Abstract:
This invention relates to a process for applying a coating material comprising a release coating composition (204) or a pressure sensitive adhesive composition (206) to a substrate (202), the process comprising: (A) atomizing and electrically charging said coating material; and (B) spraying (102, 104) the atomized and charged coating material from step (A) onto a substrate (202) which overlies a grounded support structure (108). In one embodiment, the coating material sprayed during step (B) is a release coating composition (204), said process further comprising the additional steps of: (C) curing said release coating composition (204); (D) atomizing and electrically charging a pressure sensitive adhesive composition (206); (E) spraying the pressure sensitive adhesive composition (206) from step (D) onto said substrate (202) over the cured release coating composition (204) from step (C); and (F) placing another substrate (208) over the sprayed pressure sensitive adhesive composition (206) from step (E).
