The amount of main components is given on parts by weight.
*Pot life and demolding time are referred to the system without catalyst, Tecnovat 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 65 to 74 70 16
Higher than 75 90 16

For hardness ≤ 78 ShA it is recommended to wait 24 h at room temperature, before 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.
