Description
An adhesive that rapidly cures in situ using ultraviolet radiation. Ultraviolet-cured adhesives were first used in the early 1960s but became more prevalent in the 1980s as technology and equipment improved. These low-viscosity adhesives are composed of a monomer, a low-molecular-weight prepolymer and a photoinitiator. When exposed to UV radiation, the photoinitiators form free radicals that induce polymerization. Cure can be done at low temperatures and in visible but poorly accessible areas. Examples of UV-cured adhesives are some types of silicones, urethanes, and methacrylates. They are often used in the electronic, automotive, and medical fields.
