Abstract:
1. A method for manufacturing a siliconized release paper, the method comprising: making a base paper; running the base paper in line to a dryer; drying the base paper in a manner which is effective for glazing at least one surface of the base paper to provide a glazed base paper; running the glazed base paper in line to a precoater; precoating the glazed surface of the glazed base paper to provide a precoated glazed base paper; running the precoated, glazed paper in line to calendering rolls; calendering the precoated glazed based paper to provide a calendered, precoated and glazed base paper; running the calendered, precoated and glazed base paper in line to a siliconizer, siliconizing the calendered precoated and glazed surface of the calendered, precoated glazed base paper by applying a release coating composition which includes a silicone composition to provide a siliconized base paper, and curing the release composition to provide a siliconized calendered release paper.
