POST CURING:
All physical property results are based upon post-curing this system. The following procedure provides the best results:
150 F (66 C) for 1.5 to 2 hours
250 F (121 C) for 2 hours
300 F (149 C) for 1 hour
350 F (177 C) for 1 hour
Allow to cool in the oven. This procedure provides further stabilization and eliminates possible thermal shocks for cavity tools that are
temporarily clamped together for curing purposes.
STORAGE:
Store at ambient temperatures, 65-80 F (18-27 C). Unopened containers will have a shelf life of 12 months from date of shipment
when properly stored at recommended temperatures. Purge opened containers with dry nitrogen before re-sealing.

SAFETY PRECAUTIONS :
Use in a well-ventilated area. Avoid contact with skin using protective gloves and protective clothing. Repeated or prolonged contact
on the skin may cause an allergic reaction. Eye protection is extremely important. Always use approved safety glasses or goggles
when handling this product.
IF CONTACT OCCURS :
Skin: Immediately wash with soap and water. Remove contaminated clothing and launder before reuse. It is not recommended
to remove resin from skin with solvents. Solvents only increase contact and dry skin. Seek qualified medical attention if
allergic reactions occur.
Eyes: Immediately flush with water for at least 15 minutes. Call a physician.
Ingestion: If swallowed, call a physician immediately. Remove stomach contents by gastric suction or induce vomiting only as
directed by medical personnel. Never give anything by mouth to an unconscious person.
Refer to the Material Safety Data Sheet before using this product.
WARNING: This product can expose you to chemicals including Ethylbenzene and 4,4 -Isopropylidenediphenol, which are known to
the State of California to cause cancer, birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov.

Product Application Procedure for 3D Printed Parts
Material: TC-1614 Epoxy
Purpose of Procedure: To impregnate rigid, porous 3D Printed Parts with epoxy. Infusing epoxy into the surface is a
beneficial procedure to increase strength, improve handling qualities and in some parts, improve aesthetics. Some
systems will absorb more material than others.
Procedure:
Pre-warm A&B material in separate containers to 90 -100 F maximum (32 -37 C max) in a temperature
controlled industrial oven. This will help to lower the viscosity and increase the absorption rate of epoxy into
the part (never use a household oven that may be in contact with food).
You can also pre-warm the 3D printed part to aid in epoxy infiltration. 100 -120 F (37 -49 C) is a good range
but refer to your 3D printed material recommendations for heat resistance in an effort to avoid distortion.
Place a small 3D Printed Part into a self-sealing (zipper lock) plastic bag and fill with an appropriate amount
of epoxy. A bag that is too large will require more volumetric amounts of epoxy. Squeeze out as much of the
extra air in the bag to assure part is fully submerged and coated with epoxy then seal bag.
Allow the part to soak in the epoxy for roughly 20-25 minutes. A recommended optional procedure would be
to place bag with soaking 3D Printed part into 100 -120 F (37 -49 C) oven in a leak-proof, metal container,
and allow to soak for 15-20 minutes. Check part at 5 minute intervals to monitor viscosity levels and for any
exothermic reaction. Larger batches of mixed epoxy will have a shorter reaction time.
Once part has soaked for allotted time, pull part out of bag and drain excess epoxy off of part.
For larger parts, mix enough A&B together so you have sufficient material to brush an even coat over the part.
Continue brushing drips and runs to keep part coated for 20-30 minutes. Then drain off excess epoxy and
wipe down surface with clean, dry paper towels. Avoid using any solvents since it will affect the curing
properties.
*Note that mixing a large mass of epoxy can produce an increase in chemical reaction shortening work time
and increasing exotherm (heat) as it sits. Do not leave a large, concentrated mass of epoxy in a container
unattended. After soaking the part, it may be best to split up a large batch (over 200-300g) by draining the
bag into 2-3 separate small containers and allow to harden.
Hang part with wire over a cup or bucket to allow continued drainage of excess epoxy. Wipe off any areas of
pooled epoxy with a gloved finger or brush. Monitor any sags or drips for the next hour or until epoxy has
gelled.
You can expedite curing of the epoxy in an oven at 100 -120 F (37 -49 C) and promote better physical
properties of the finished material. You can also allow the epoxy to cure at room temperature but an elevated
post cure will achieve the best results.
