Easy to Post-Process

Form Wash Settings:

  • Duration: 6 minutes
  • Notes: Ensure not to exceed 6 minutes in solvent to avoid degrading the final part's quality.

Form Cure Settings:

  • Duration: 120 minutes
  • Temperature: 80°C
  • Notes:
    • High Temp V2 resin offers various post-curing options; refer to the technical data sheet for guidance on how different settings impact mechanical properties.
    • For the maximum HDT of 238°C @ 0.45 MPa:
    1. Cure in Form Cure for 120 minutes at 80°C.
    2. Then, thermally cure in a non-food oven at 160°C for 3 hours.
    • For applications requiring lower heat resistance, a 60-minute cure at 60°C is recommended.

Notes Notes
Do not leave High Temp Resin in solvent
for longer than 6 minutes total, as
excessive solvent exposure affects the
quality of the final part.
There are several post-curing options for
High Temp V2. Refer to the technical data
sheet to understand how different options
affect mechanical properties, and choose
the post-cure option that is best suited to
the intended application. To achieve the
highest HDT of 238 °C @ 0.45 MPa: (1)
Post-cure parts in Form Cure for 120 min
at 80 °C. (2) Thermally post-cure parts in
a non-food oven for 3 hours at 160 °C.

For applications that do not require the
maximum heat resistance, post-cure parts
in Form Cure for 60 min at 60 °C.
