A epoxy (BDGE) was studied by Fourier transform infrared spectroscopy (FTIR). The silane blends perturbed the kinetics of the alternating anhydride-epoxy copolymerization reaction, with the perturbation being a nonlinear function of the relative amine concentration in the system.
