スベスト施工層用の塗布剤に関する。Detailed Description of the Invention [Object of the Invention] (Industrial Application Field) The present invention is directed to the surface of an asbestos layer sprayed onto the surface of a structure such as a building for the purpose of heat insulation, or
By applying it to the construction surface after the old asbestos layer has been peeled off and removed, it prevents any asbestos that still remains attached to the surface of the asbestos construction layer or the peeled and removed surface of the asbestos layer from coming off later. Regarding coating agents for asbestos construction layers, which are useful for such purposes.
（従来の技術）
昨今、アスベストに対しては、発ガン原因物質の一つと
しての認識が高まりつつある。(Prior Art) In recent years, asbestos has been increasingly recognized as one of the cancer-causing substances.
そこで、学校の校舎などに施されていた古いアスベスト
施工層を剥離除去する工事が各所で行なわれている。Therefore, work is being carried out in various places to peel off and remove old asbestos construction layers that were applied to school buildings and other buildings.
ところが、この剥離工事の際には、アスベストが粉塵状
