TYPICAL VALUES
TRA-BOND FDA-8T EPOXY ADHESIVE is a thixotropic epoxy resin system specifically developed for
bonding applications in accordance with Title 21, U.S. Code of Federal Regulations, Food and Drug
Administration (FDA) Chapter 1, Sub Part B, Sections 175.105 and 175.300. This two-part amber
adhesive is easily mixed, used and cured at room temperature for bonding, laminating and repair
applications by manufacturers of food preparation, processing and packaging equipment, and by
manufacturers of catheters, hearing aids, dental products and other biomedical instruments and
devices. TRA-BOND FDA-8T EPOXY ADHESIVE is an effective electrical insulator, and it provides low
permeability to gases and vapors, and good resistance to water, weather, galvanic action, petroleum
solvents, lubricants and fuels, mild acids and alkalis, and to many other organic and inorganic
compounds.

(1) Carefully clean and dry all surfaces to be bonded.
(2) Remove clamp and thoroughly mix the TRA-BOND FDA-8T epoxy adhesive system components in the handy
BIPAX mixing-dispenser package until color is uniform throughout.
(3) Apply this completely mixed adhesive to the prepared surfaces, and gently press these surfaces together.
Contact pressure is adequate for strong, reliable bonds -- however maintain contact until adhesive is completely cured
Uncured epoxy adhesives - consisting of resin and hardener components - may cause dermatitis, skin sensitization or other allergic responses. Prevent all
contact with skin and eyes. If contact occurs, flush immediately with plenty of water (get prompt medical attention for eyes). Keep away from heat and
open flame. KEEP OUT OF REACH OF CHILDREN. Immediately clean up any spills that may occur.

WARNING: THIS MATERIAL IS SOLD FOR INDUSTRIAL USE ONLY
TRA-CON resin products are marked with an expiration date at the time of manufacture which is similar to the the
dating system used for most perishable materials such as foodstuffs, photographic films, pharmaceuticals and most
reactive products. This date is marked "Use Before" which indicates that the product will yield its best properties
when mixed and cured before the date shown. The expiration date should be monitored to ensure that inventory
levels are replenished in adequate time to avoid unnecessary interruptions in the manufacturing process.
The expiration date is based upon dry storage conditions at or below 80°F (27°C) in the original, sealed and unopened
containers for BIPAX, TRA-PAX and bulk packaged materials. The expiration date for pre-mixed and frozen materials
is based upon dry storage conditions at or below the temperature indicated on each package. Contents may separate
during storage. Resin or hardener in bulk containers (e.g. quarts, gallons) should be thoroughly mixed prior to
combining them to obtain all the benefits of the properties designed into the formulation.
Some ingredients in this formulation provided in BIPAX, TRA-PAX and bulk packaging may crystallize when
subjected to low temperature storage. Merely returning the product back to room temperature will not always
redissolve the crystals and a gentle warming cycle of 125°F for 30 minutes prior to mixing the resin and hardener
components may be necessary to return the product to its best condition. Crystallized epoxy components do not react
as well as liquid components and should be redissolved prior to use for best results.
The properties given are TYPICAL VALUES and are not intended for use in preparing specifications.
Users should make their own tests to determine the suitability of this product for their own purposes.
TRA-CON, INC. MAKES NO EXPRESS OR IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS OR OTHERWISE with respect to its
