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).

Process using electrostatic spraying for coating substrates with release

A pressurizing tank for a liquid dispensing system is disclosed. The system includes a pressure withstanding vessel having openings at both ends with a strainer fitting fixed in one of the openings. A flexible, inflatable, gas-tight bag is provided in the vessel and has an inflating valve at one end thereof which is fixed in the other opening in the vessel. The other end of the bag is fixed to the strainer fitting.
