Kast Series Urethane Resins

Kast Series products are high-performance, fast-cast tooling and casting urethane resins.
Kast Series products are two-part, room-temperature curing (RTV) systems designed for use in a variety of applications including foundry, special effects, prototyping, vacuum and thermo-forming, and many other industrial and commercial applications.
Kast products were developed to provide high moisture resistance, improved filler suspension, easier premixing of the components, and minimal shrinkage.

Product | Description | Shore Hardness | Mixed Viscosity | Mix Ratio by Weight or Volume | Pot Life | Demold Time* | Color |
BC-8002 Kwik-Kast II Gray | High-performance urethane tooling and casting resin with a fast turnaround time. | D85 | 2,350 cP | 1A:1B | 5-6 min. | 1-2 hr. | Gray |
BC-8655 Kwik-Kast II Blue | Similar to BC-8002, but blue in color and with a slightly longer pot life. | D83 | 2,120 cP | 1A:1B | 8-10 min. | 1-2 hr. | Blue |
BC-8009 Slo-Kast Gray | Features a longer pot life compared to BC-8655 and BC-8002 - ideal for filling larger closed mold cavities and casting large sections without having to stage pour. | D85 | 2,250 cP | 1A:1B | 14-18 min. | 3-4 hr. | Gray |
BC-8010 Metal-Kast | Simulates many of the desirable characteristics of aluminum metal. | D83 | 2,250 cP | 1A:1B | 6-7 min. | 1.5-2 hr. | Gray |
