Epoxy groups, electron-beam exposure

Figure 6. Infrared absorbance of epoxy group in phenolic resin matrix, as a function of electron beam exposure dose.

Silicone acrylates (Fig. 5) are again lower molecular weight base polymers that contain multiple functional groups. As in epoxy systems, the ratio of PDMS to functional material governs properties of release, anchorage, transfer, cure speed, etc. Radiation induced radical cure can be initiated with either exposure of photo initiators and sensitizers to UV light [22,46,71 ] or by electron beam irradiation of the sample.
