Vacuum Cast V-825 A/B BJB Enterprises Polyurethane Thermoset Elastomer

Product Description

V-825 A/B is a rigid 84 Shore D polyurethane system that exhibits exceptional physical properties. It is a high performance material that features high heat deflection capability and a low shrink factor. V-825 is a transparent, virtually colorless casting material that allows for unrestricted tinting and precise color matching. This product is ideal for producing intrinsically colored parts requiring a non-painted finish. This product can be easily processed with meter-mix-dispense, pressure or vacuum cast equipment.
