Zero Permeability Cladding and JacketingThe silver aluminum exterior provides an attractive aesthetic for cladding that is visible when finished. This tape meets UL 723 requirements for flame and smoke spread and is puncture and tear resistant. The self-adhesive material cuts and installs easily on-site and without the use of special tools. The backing is flexible to conform to curved and irregular surfaces with ease. 3M™ VentureClad™ Insulation Jacketing Tape 1577CW is a cladding option for3M™ Interam™ Endothermic Mat E-5A-4 and meets ULI709 Standards - UL Design Number BYBU.XR202. Meets or exceeds most building code requirements. For more information on specific approvals, please refer to the technical data sheet.Adheres in Cold Temperatures3M™ VentureClad™ Insulation Jacketing Tape 1577CW features an aggressive pressure sensitive acrylic adhesive that bonds and seals well in cold temperatures. This adhesive adheres immediately on contact to a variety of materials such as fiberglass, faced fiberglass insulation, mineral wool, polystyrene and flexible aerogel. It applies easily at temperatures as cold as -10F/-23C. It can operate at a service temperature as low as -94F/-70C and as high as 300F/149Once bonded, this tape will provide good holding power for extended periods with good aging properties and resists lifting and curling over time.This product is used to protect insulation against UV, ozone, high humidity, salt spray, weather, oil and grease, aggressive chemicals, impact and mechanical abuse, corrosion under insulation (CUI), and moisture vapor intrusion. It works well with many insulation types. Qualifies for compliance credit for LEED® .Recommended ApplicationsVapor barrier for insulation cladding and jacketing operations such as HVAC ductwork and pipingInterior and exterior ductwork (rectangular/round), pipes (straight runs, bends, intersections), and vesselsWeather protection system in extreme environmental conditionsCladding option for 3M™ Interam™ Endothermic Mat E-5A-4The Science of Better Adhesion from 3MSince 1925 when one of our lab assistants invented masking tape, 3M has been applying science to life - developing adhesive products and technologies that help entire industries and individual businesses worldwide. The work that began with a single 3M engineer now spans decades and generations. And all of it goes into each of our industrial tapes and adhesives, like 3M™ VentureClad™ Insulation Jacketing Tape 1577CW, to help businesses like yours operate faster, better and more efficiently.
