New Momentive Specialty Chemicals Inc. Technology Enables Mass Production of Class-A Composite Parts

Friday 19. April 2013 - A broader range of composite products for automotive Class-A production is now available from Momentive Specialty Chemicals Inc. ("Momentive Specialty Chemicals" or the "Company"). A new generation of epoxy resin transfer molding (RTM) systems is available in EPIKOTE binder 04695-1 and EPIKURE 05490A curing agent.

The new products deliver a minimum level of cure shrinkage. This characteristic paired with optimized RTM and HP-RTM process conditions, allows the production of high surface quality composite components that meet the automotive Class-A surface quality standard, and helps to substantially reduce the cost of light-weight composites.
“This new resin system is specifically suitable for gap impregnation RTM processing. The excellent surface quality is the result of very low shrinkage during curing, combined with a higher glass transition temperature (Tg), which prevent damage during the de-molding step,” says Dr. Tareq Hasson, R&D manager composites. “This system cures in less than 15 minutes at 90°C with gap RTM, and it can also be used with standard RTM processes. It expands our portfolio for Automotive Class-A composites, which now includes a higher Tg faster curing alternative to the widely used EPIKOTE Resin 04695-1 and EPIKURE Curing Agent 05357 system.”
