NOTES:● Container(s) should be kept closed when not in use.
● Filled systems should be stirred thoroughly before mixing and prior to use.
● Performance properties (rheology, conductivity, others) of the product may vary from those stated on the data sheet when bi-pak/syringe packaging or
post-processing of any kind is performed. Epoxy’s warranties shall not apply to any products that have been reprocessed or repackaged from Epoxy’s
delivered status/container into any other containers of any kind, including but not limited to syringes, bi-paks, cartridges, pouches, tubes, capsules, films
or other packages.
● Syringe packaging will impact initial viscosity and effective pot life, potentially beyond stated parameters.
● TOTAL MASS SHOULD NOT EXCEED 25 GRAMS● Component suppliers assure Epoxy that all components are supplied in compliance with ISO 22442. Sales of EPO-TEK ® MED-353ND-T shallaccordingly require Epoxy’s Standard Specification document to be signed as a technical agreement thereunder.

Product Description: EPO-TEK® MED-353ND-T is a biocompatible, thixotropic formulated version of EPO-TEK® MED-353ND. It has
non-flowing properties (paste/non- sagging) and high temperature resistance. Some additional characteristics are: built-in color change
in curing, and high strength. It is design in many medical devices where a high strength, non- flow adhesive is desired.
Typical Properties: Cure condition: 150°C / 1.5 Hours
Different batches, conditions & applications yield differing results.

Biocompatibility Approvals• EPO-TEK® MED-353ND-T cured at 150° for 1 hour has been tested and is ISO 10993 certified, meeting Hemolysis (10993-4),
Cytotoxicity (10993-5), Implantation (10993-6), Intracutaneous (10993-10), Sensitization (10993-10) and Systemic Toxicity (10993-11) test protocols.

Sterilization Information• Epoxy performance is most influenced by surface preparation and cleanliness, overall process and handling, and finally proper curing selection. Whilebulk samples of MED-353ND-T may resist sterilization technologies such as autoclave steam, gaseous technologies, gamma radiation as well as liquid
disinfectants, the glue joints may differ. All users need to determine the suitability of MED-353ND-T for their given application.
• MED-353ND-T is generally capable of resisting hundreds of autoclave and Sterrad® sterilization cycles.
• MED-353ND-T is generally regarded for resisting few cycles of ETO and gamma radiation.

Packaging Availability• EPO-TEK® MED-353ND-T is available in specialty packaging such as Pre-Mixed Frozen Syringes (PMF), Bi-Paks, or bulk (A & B containers).
