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.

USAGE INSTRUCTIONS

Read MSDS carefully prior to use.

Cleaning: For best results, clean the board



with one of Chemtronics



Pow-R-Wash

cleaners in order to remove

Electro-Wash or

any surface contamination which may
prevent adequate m aterial contact.

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
