Henkel Corp.'s Loctite
E-40EXP is a two-component,
potting compound designed to pass UL testing requirements for
explosion-proof electric motors and maintain more than 85 percent of its compression
strength following exposure to 13 harsh chemicals. Henkel developed this
potting material in anticipation of the 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.
