3M Scotchfil Electrical Insulation Putty is a self-amalgamating, rubber-based tape designed to fill voids, seal irregular surfaces, and provide reliable electrical insulation on cables, connectors, and splices. Its pliable, putty-like consistency allows it to conform tightly to irregular shapes for a secure, moisture-resistant seal.
Ideal for MRO, utility, and industrial electrical applications, this 1-1/2 in x 60 in roll delivers consistent performance in demanding environments. It is compatible with standard electrical taping systems and works alongside phase-color and vinyl finishing tapes for complete splice protection.
