Epoxy-based UV-curable system with high temperature resistance
With its excellent light transmission properties and optical clarity, Master Bond UV15 is widely used for a variety of bonding, coating and sealing applications in the optical, electronic and optoelectronic industries. This epoxy-based UV curable system is 100 per cent reactive and does not contain any solvents or other volatiles. It is also completely free of any oxygen inhibition.
Like most UV systems, Master Bond UV15 will cure quickly and easily when exposed to a UV light source with a wavelength range between 320-365nm. It typically cures in thicknesses of a few microns to 0.015-0.020 inches in 15-30s or less. UV15 cures by a cationic reaction and produces bonds that have lower shrinkage (1-2 per cent) and higher temperature resistance than most UV systems. Its glass transition temperature (Tg) is 90-95degC with a straight UV cure. When post-cured for 30min at 125degC, the Tg is 125-130degC. The service temperature range for this system is -80degF to +350degF.
UV15 has excellent resistance to a wide variety of chemicals including water, acids, bases, fuels and many solvents. It features excellent physical strength characteristics and electrical insulation properties. UV15's low viscosity allows it to be spin coated. It has superior adhesion to a wide variety of substrates including plastics, glass and many metals. UV15 is available in syringes, ½ pints, pints, quarts, gallons and 5 gallon containers.
Featuring high dielectric strength, low dielectric constants and high volume resistivity Master Bond UV15 offers superior electrical insulation properties.
