  • Coal Tar Epoxy TM TECHNICAL DATA

    Mix Coal Tar epoxy base with the Coal Tar curing agent. The mixing ratio is 1/1 (base/curing agent) by volume or 1/0.87 by weight. Coal Tar Epoxy does not require a 'sweat-in' or induction time (induction time is typical of lesser quality epoxies). The mixed components should be used immediately. Potlife is approximately 25-40 minutes at 75°F, so mix only the amount of epoxy that can be easily applied
