ELASTOPHENE® Stick is an SBS-modified bitumen, self-adhered base ply for use in approved multi-ply membrane and flashing assemblies. ELASTOPHENE Stick is composed of a proprietary formulation of elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen in combination with a high tack self-adhesive layer and is reinforced with a high quality random glass fiber mat. The topside is surfaced with fine mineral aggregate to facilitate self-adhered, cold adhesive and hot asphalt applications and the underside is surfaced with protective polyolefin release film that is removed during application.
Prior to installation, unroll ELASTOPHENE Stick onto the roof surface and allow to relax. Place ELASTOPHENE Stick in desired position. Remove the protective release film from the underside of the sheet and roll ELASTOPHENE Stick into place with a weighted roller. Subsequent approved inter-ply or cap ply membranes are applied to ELASTOPHENE Stick via self-adhered, cold adhesive and hot asphalt applications. Refer to the SOPREMA SBS Roofing Manual for additional application guidelines.
