Product Details
3M™ Industrial Sealing Tape IS1 provides an easy sealing method that creates a moisture barrier under panels or where rivets, screws, or nails are present in automotive, specialty vehicle, electronic, heating, ventilation, and cooling (HVAC), and wind energy applications. This conformable tape is engineered with a waterproof membrane and acrylic adhesive that helps protect interior environments from leakage at joints, including panels, floors, trim, and frames, by sealing around the fastener for a secure seal. The tape offers aggressive adhesive forming a strong bond on various surface types such as anodized aluminum, galvanized metal, fiberglass, plywood, and more. It is highly conformable with a thin, flexible backing designed to fit in between panels and tight spaces, and user-friendly, featuring a liner that promotes precise product placement for ease of application. The tape can be applied in temperatures as low as 0 °F (-18 °C) and operates within a temperature range of -40 °F to 240 °F (-40 °C to 116 °C). This product provides a reliable and effective alternative to slow-curing and messy liquid sealants, offering robust adhesion that sticks to most substrates, excelling in water leak prevention around RV windows, automotive frames, HVAC system interior joints, electrical enclosures, and other industrial uses.
