Title:
SILICONE COMPOSITE STAIN-RESISTANT SHEET AND CONSTRUCTION METHOD USING SAME TO PREVENT GRAFITTI
Document Type and Number:
WIPO Patent Application WO/2021/215081
Kind Code:
A1
Abstract:
The present invention is a silicone composite stain-resistant sheet characterized by comprising a base material layer, and layered on one surface of the base material layer, a silicone adhesive layer having a hardness of 5 or less as measured by an Asker C durometer and an adhesive force of 5 N/25 mm or more with respect to a mortar test piece, wherein, of the surfaces of the base material layer, the surface facing away from the surface whereon the silicone adhesive layer has been layered has undergone stain resistance treatment with a silicone hard coat agent containing a fluorine-containing silicone compound. In this manner, a silicone composite stain-resistant sheet and a construction method using same to prevent graffiti can be provided, the silicone composite stain resistant sheet, which demonstrates stain-resistance and washability stably over the long term, is adhered readily onto an adherend and can conform to cracks and misalignments on a work surface.
