COLPHENE® 180 PS (polyolefin, sanded) is an SBS-modified bitumen base ply for use in approved multi-ply membrane waterproofing assemblies. COLPHENE 180 PS is composed of a proprietary formulation of elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen and is reinforced with a tough, dimensionally stable non-woven polyester mat. The topside is surfaced with polyolefin burn-off film and the underside is surfaced with fine mineral aggregate to optimize cold adhesive or hot asphalt application.
Prior to installation, unroll COLPHENE 180 PS onto the surface and allow to relax. Place COLPHENE 180 PS in desired position and back roll the product. Apply approved cold adhesive or hot asphalt following manufacturer specifications. COLPHENE 180 PS is rolled into the cold adhesive or hot asphalt and subsequently broomed in if utilizing hot asphalt or rolled with a weighted roller if utilizing cold adhesives. Subsequent approved inter-ply or cap ply membranes are applied to COLPHENE 180 PS via heat welding. Refer to the SOPREMA® specifications and installation instructions for additional application guidelines.
