The polyurethane protective tape 8561 (indoor grade) by 3M™ is made from an abrasion-resistant polyurethane elastomer that resists puncture, tearing, abrasion, and erosion. 3M 8561 tape provides a simple, easy, and fast method of protecting a surface from corrosion, abrasion, erosion, and minor impact damage. The protective tape is constructed with a pressure-sensitive, acrylic adhesive protected with an easy-release polyester liner. 3M 8561 tape is a transparent tape available with a polyester liner only. 8561 tape has been used to isolate and protect substrates from environmental damage and corrosive elements.
