New Epoxy Adhesive for Explosion-proof and Dust-Ignition-Proof Equipment

Posted on 11/12/2018 8:11:56 AM By ASC

MasterBond recently introduced its Master Bond EP41S-6 two-component epoxy which meets UL1203 requirements for use in explosion-proof and dust-ignition-proof electrical equipment used in hazardous locations. The adhesive underwent extensive testing including exposure to a range of flammable chemical vapors. Samples were then examined for any signs of degradation or physical changes as well as being subjected to a crush test.

Following these tests, it was concluded that the epoxy would be suitable for use in flammable conditions associated with gases such as acetylene, hydrogen, propane, and ethylene as well as those in which combustible dusts are present. These included metal dusts, non-conductive dusts, and carbonaceous dusts.

The company reports that the new epoxy adhesive offers thermal stability and tolerates operating conditions at temperatures ranging from -80°F to +500°F [-62°C to +260°C]. Its dielectric strength is 440 volts/mil at 75°F for a 0.125-inch thickness and its mixed viscosity was recorded as being 30,000-40,000 cps at 75°F, making it suitable as a sealing or potting compound.
