| TC-866 A/B is a medium viscosity, economical and easy to handle two component urethane compound. This system cures relatively fast at room temperature producing tough, impact resistant castings. TC-866 A/B is recommended in applications where a resilient surface hardness is desired while maintaining good flexibility. |

| Additional Information |
|---|
| Most of the physical properties can be achieved in 5-7 days at ambient temperature, 77°F (25°C). In order to achieve maximum physical properties, a post cure with heat is required. BJB recommends 24 hours at ambient temperature, 77°F (25°C), followed by 16 hours at 160°F (71°C). |
