Field Application Reports Products: Application Date: Customer: Industry: Location 98 Transformer Oil Leak Repair Flexane® 80 Putty 4/22/96 B.C. Hydro Utility Power Distribution Problem: Over several years of service, existing caulking sealant would harden and crack compromising the seals on this Step Down Transformer Tap Changer. Water and moisture would seep into the transformer causing a catastrophic failure, often exploding. Step Down Transformer replacement cost was $8K. Solution: Seal areas were roughened to remove existing caulking material and paint. Repair areas were then chemically cleaned using Cleaner Blend 300. Both FL10 and FL20 Primers were applied and each allowed to cure or dry for 15 minutes. Using both primers will improve Flexane adhesion from 25 pli to 50 pli. Two primer system is always recommended for metal substrates in wet or outdoor operating conditions. Flexane 80 Putty was applied and smoothed forming a new seal. Flexane 80 Putty will remain flexible, (350% elongation), while providing a vibration and climate resistant seal. GoJo hand cleaner was used to smooth and sculpt Flexane 80 Putty following gel point. Re-sealing cost using Devcon materials totaled $250.
