The above properties are typical of a system cured with hardener #B-31
Recommended Hardeners:
B- 31: A rigid, heat cure system with a long pot life, designed for small to large castings.
B-125: A rigid, faster setting version of B-31 with excellent air-release and hardness.
Mixing Instructions:
Weigh the desired amount of CLEAR-1047 resin into a clean container and combine with recommended hardener in one of the ratios shown below.
| Hardener | Parts by Weight per 100 pts. Resin |
Pot Life 100 grams @ 25oC |
| B-31 | 50 | 2-3 Hours |
| B-125 | 45 | 1-2 Hours |
Recommended Cure Schedule
| Hardener | Cure @ 25oC | Cure @ 65oC | Cure @ 100oC | Cure @ 130oC |
| B-31 | — | 1-2 Hours | 1 Hour | 30-45 Minutes |
| B-125 | — | 1 Hour | 30-40 Minutes | 30 Minutes |
