New Potting Material Withstands Exposure To Harsh Chemicals

Loctite epoxy potting compound meets requirements for explosion proof motors

Rocky Hill, CT — To help manufacturers comply with UL-674 requirements for explosion-proof electric motors, Henkel Corporation has introduced Loctite E-40EXP, a two-component, room-temperature-curing epoxy potting compound designed to pass UL testing and maintain more than 85% of its compression strength following exposure to 13 harsh chemicals. Henkel developed this new potting material in anticipation of the December 11, 2010, implementation of revised UL-674 requirements for potting and sealing compounds used in hazardous locations.

Used to pot and seal wire conduits, Loctite E-40EXP isolates the electric motor from hazardous vapors and chemicals that could cause an explosion. Clean and fast-curing, Loctite E-40EXP can be used in any size fitting, potting or sealing application. The material will not expand and experiences very little shrinkage, facilitating accurate dispensing.

Loctite E-40EXP is available either in user-friendly 2:1 static mix cartridges for easy dispensing or in bulk for high volume applications. This material cures in approximately 2 hours at room temperature and contains no carcinogens, ensuring worker safety.

In addition to motor applications, Loctite E-40EXP is suitable for assembling or repairing pumps, fans, lighting, electrical connectors, sensors, and probes, or whenever chemical resistance or explosion-proof seals are required.
