Tecnothane® MPT115G has been developed to be an all-purpose system for high-demanding applications operating at low temperature, underwater, or under hydrolytic environments. It excels in elasticity and dynamic properties, with a good balance of mechanical properties. It fits well with many different tough applications like wheels, technical parts, skating, and offshore. “G” series is designed for improved abrasion resistance.

*Pot life and demolding time are referred to the system with catalyst quantity as above, 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 65 to 74 70 16 From 75 to 92 90 16 Higher than 93 110 16 For hardness above 93 ShA the best performance is obtained through 2 annealing steps. In this sense it is recommended to let the material cool down to room temperature in between the 2 post curing processes.
