Huntsman Advanced Materials (The Woodlands, TX, US) and Huntsman Polyurethanes (Auburn Hills, MI, US) will highlight their advanced epoxy resin and polyurethane systems, specially formulated for cost-effective, rapid production of lightweight, void-free composite parts. Among the specific products Huntsman is offering for building lightweight composite parts are trademarked ARALDITE LY 3585 epoxy resin with ARADUR 3475 hardener, an easy-to-handle, flowable epoxy system wet compression molding. Various curing options are available, with achievable cure times from 1 hour to 65 seconds depending on part size and mold temperature. Composite components compression molded with the epoxy system exhibit high shear and impact strengths and glass transition temperatures in the 230˚F (110˚C) – 260˚F (126˚C) range.
Trademarked VITROX HC 98010 polyol/SUPRASEC 9801 isocyanate is a novel polyurethane system featuring a low, stable initial viscosity with minimal viscosity increase for thorough fiber impregnation during wet compression molding or spray processing. Tunable reaction times and a snap cure make the products ideal for use on large parts, and they impart good properties with strong adhesion to honeycomb core and reinforcement fibers for good impact strength and toughness.
Also at the show will be new trademarked EPIBOND epoxy structural adhesive, a next-generation epoxy for aerospace applications with high peel and shear strengths on a variety of substrates. The new high-performance material is easy to mix and apply, and can be used at temperatures up to 230˚F (110˚C).
