EP35AOLV Two-Component, Thermal, Isolating Epoxy
Description
EP35AOLV is a two-part heat-cured epoxy system, designed for bonding, sealing, coating, and potting applications. It's a thermally conductive, electrically insulating compound that withstands aggressive chemicals, such as those found in oil & gas processing. EP35AOLV exhibits protection against corrosion in various harsh environments and helps prolong the longevity of critical equipment. With a service range that extends from -60 to 500°F (52 to 260°C) and a glass transition temperature of around 165 to 170°C, it is resistant to high temperatures.
The thermal conductivity value for EP35AOLV is 7-8 BTU•in/(ft2 •hr•°F) [1-1.15 W/(m•K)], and its compressive strength measures 24,000 to 26,000 psi. It's a filled system that has good dimensional stability and low shrinkage upon curing. Additionally, it has a high tensile modulus of more than 1,000,000 psi at 75°F.
The ideal cure schedule is 2 to 3 hours at 300°F, followed by 3 to 4 hours at 300 to 350°F. EP35AOLV has a forgiving 100 to 50 mix ratio by weight, and is flowable, with a mixed viscosity of 50,000 to 90,000 cps. It adheres well to a wide variety of substrates such as metals, composites, glass, and high-temperature plastics such as PEEK. EP35AOLV is available in standard packaging from ounce kits to gallon kits.
