Product Description

Master Bond UV15TK is a high strength, moderate viscosity, epoxy based UV curable system for bonding, sealing and coating. It is 100% reactive and does not contain any solvents or other volatiles. It is also completely free of any oxygen inhibition. UV15TK will cure quickly and easily when exposed to a UV light source with a wavelength range between 320-365 nm, with the optimum at 365 nm. The energy required is typically 20-40 milliwatts per cm². The rate of cure depends upon the distance of the light from the material being cured, the thickness of the section and the intensity of the light source. It typically cures in thicknesses of a few microns to 0.015-0.020 inches in 15-30 seconds or less. Epoxy based UVs are described as having a cationic curing reaction. This kind of system will have lower shrinkage (1-2%) and higher temperature resistance than the majority of UV systems, which cure by a free radical mechanism. UV15TK has excellent resistance to a wide variety of chemicals including water, acids, bases, fuels and many solvents. It features superb physical strength characteristics and electrical insulation properties. UV15TK has superior adhesion to a wide variety of substrates including plastics, glass and many metals. As is typical with UVs, it has excellent optical clarity and light transmission properties.

Cationic systems, such as UV15TK, tend to have much higher temperature resistance than other UV type systems. Its glass transition temperature with a straight UV cure is 100 to 105°C, and when post cured for 60 minutes at 100°C, its Tg is 135-140°C. This post cure also enhances UV15TK’s chemical resistance. The service temperature range for this system is -80°F to +400°F. It is widely used for a variety of applications in the optical, optoelectronic, aerospace and related industries.
