Among the new products unveiled by Momentive Performance Materials Inc. (Columbus, Ohio), the resin manufacturer formerly known as Hexion, was a new line of epoxy resin systems for wind turbine blades. EPIKOTE MGS RIMR 145 is an epoxy infusion system for carbon fiber, with low viscosity and long out-time for large blades and low exotherm for thicker laminates. The company reports that the resin is significantly stronger than industry standards and can be used with glass laminates as well. A companion product, EPIKOTE MGS BPR 435, is a new paste adhesive with four times the fatigue performance of the company’s former brand. Its improved rheology and faster cure rate decrease blade cycle time, and its lower density helps reduce overall blade weight and cost. Also new is EPIKOTE Resin 05475 teamed with EPIKURE Curing Agent 05443. Together they enable direct infusion of carbon fiber material with large-scale, high- or low-pressure resin transfer molding (RTM) equipment for automotive structural parts. The automotive resin system reportedly cures in less than five minutes.
