COMPATIBILITY
CircuitWorks Conductive Epoxy is
generally compatible with most materials
used in printed circuit board fabrication. As
with any adhesive/sealant, compatibility
with substrate should be determined on a
non-critical area prior to use.

Cleaning: For best results, clean the board
with one of Chemtronics Electro-Wash or
Pow-R-Wash cleaners in order to remove
any surface contamination which may
prevent adequate material contact.
NOTE:
Mixing: Mix equal amounts (1:1) by
weight or volume of Part A and Part B. Mix
thoroughly for 2 minutes and apply within 8
minutes.
Thinning: Do not attempt to thin.
Curing:
Curing times and electrical
conductivity
depend
primarily
on
temperature.
For fastest curing times,
maximum conductivity and adhesion, cure
the bond between 150-250°F (65-121°C) for
5-10 minutes. CircuitWorks Conductive
Epoxy can be room temperature cured at or
above 75°F (25°C), for 4 hours. Maximum
conductivity and bond strength are achieved
in 24 hours. Curing at temperatures below
75°F (25°C) will result in a loss of
conductivity and adhesion.
Pot Life: 8-10 Minutes at 75°F (25°C) after
mixing.
