EB application in pressure sensitive adhesives

Two kinds of pressure sensitive adhesives (PSA's), that were formulations of radiation cross-linkable styrene-isoprene block copolymer (SIS) and complete hydrogenated aliphatic tackifying resin or non-hydrogenated, were prepared and the electron beam (EB) irradiation effect on these PSA performances such as peel strength against some kinds of adherends was studied. The results from measuring of PSA performance exhibit the close correlation between EB irradiation effect of these and the miscibility of the tackifying resin against SIS. Further it was clarified that PSA performance was influenced by the surface tension of adherends
