3M™ Extreme Sealing Tapes
Single-sided 3M Extreme Sealing Tape is a category of highly flexible yet durable, scuff resistant tapes for the most challenging sealing applications. While the high tack acrylic adhesive provides excellent adhesion to most surfaces, its quick stick creates an immediate seal without the oozing or staining seen in adhesives and mastic tapes. The proprietary ionomer copolymer backing conforms around bends, ridges, and bolt / rivet heads. This combination provides a quick to apply, long-term sealing solution that can withstand outdoor extremes for multiple years.
Applications include: Roof sealing on trucks, heavy equipment, and trailers. Skylight, vent, and window sealing. HVAC drip pan sealing
