Seal, Seam and Splice Sheathing and Housewrap
3M™ Construction Seaming Tape 8087CW is a versatile sheathing tape designed for seaming, splicing, sealing and repairing materials used for moisture barriers, both inside and out. This includes sheathing, weather resistant barriers and moisture barriers. Taping seams aids in reducing air infiltration, improves the effectiveness of insulation and reduces heating and cooling costs. This tape is formed from a rugged biaxially oriented polypropylene film backing which is coated with an aggressive industrial grade pressure sensitive acrylic adhesive. The backing is conformable to irregular surfaces and contours to help ensure a tight seal. It remains flexible when cold, can be applied from 10°F/-23°C to 185°F/85°C and has a service temperature range from -40°F/-40°C to 185°F/85°C. This tape features a low moisture vapor transmission rate and does not compromise the performance of vapor barriers. It unwinds easily by hand or with a 3M hand-held applicator.

Recommended Applications

• Closure system and seam sealer on housewrap and exterior sheathing materials
• Seaming polyethylene vapor barriers
• Repair holes and tears in exterior building wraps
• Seaming extruded foam products

Cold Temperature Performance
3M™ Construction Seaming Tape 8087CW features an aggressive pressure sensitive acrylic adhesive that performs well in cold temperatures. This adhesive adheres immediately on contact to a variety of materials such as housewrap, insulated sheathing, vapor barrier film and unfinished wood. It can be applied down to 10°F/-23°C and performs at temperatures as low as -40°F/-40°C. Once bonded, this tape provides good holding power for extended periods with good aging and UV resistance. It resists lifting and curling.
