Master Bond UV15-7NV-2 is a one component, UV curable polymer system for high performance bonding, sealing, coating and encapsulation. It has good physical strength properties, low shrinkage upon curing and is non-yellowing. This system bonds well to a wide variety of substrates including glass, metals and plastics, such as polycarbonates, acrylics and a number of polyester films. It is 100% reactive and does not contain any solvents or diluents. UV15-7NV-2 offers very good chemical resistance to water, fuels and many solvents. The UV cured polymeric material can be employed over the wide service temperature range of -80°F to +300°F. UV15-7NV-2 exhibits an excellent combination of properties including outstanding toughness, electrical insulation and withstands thermal cycling.
Master Bond UV15-7NV-2 system is not oxygen inhibited and generally cures in 15-45 seconds when exposed to a UV light source emitting at a wavelength of 320-365 nm with an energy output as low as 20-40 milliwatts/cm². The rate of cure depends upon the compound’s distance from the light source, the thickness of the section and the intensity of the light source. It should be noted that the system can cure in sections up to 1/8 inch. However when bonding, sections of a few thousandths of an inch are more than adequate. This system is widely used in optical, fiber-optic, electronic, laser, microelectronic and semiconductor applications.
