The Master Bond UV15 offers outstanding light transmission properties and optical clarity for use in bonding, coating and sealing optical assemblies.

This epoxy-based UV-curable system is 100% 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 320-365 nm. It typically cures in thicknesses of a few microns to 0.5mm in 15 to 30 seconds or less. UV15 cures by a cationic reaction and produces bonds that have lower shrinkage (1-2%) and higher temperature resistance than most UV systems. Its glass transition temperature (Tg) is 90-95°C with a straight UV cure. When post cured for 30 minutes at 125°C, the Tg is 125-130°C. The service temperature range for this system is -60 to +177°C. The compound has excellent resistance to a wide variety of chemicals including water, acids, bases, fuels and many solvents. Its low viscosity allows it to be spin coated.
