3M 8777 Sealing Tape
Categories:	Polymer; Tape
Material Notes:	3M™ Sealing Tape 8887 is a self-adhered, waterproof membrane designed for sealing on difficult to stick to surfaces. This product has a unique acrylic pressure sensitive adhesive that aggressively sticks and stays stuck both at lower and higher application temperatures. The proprietary backing seals around hand driven nails and staples to prevent moisture intrusion. This backing is tough, resist punctures and tears, yet it is thin and conformable to fit conveniently into corners. Information provided by 3M
