Scotch® Rubber Mastic Tape 2228 is a conformable self–fusing rubber electrical insulating and sealing tape that consists of an ethylene propylene rubber (EPR) backing coated with an aggressive, temperature–stable mastic adhesive. This tape is made 65 mils (1,65 mm) thick for quick application build–up. It is designed for electrical insulating and moisture sealing applications. It is a UL recognized component for applications up to 130C. It offers excellent resistance to moisture and ultraviolet exposure and is intended for both indoor and weather exposed outdoor applications. Scotch® Rubber Mastic Tape 2228 should be applied in half–lapped layers until desired insulation build up is reached. Stretch the tape to 3/4 of its original width during application for good conformability and to obtain a moisture tight seal. Scotch® Rubber Mastic Tape 2228 should be overwrapped for mechanical protection with two half–lapped layers of Scotch® Super 33+TM Vinyl Electrical Tape.
