A silicone-epoxy hybrid resin was cured with 3-aminopropyltriethoxysilane (AMEO) and AMEO/3-aminopropyltrimethoxysilane (AMMO) mixture. The effect of resin-to-hardener ratio on cured system properties was investigated. Thermal behavior of the cured resin was analyzed by DSC and TGA analyses. Hardness, adhesion properties, solvent and chemical resistance of the films cured at different resin-to-hardeners ratio, were compared. It was shown that the obtained Tg values of the cured resins are similar for both cure systems, however the use of AMMO as a curing agent in a mixture with AMEO can provide significant shortening of the curing time. The solvent and chemical resistance as well as the hardness and adhesion properties of the cured resin samples were excellent. The best results are registered for the system cured with AMEO hardener.
