Self adhesive bitumen cover tape is one type of modified bitumen waterproofing tape which use synthetic rubber such as SBS, SBR, SIS, good quality asphalt and base materials(or without base mat). The surface is covered by aluminum foil, PE film or colored aluminum foil(Blue, Grey, Red, Black etc.) and the silicon depositing release film is covered on the lower surface as anti-sticking layer.
