Premier XtraBond 1500NS is a durable, single component, non-skinning butyl- based solvent release sealant. XtraBond 1500NS is designed to deliver excellent adhesion to panels and roofing materials while remaining permanently pliable. XtraBond 1500NS is non-staining and is considered to be the ideal choice in applications where the combination of moisture and cold temperatures would cause the break-down of other sealants. It is also an excellent solution when exposed to high or low temperature extremes. For application purposes, the substrate must be clean, dry, frost free, sound and free of any oils, greases or incompatible sealers, paints or coatings that may interfere with adhesion. Do not apply if surface is damp or contaminated. It is recommended to test all substrates prior to applications. For best results, prepare for a clean surface, cut nozzle to desired bead size, apply with caulking gun forcing the sealant onto the substrate, then tool, if needed. Clean excess XtraBond 1500NS sealant with mineral spirits or similar solvent.
