    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).

    Abstract translation: 本发明涉及一种将包含脱模涂料组合物(204)或压敏粘合剂组合物(206)的涂料施用于基材(202)的方法,该方法包括:(A)雾化并对所述涂料进行充电; 和(B)将来自步骤(A)的雾化和带电的涂层材料喷涂(102,104)到覆盖在接地支撑结构(108)上的衬底(202)上。 在一个实施方案中,在步骤(B)期间喷涂的涂料是一种脱模涂料组合物(204),所述方法还包括以下附加步骤:(C)固化所述脱模涂料组合物(204); (D)对压敏粘合剂组合物(206)进行雾化和充电; (E)从步骤(D)将来自步骤(D)的压敏粘合剂组合物(206)喷射到来自步骤(C)的固化的脱模涂料组合物(204)上的所述基材(202)上; 和(F)将来自步骤(E)的喷涂的压敏粘合剂组合物(206)上的另一个基底(208)放置在其上。
