Master Bond Polymer System EP19LV 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 EP19LV 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 EP19LV 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 EP19LV 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.
