Master Bond EP19LV One Component Epoxy System
Categories: Polymer; Thermoset; Epoxy

Material Notes: Key Features:
  • Low viscosity
  • Impressive durability
  • Unlimited working life at room temperature
  • Superior temperature resistance properties
  • High physical strength profile
  • Excellent electrical insulator
Product Description: Master Bond 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 EP19LV is 100% reactive and does not contain any solvents or diluents, shrinkage upon cure in minimal. Recommended cure conditions are 1.5-2 hours at 300°F (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 resistance properties. 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. EP19LV can be used over the remarkably wide temperature range of -60°F to more than +300°F. It has a shelf life of more than 4 months when stored at 75°F and it can be extended to more than 6 months by storage at 40°F to 50°F.

Product Advantages:

  • Low viscosity assures convenient handling and easy processing
  • Superior thermal stability up to 300°F service
  • Remarkably good chemical resistance to water, inorganic acids, bases, salts and many organic solvents
  • Low odor and toxicity
