URACAST™ UC-2350
- Chemical Family
- Urethanes
UC-2350 is a two-part urethane resin system, which combines good handling characteristics with excellent cured properties. Its low viscosity allows for easy flow and air release and excellent hydrolytic stability. The cured elastomer has excellent water resistance and is exceptionally resistant to thermal shock.

- Warning
Although the system contains low volatility materials, care should be taken in handling. Adequate ventilation of work place and ovens is essential. For eyes, flush immediately with plenty of water for at least 10 minutes and seek medical attention.
- Shelf LIfe
The shelf life of these materials is six months when stored in unopened containers at an average temperature of 25°C. If containers are opened and the contents only partially used, the container should be flushed with dry nitrogen before being resealed.. Once opened, store in 20-25°C temperatures in dry environment. Common urethanes are moisture sensitive which can lead to altered behavior and performance.
- Technology
- Ready-to-Use Products
- Use instructions
1. To each 100 grams of Part B, add 45 grams of Part A and mix it well preferably using a mechanical mixer. 2. Vacuum degas for about 3-4 minutes to remove any dissolved or entrapped air. 3. Proceed with the casting or potting application and cure as recommended.. These materials are intended for industrial use only, and the practices of good housekeeping, safety and cleanliness should be followed before, during and after use.
