  • 1. Aerospace_Insert-VacuumCore 2/26/10 10:50 AM Page 1 Advanced Materials Vacuum Reinforcement of Honeycomb Core with Huntsman Frozen Syntactic Products Epocast® frozen epoxy syntactic patties from Huntsman are ideal for fast, complete filling of honeycomb cavities using a standard vacuum bag process. This vacuum core-reinforcing method increases fabricating productivity and improves the quality and structural integrity of honeycomb composite parts such as engine nacelle sections and aircraft acoustical panels. Huntsman produces four frozen one-component syntactic materials: Epocast® 938-A2 epoxy, Epocast® 1614-A1 epoxy, Epocast® 1627 epoxy and Epocast® 1661 epoxy. Each of the products is formulated for easy handling; patties are ready to use after a room temperature thaw. The softened syntactics can be used to effectively reinforce even small, 1/8-inch cell sizes. Huntsman frozen epoxy patties are high- performance materials with physical characteristics such as: Qualified to Boeing and other OEM specifications Long, 8 – 24 hour work lives Excellent high-temperature performance High compressive strength
