COMPATIBILITY
CircuitWorks
Conductive E poxy is
generally compatible with m ost m aterials
used in printed circuit board fabrication. As
with a ny a dhesive/sealant, c ompatibility
with substrate should be de termined 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 or der to remove
Electro-Wash or
any sur face c ontamination w hich m ay
prevent adequate material 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 tim es a nd e lectrical
