Master Bond Polymer System UV15-7SP4 is a one component, low viscosity UV system with superb flexibility. It is 100% reactive and does not contain any solvents or diluents. UV15-7SP4 has very little shrinkage when curing and is noteworthy for retaining its non-yellowing properties. It bonds well to a wide variety of substrates including glass, metals and plastics, such as polycarbonates, acrylics and a number of films. UV15-7SP-4 offers excellent chemical resistance to water, fuels, acids and bases. The UV cured polymeric material can be employed over the wide service temperature range of -80°F to +250°F. Most importantly, the exceptional flexibility of UV15-7SP4 allows it to be used in applications involving rigorous thermal cycling as well as mechanical and thermal shock.
Master Bond UV15-7SP4 system is not oxygen inhibited and cures readily in 10-30 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 of course the intensity of the light source. It should be noted that the system can cure in sections approaching 1/4 inch thick. 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.
