    摘要: This invention relates to a process for applying a coating material comprising a release coating composition or a pressure sensitive adhesive composition to a substrate, the process comprising: (A) atomizing and electrically charging said coating material; and (B) spraying the atomized and charged coating material from step (A) on to a substrate which overlies a grounded support structure. In one embodiment, the coating material sprayed during step (B) is a release coating composition, said process further comprising the additional steps of: (C) curing said release coating composition; (D) atomizing and electrically charging a pressure sensitive adhesive composition; (E) spraying the pressure sensitive adhesive composition from step (D) on to said substrate over the cured release coating composition from step (C); and (F) placing another substrate over the sprayed pressure sensitive adhesive composition from step (E).
