- Application Information
Tecnothane® MDE705Z 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.
Technical Details & Test Data
- Typical Properties
The purpose of the following table is only to provide indicative data about material properties. Typical properties are referred to samples prepared according to internal conditions and measured thirty days after post curing.

*Pot life and demolding time are referred to the system with catalyst TecnoKat D5 as percentage on total amount.- Post Curing Information
Do not allow excessive cooling of molded parts between demolding and post-curing.
Hardness (ShA) Temperature (°C) Time (hours) From 25 to 55 70 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.
