•
The resin can be cured at an accelerated rate in an oven. The oven must be vented. Ventilation
designs need to meet each customer’s respective governmental health and safety requirements. A
reference frequently used by U.S. firms to comply with OSHA regulations is the American Conference of
Governmental Industrial Hygienists Industrial Ventilation Manual. At 160
°
F (71
°
C) your part will reach
full strength in 2 hours.
•
Allow the part to cure for 1 hour at ambient temperature prior to placing in the oven for accelerated cure
to avoid discoloration due to exothermic reaction.
•
The part should be placed on a non-stick, (wax paper, Teflon, etc.) material or it will adhere to the
surface it is sitting on while curing.
•
Wear gloves when handling the parts when they are still at an elevated temperature. Parts will attain full
strength and be safe to handle once they cool to room temperature.
•
The resin will cure at room temperature after 24 hours.

• Parts can be painted to enhance surface finish and appearance. Z Corp recommends coating all
surfaces with Dupont Fill ‘N Sand Acrylic Primer-Surfacer #131S, a lacquer-based primer ideal for improving
the adhesion of most paints. This material can be purchased at most auto body supply stores.
