The amount of main components is given on parts by weight.
*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.
A first annealing step of 16 hours at 90 °C is recommended.

Hardness (ShA) Temperature (°C) Time (hours)
Lower than 78 100 16
Higher than 78 110 16

Two annealing steps are recommended to quickly reach the best performances; let the material cool down to room temperature in between the post curing processes.

Packaging Information
Materials are available in following packaging: 25, 50 or 200 kg

Storage & Handling

Handling Information
  • In order to allow complete melting, pre-heat materials at following conditions (melting times are referred to 200 kg drums,stored at 20°C)
Pre-heating temperature (°C) 75
Pre-heating time (hours) 24
  • After pre-heating, make sure all materials are completely melted.
  • Well mix melted material by drilling or rolling the drum
  • Load materials to the machine immediately after mixing.
  • Materials must be stored under nitrogen blanket after use.
