This document discusses advanced materials and composites tooling solutions from Huntsman. It begins with an overview of the design and manufacturing process from design models to master models to composite tools. It then discusses various RenShape board materials and RenPaste seamless modeling pastes that can be used to create design and master models. Several epoxy resin systems for composite tooling like RenLam, Ren, and RenGel are also highlighted. New developments in infusion resins with long pot life and high heat resistance are introduced. The document concludes with a case study of an Araldite solution used to create large composite molds for Airbus aircraft.
