Master Bond Polymer System EP19HTLV is a storage stable one component liquid epoxy resin system for durable, high performance adhesive/sealants, impregnants and liners. It feature remarkably long shelf life and excellent storage characteristics at ambient temperatures yet cures readily at elevated temperatures to a tough, strong and chemically resistant thermoset plastic. Low viscosity facilitates handling at ambient temperatures and is particularly desirable for impregnation applications. As Master Bond Polymer System EP19HTLV is 100% reactive and does not contain any solvents or diluents, shrinkage upon cure in minimal. Recommended cure conditions are 1½-2 hours at 300° (150°C), less at higher temperatures. The cured material has high physical strength properties (tensile strength more than 10,000 psi), is thermally stable (heat deflection temperature more than 280°F) and has superior electrical insulation properties (volume resistivity greater than 1015 ohm cm) as well as remarkably good chemical resistant properties. Master Bond Polymer System EP19HTLV is widely used in the mechanical and in the electrical/electronic industries as an adhesive/sealant, impregnant for porous metals and nonmetals and as a high strength, chemically resistant liner. The Master Bond Polymer System EP19HTLV can be used over the remarkably wide temperature range of -60°F to more than +300°F. The Master Bond Polymer System EP19LV has a shelf life of more than 4 months when stored at 75°F. The shelf life can be extended to more than 6 months by storage at 40°F to 50°F.
