EPO-TEK® CF6-2
Technical Data Sheet
For Reference OnlyHigh Temperature Epoxy

EPO-TEK® CF6-2 Advantages & Suggested Application Notes:● The low viscosity nature allows for wicking and impregnating into fiber optic bundles,
commonly found in medical or sensor industries.
● Low outgassing nature makes it ideal for high temperature fiber optic environments.
● Suggested Applications:o Sensor Devices: down hole fiber sensors for petro-chemical industries. High power
laser light beam delivery.
o Optics: Spectral Transmission in the VIS and IR region > 600 nm range.
● Amber color change upon cure allows for visual ID inspection of cure.
● Convenient 1:1 mix ratio allows for static mixing, or specialty packaging in double-barrel
syringes.
