Henkel Engineer Provides Solution after Analyzing Process Considerations

A multinational customer manufactures high voltage integral horse power motors of 150 to 3000 HP rating in India. Customer used a rtv silicoone sealant to seal the end shield of the motor. However, the seal failed to perform consistently and failed to withstand IP 65* tests. During a plant survey, Henkel Application Engineer analyzed that the operator takes close to 15 min to dispense the silicone on the flange area, by which time the silicone would have started to skin over this leads to insufficient bonding on the mating flanges and improper sealing.

The high voltage IHP motors of 150 to 3000 HP rating in India used an RTV silicone sealant to seal the end shield of the motors. However, the seal created by this sealant failed to perform consistently and failed to withstand IP 65* tests. During a plant survey, Henkel Loctite 518 Gasket Eliminator an anaerobic Flange sealant was recommended for this application. It fills all imperfections of cast iron body and end shield. It does not cure until the application on the entire flange area is complete and end shield is assembled thereby eliminating the limitations with previous application method. The assembly passes IP 65 test - eliminating rejections and rework.
