COLVENT™ 180 SA SKU: 00376

COLVENT 180 SA is an SBS-modified bitumen base ply for use in approved multi-ply membrane and flashing assemblies. COLVENT 180 SA is composed of a proprietary formulation of elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen in combination with high tack self-adhesive ribbons and is reinforced with a tough, dimensionally stable non-woven polyester mat. The ribbon strips are arranged in a pattern to vent vapor pressure between the substrate and the COLVENT 180 SA. The topside is surfaced with fine mineral aggregate to optimize cold adhesive applications and the underside is surfaced with protective polyolefin release film that is removed during application.
