Double-sided silicone coated liner

摘要

A double-sided silicone-coated liner, particularly adapted for use in self-wound tapes is described which is a paper upon which a silicone coating layer is deposited on one surface and a water vapor permeable silicone coating layer is applied on the liner's opposed second surface. The liner surfaces may optionally be clay coated, the clay coating adjacent to the water vapor permeable silicone coating layer also having water vapor permeability.PPThe tape made using this particular liner typically additionally has a carrier layer with an adhesive sandwiched between the silicone coating layer and the carrier. The tape is prepared by the steps of coating the liner with a silicone layer on a first side of the liner; drying the silicone layer; coating an adhesive onto an exposed surface of the silicone layer; laminating a carrier layer onto the adhesive; coating a second side of the liner, opposed from the first side with a water vapor permeable silicone layer; drying the water vapor permeable silicone layer; and remoisturizing the liner.
