Abstract (in Japanese) (See Japanese page) 
(in English) The authors have already reported that when relays were operated to break load currents in vapors evaporated from a newly-developed acryl-based non-silicone-type polymer that can be used as replacement of conventional silicone-type products, the resultant contact resistance characteristics show no deterioration. In this paper, for the purpose of investigating influences of differences in curing processes, the acryl-based non-silicone-type polymers of UV-radiation-cured type were used, and influences of its vapors on contact resistance characteristics of relays at an ambient temperature of 120ºC were studied. Specifically, a commercially-available mechanical relay (AgSnIn contacts) was sealed into a metal can with one of these acryl-based polymers, and placed in a heating chamber to operate 40,000 break operations of an inductive DC 14V-1A or 14V-0.4A load current at an operating frequency of 1 Hz or 0.5 Hz. As a result, the relays showed no deterioration in contact resistances. Thus, it has been confirmed that vapors from these UV-cure-type acryl-based polymers cause no adverse affects on contact resistance characteristics of relay contacts to be operated in the vicinity.
