COLPHENE Sanded is an SBS-modified bitumen cap ply for use in approved multi-ply membrane waterproofing assemblies. COLPHENE Sanded is composed of a proprietary formulation of elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen and is reinforced with a high-quality random glass fiber mat. The topside and underside are surfaced with fine mineral aggregate to facilitate cold adhesive and hot asphalt applications.
