3M™ Grid Air Sealing Tape 8068 is an air, vapor, moisture and water impermeable tape with an aggressive, high-tack pressure sensitive acrylic adhesive. This tape is available in both self-wound and linered versions. It can be used in a variety of building construction applications.

Reinforced Scrim Helps Strengthen Backing and Reduce Stretch of Tape
3M™ Grid Air Sealing Tape 8068 is a 10 mil tape with a high-tack acrylic adhesive and a reinforcing scrim. This tape is designed for preventing air, vapor and moisture intrusion in building construction applications. The scrim helps reduce stretching and strengthens the backing. The film backing seals around staples, nails and other penetrations to help prevent intrusion by moisture, air or vapor. With up to 12 months of UV resistance, this tape permits an extended application temperature range between 0°F to 176°F (-18°C to 80°C) and a service temperature range from -40°F to 240°F (-40°C to 116°C).
Recommended Applications

Seaming air and vapor membranes
Taping gaps and penetrations to stop free air flow
Sealing around openings and joints in building applications
Sealing of penetrations and window joints in exterior walls
Sealing of holes and feed locations for cabling

Dependable Adhesion with Acrylic
3M™ Grid Air Sealing Tape 8068 features a high-tack, aggressive, pressure sensitive acrylic adhesive that bonds to a wide selection of building construction materials. This includes concrete, concrete block, plaster, fiberglass, anodized aluminum, galvanized metal, exterior gypsum and plywood, all without the use of any adhesion promoters. The acrylic adhesive maintains adhesion in climate and temperature change variations.
