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.
● If product crystalizes in storage, place container in warm oven until crystallization disappears. Please refer to Tech Tip #7 on website.

Product Description: EPO-TEK® MED-301-2 is a biocompatible, clear and colorless, low viscosity, long pot-life, room temperature
curing epoxy. Additional characteristics are: ease of use in potting and casting, excellent adhesion to glass, quartz, wood and mostplastics. As a compliant, low stress adhesive, it is used in bonding of optics and resistant to impact or vibrations. Used often in
endoscopes and in various imaging systems.
Typical Properties: Cure condition: 45°C / 16 Hours
Different batches, conditions & applications yield differing results.

Biocompatibility Approvals• EPO-TEK® MED-301-2 cured at 45° for 16 hours and 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. While bulk
samples of MED-301-2 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-301-2 for their given application.
• Gamma radiation/ion beam will discolor MED-301-2, thus altering its appearance.
See Technical Tip # 29: Gamma Sterilization for Medical Devices and its Effect on Epoxies for more information.
http://www.epotek.com/site/files/Techtips/pdfs/techtips_29.pdf• MED-301-2 is generally regarded for resisting few cycles of ETO and gamma radiation.
• MED-301-2 can survive more than 500 cycles of liquid disinfection based on glutaraldehyde (3.4% concentration) and more than 500 cycles of peracetic
acid (0.23% concentration) before significant deterioration of the glue joint.

Packaging Availability• EPO-TEK® MED-301-2 is available in specialty packaging such as Pre-Mixed Frozen Syringes (PMF), Bi-Paks, or bulk (A & B containers).
