Featuring breakthrough LED curing technology, LED401LV will cure completely tack-free when exposed to a light source emitting 405 nm wavelength in sections of 1/8 inch thick and beyond. Once cured, it has impressive physical properties, including outstanding dimensional stability, very good electrical insulation, optical clarity and commendable chemical resistance. Since LED light sources do not generate as much heat as UV ones, LED401LV can be used to bond heat sensitive substrates.
