HACKENSACK, N.J., March 14, 2013 — Master Bond Inc.’s UV25 offers a one-part, no-mix system and rapid cures upon exposure to UV light. It features high temperature resistance and optical clarity with high light transmission properties.
With its thermal stability and glass transition temperature of 186 °C, it is serviceable from –60 °F to 500 °F. When exposed to UV light emitting at 320 to 365 nm with an energy output of 20 to 40 mW/cm², it cures in 20 to 30 s, depending upon the compound’s distance from the light source, the thickness of the section and the intensity of the light source. The adhesive bonds well to glass, surface-treated metals and plastics including polycarbonates and acrylics.
When used in potting applications, UV25 can cure in sections up to 0.100 to 0.120 in. At room temperature, it has a moderate viscosity of 7000 to 11,000 cps. It is also a competent electrical insulator.
The system is suitable for bonding, sealing, coating and encapsulation applications for the aerospace, fiber optic, optical, electronic and related industries.
It is available in syringes, ½-pint, pint, quart, gallon and 5-gallon containers.
