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.
