Compression test load (N) Vs deformation (mm)
Fatigue test: 500,000 cycles at 1,5Hz frequency with deformation between 0 and 69%
Deformation at cycle end: 5% (ref. NDI-foam 3%)- Casting Information
Density (g/cm³) MPT450MX RH300MX Catalyst (%) Molds T (°C) Cream time (sec) Demolding (min) * 100.00 10.33 ** 50 5-7 10-12 The amount of main components is given on parts by weight.
*When casting car shock absorbers, it is necessary to keep a 10% higher density than the one required with an NDI-based system.
**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.
Cycle Temperature (°C) Time (hours) 1 70 16 It is recommended to wait 24 h at room temperature before the post-curing cycle.
Packaging & Availability

- Storage Information
Materials are available in following packaging: 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) 70 Pre-heating time (hours) 24 - After pre-heating, make sure all materials are completely melted.
- Add water to RH300MX in the quantity specified on the label of the material.
- 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.
