Technical Data Sheet
For Reference Only
Electrically Conductive Epoxy

EPO-TEK® N20E Advantages & Suggested Application Notes:● Pot life of more than one day allows for mass production and minimal waste.
● Suggested Applications:o PCB / Electronics: EMI and Rf shielding of RF and Microwave devices.
o Opto-electronics: IR, digital imaging, and sensor device interconnects.
● Versatility in cure allows for low temperature, box oven, SMT tunnel oven, hand held, orsnap curing techniques to be realized● Thixotropic nature allows for deposition methods like dispensing, screen printing,stamping, or other patterning techniques.
