Additives in radiation (EB/UV) cured adhesive formulations

SpecialChem / Oct 14, 2002

Radiation curing is a production technique for polymerizing and curing of adhesives through the use of radiant energy. The source of the radiant energy is generally electron beam (EB), ultraviolet (UV) light, or visible light. These forms of radiation have the energy necessary to initiate polymerization of low molecular weight, unsaturated resins. This paper will generally describe the radiation curing process and provide the requirements of adhesive composition. Polymeric inks, coatings, adhesives, or similar products can be dried or cured with radiant energy. Examples of adhesive applications include: * Pressure sensitive labels and decals; * Laminating adhesives; * Fastening, potting, and encapsulation of electrical / electronic components; * Dental fillings; * The assembly of medical components and consumer products. One of the most popular uses of radiant curing is the advancement or curing of pressure sensitive adhesives. Radiation curing permits the use of solvent-free adhesive compositions.
