Product Description
CONATHANE UC-43 is an unfilled, two-component, 100% solids urethane casting system that cures at room or elevated temperatures. Developed for producing tough, dimensionally stable castings, it is commonly used in prototyping applications requiring a thermoplastic-like feel and appearance. The material combines a low initial mixed viscosity of approximately 1,000 cP with a 15-minute work life, supporting casting and potting operations. After cure, it provides high hardness, strong mechanical properties, and good machinability, making it suitable for prototype parts and other impact-resistant cast components.
Key features
- High-impact casting material: Formulated to produce tough, dimensionally stable castings with high impact resistance.
- Flexible curing options: Can be cured for 7 days at 25°C or accelerated to 16 hours at 80°C.
- Machinable cured system: Produces rigid cast parts with Shore D 85 hardness and good post-processing capability.
Applications / Suitable for
- Prototype castings requiring a thermoplastic-like feel and appearance
- Bench potting and casting operations
- Meter-mix potting and casting processes
- Vacuum potting and casting applications
- High-impact-resistant cast components
