- Application Information
Tecnothane® MDE795Z has been developed for performing in demanding and harsh environment which required a non-conventional solvent resistance to swelling, like lacquering rollers or screen-printing application. The system is designed to provide high level mechanical properties combined with excellent grind-ability, and elastic properties allowing size retention after many working cycles.

Pot life and demolding time are referred to the system with the suggested percentage of catalyst on total amount. 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) Lower than 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.
Packaging & Availability
