Dixie Chemical (Pasadena, TX, US) is emphasizing its line of anhydride curing agents, reactive diluents, tougheners, resins and bio-based raw materials. Dixie’s line includes modified anhydrides, which combine the performance benefits of specialty additives such as accelerators and mold release agents. Dixie also offers pre-catalyzed anhydride technology, leading to novel anhydride curing agents such as ECA 619 and NMA 419 for epoxy composites. These curatives allow for epoxy formulations with low viscosities, long pot lives, fast cures and high glass transition temperatures (Tg), suitable for high-speed pultrusion processes. Dixie also offers low-viscosity epoxy-anhydride formulations for infusion processes such as resin transfer molding (RTM) and high-pressure RIM. These systems cure at relatively low temperatures, opening up applications like damage-tolerant panels, cured-in-place pipe (CIPP) and electrical castings. Booth U19.

Michael Watkins, senior technical advisor, thermosets, at Dixie, is presenting a technical paper titled “New Pre-Catalyzed Anhydride Curing Agents for High Performance Epoxy Pultrusions” on Oct. 17, 10 a.m. in D221.
