Summary: | To provide a silicone composite anti-fouling sheet expressing anti-fouling property, washability, easy washability, and abrasion resistance stably for a long period of time, and capable of easily attaching to an adherend, capable of following cracks and shears of a face to be constructed, and a scribble-proof construction method using the same.SOLUTION: A silicone anti-fouling sheet 4 includes a substrate layer 1, and a silicone adhesive layer 2 laminated on one side of the substrate layer, where the substrate layer is composed of a fluorocarbon resin, the silicone adhesive layer has a hardness of 5 or less measured by an Asker C hardness meter, the tack strength to a mortar test piece is 5 N/25 mm or more, and a surface opposite to a face laminated with the silicone adhesive layer out of surfaces of the substrate layer is an anti-fouling face 7.SELECTED DRAWING: Figure 1
【課題】長期に安定して防汚性、洗浄性、洗浄容易性、耐摩耗性を示し、また、被着体に容易に貼りつけることができ、被施工面の割れやずれに対しても追従可能であるシリコーン複合防汚シート、及びそれを用いた落書き防止施工方法を提供する。【解決手段】基材層1と前記基材層の片面に積層したシリコーン粘着層2とを含むシリコーン複合防汚シート4であって、前記基材層がフッ素樹脂で構成され、前記シリコーン粘着層が、硬さがアスカーC硬度計で5以下であり、かつ、モルタルテストピースに対する粘着力が5N/25mm以上のものであり、前記基材層の表面のうち、前記シリコーン粘着層を積層した側の面の反対側の表面が防汚面7であることを特徴とするシリコーン複合防汚シート。【選択図】図1 |
