Investigation of Wear Properties of Toughened Epoxy Resin using Silane Terminated Urethane

In this study, wear properties of toughened epoxy polymer using a silane terminated urethane were investigated. With this aim, epoxy-based hybrid materials with various concentrations were prepared from bisphenol A-type epoxy resin and a silane terminated urethane. It was presented that in addition to a dispersed second phase formation, an interpenetrating network (IPN) structure was also be formed through the addition of silane terminated urethane. Firstly, silane including inorganic part was synthesized from poly(hexamethylene carbonate) diol and 3-isocyanatopropyl trimethoxysilane. The solutions were mixed with epoxy mixture to obtain hybrid solutions. Various hybrid solutions were prepared using different epoxy/inorganic part solution compositions. The effects of IPN on the wear properties of hybrids were investigated.
