QUESTIONS & ANSWERS

The cure time of the high-temperature epoxy coating, Belzona 1523 varies on the ambient temperature condition. The cure time is as follows:
Ambient temperature Time until inspection Time until full service Time until post-cure (if required)
Dry Wet
50°F/ 10°C 45 hours 7 days 45 hours 85 hours
68°F/ 20°C 11 hours 25 hours 11 hours 18 hours
86°F/ 30°C 7 hours 14 hours 7 hours 10 hours
104°F/ 40°C 4 hours 9 hours 4 hours 6 hours
Post-cure will generally be unnecessary as the coating will cure sufficiently at ambient temperature; however, post-cure is possible if desired for a quicker return to service. The coating should be heated between 122°F/ 50°C and 212°F/ 100°C for a minimum of 1 hour. For more information, see the Instructions for Use (IFU): Belzona 1523
