1 Minute™ Epoxy
Weld porosity's caused seeping oil leaks from this substation transformer. The past repair procedure was to drain the oil from the tank and re-weld. This repair process was expensive and caused long term power outages.
Repair or leak areas were roughened using a grinder. One Minute Epoxy was applied using the Mark 5 Auto Mix System to plug all active leaks. Following confirmation that all oil leaks had been stopped, repair areas were then chemically cleaned using Cleaner Blend 300. Fasmetal was then applied directly over the One Minute Epoxy to a thickness of 1/4, extending beyond the One Minute Epoxy by 3mm. Following Fasmetal's 1 hour cure, repair areas were primed using both FL10 and FL20 Primers. Each primer was allowed to cure or dry for 15 minutes. Using both primers on metal substrates will improve adhesion from 25 pli to 50 pli. Two primer system is always recommended in wet or outdoor operating conditions. Flexane 80 Putty was applied over the Fasmetal to a thickness of 1/4" extending beyond by 3 inches.. Flexane 80 Putty encapsulated the repair area as a flexible, (350% elongation), vibration and climate resistant permanent seal.
