● 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

EPO-TEK® 330
Technical Data Sheet
For Reference Only
Low Viscosity Optical Epoxy

EPO-TEK® 330 Advantages & Suggested Application Notes:● Built in color change from clear to amber when cured properly. The color change can beused for in-line inspection of epoxy joints and adhesive fillet.
● Unfilled epoxy resin allows for % transmission in the VIS and NIR.
● Low viscosity allows for wicking and capillary action● Suggested Applications:o Semiconductor: capillary flow underfill for Flip Chip mounted dieo Fiber Optic: polarizing maintaining fibers (PMF) found in gyroscope coils; fiber
termination into ferrule.
