(at 75°F) to maximum 24 hours before coating with specified topcoat.
Important: Test Product #668 Conductive
Epoxy Primer
with ohm meter prior to topcoating to confirm acceptable level of
conductivity is achieved. If test readings are higher than 25,000 ohms,
contact Epoxy.com Technical Support Department for further instructions before installing specified topcoat.
Top Coat with a conductive topcoating like
Product #1ESD, or
Product #630 Conductive.
