All the formulations used in our experiments utilized a diacrylated Bisphenol A epoxy, Novacure 3700 (Interez, Inc.), as the base resin. Four multifunctional acrylates were used to modify cure behavior and physical properties. They were< trimethylolpropane triacrylate (TMPTA), polybutanediol diacrylate (PBDDA), pentaerythritol triacrylate (FETA) and dipentaerythritol triacrylate (DPBPA). The base resin, TMPTA and PETA were supplied by Interez, Inc. PBDDA was obtained from Alcolac Chemical. DPEPA was supplied by Sartomer. All were commercial grades, and were used without further purification. The photoinitiator used for all experiments was Darocur 1664 (EM Industries), a mixture of aromatic Icetones whose absorption s ctrum is shown in Figure 2. It was chosen because it is well-matched to the emission spectrum of the Fusion "V" lamp which was used as the source of irradiation. The formulations used are summarized in Table I.

Sometimes, other diluents that are not acrylic esters, like vinyl pyrrolidone, are also used. The triacrylate esters may be compounds, like pentaerythritol triacrylate or trimethylolpropane triacrylate ... 

Although the gel content indicated the presence of substantial cross-linking, the pressure-sensitive adhesive properties could be improved further by incorporating a small amount (1 percent) of pentaerythritol triacrylate (PETA). This system developed a peel value of 5.6 pli with adhesive failure and 22 hours of shear with only 6 seconds of cure time in air (Table 7).
