The PLASTICAST® PT investment & binder kit was designed for the investing and burnout of commonly used plastic or wax/plastic pattern materials. The high expansion of these pattern materials requires an equally high expanding, extra high strength investment. This kit provides jewelry casters with a mold material that meets those demands while maintaining mold surface and dimensional integrity for high temperature metal casting. It can also be used with standard wax patterns for high temperature metal casting. In addition to excellent performance with rapid prototype pattern materials, this kit offers casters the following benefits over traditional two-part platinum investments: Eliminates the acid-based binder hazard associated with common two-part platinum investments. Operators are not exposed to a hazardous liquid. Storage for hazardous liquid is eliminated. Shipping costs and special transportation requirements for hazardous liquid are eliminated. Eliminates special investing flask preparation requirements. Costs associated with absorbent liners are eliminated as they are not needed. Time associated with complicated flask preparation is eliminated.
