High-Performance Casting & Molding Rubber Parts

The TrueCast XL products are a line of liquid polyurethane resins that are specifically formulated to create extremely durable, high strength rubber parts. The TrueCast XL Series is processed at room temperature conditions (72 F). Parts cure to full strength without the need for post-curing ovens. In addition, these polymers are formulated with low viscosities and convenient mix ratios by volume for easy machine dispensing or hand mixing.
