Applications of Radiation-Curable Adhesives

Some typical applications of UV-curable adhesives and sealants are illustrated in Fig. 11. 

Both radical-type and cationic-type UV-curable resins have been used in laminating adhesive applications (acrylates [14,30,31,81], thiol-ene [41,82], 

Recent advances have made radiation-curable laminating adhesives very attractive in terms of economics, automation, quality of adhesive bond and throughput, while offering distinct advantages with respect to both energy consumption and pollution control [4], 

A considerable amount of work has been devoted to the bonding of two elements by means of UV-curable structural adhesives. The two parts of the assembly can be identical (homolaminates) or of a different nature (heterolaminates) and consist either of flexible films such as polyesters, poly(vinyl acetate), nylon, aluminum foils and paper, or rigid transparent plates such as poly(methylmethacrylate).
