EP19HT adhesive/sealant

The EP19HT adhesive/sealant is a storage-stable, single-component, low-viscosity system that cures readily at elevated temperatures to a tough, chemical-resistant, clear amber thermoset plastic. It contains no solvents or diluents, and cures in 1 h at 250°F; cure time can be reduced by raising the temperature to 325–350_ F. The material has a viscosity of 500–600 cP at 75°F, a volume resistivity of more than 1,015 O-cm, a tensile strength exceeding 10,000 psi, and a heat deflection temperature of more than 280_ F. With a service operating temperature range of –60°F to 400°F and excellent resistance to water, inorganic acids, bases, salts and many organic solvents, it is suitable for use as an adhesive in electronic/electrical applications, as a chemically resistant liner, and in providing sealing porosity in graphite.
