Overview of Ultraviolet Light Curable Pressure Sensitive Adhesives, PSAs, 2000 Hot Melt Symposium Proceedings
Mark Mitry, Paula Bushendorf--Ultraviolet light curable adhesives function as the solution to various adhesive problems. These products offer; fast cure speed, higher heat resistance, ease of application, and environmental benefits. Numerous publications and market surveys have discussed the various economics benefits of radiation curable products (1-5).
This paper will discuss the free radical and cationic photopolymerizations of PSAs. Variables such as cure speed; UV light intensity, curing in inert atmosphere will also be discussed. The impact of several commercially available tackifiers on free radical photopolymerization will be presented in some details.
