COLPHENE® 180 FR GR (fire retardant, granulated) is an SBS-modified bitumen cap ply for use in approved multi-ply waterproofing assemblies. COLPHENE 180 FR GR is composed of a proprietary formulation of elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen and is reinforced with tough, dimensionally stable non-woven polyester mat. The topside is surfaced with ceramic coated granules and the underside is surfaced with fine mineral aggregate to facilitate cold adhesive and hot asphalt applications.
Prior to installation, unroll COLPHENE 180 FR GR onto the surface and allow to relax. Place COLPHENE 180 FR GR in desired position and back roll the product. Apply approved cold adhesive or hot asphalt following manufacturer specifications. COLPHENE 180 FR GR is then rolled into the cold adhesive or hot asphalt and subsequently rolled with a weighted roller. Refer to SOPREMA® specifications and installation instructions for additional application guidelines.
