At Permabond we are reminded by our friends in the fire protection industry how valuable our weld sealant is to their work. At the last AFSA convention, our team was approached by many contractors and fabricators who stopped by our booth just to say thank you for such a valuable product. So when I glanced at an email that came through from a fire protection contractor – that said Thank you for a great product! I assumed it was another fire protection application of weld sealant that saved them money on call backs for leaks.
However, this contractor had another use for our weld sealant. They had damaged the oil pan of a large piece of equipment. The pan was not removable without significant disassembly of the equipment. The service mechanic elected to try to weld it in place. However, the geometry and the location of the damage made getting a pristine weld very difficult. There was porosity and possible leakage after the weld was completed. Because they were already familiar with using weld sealant in fabrication, they applied Permabond HL126 to the weld. The oil pan is now leak free.
So how does weld sealant work?
Anaerobic sealants such as Permabond HL126 in the Americas and A126 in Europe wick into weld porosities and cure to form a permanent seal. For best results, follow the process below.
