*Pot life and demolding time are referred to the system without catalyst, TecnoKat D5 can be used to adjust pot life and demolding time.- Post Curing Information
Do not allow excessive cooling of molded parts between demolding and post-curing.
Hardness (ShA) Temperature (°C) Time (hours) From 55 to 74 70 16 Higher than 75 90 16 For hardness ≤ 78 ShA it is recommended to wait 24 h at room temperature before the post-curing cycle.
For hardness above 93 ShA, two annealing steps are recommended to quickly reach the best performances; let the material cool down to room temperature in between the 2 post curing processes.
