3M™ ElectroCut™ Film Series 1170 is a durable, transparent, acrylic colored film coated with a transparent, pressure-sensitive adhesive that is protected by a removable liner. It is intended for use on 3M Reflective Sheeting as part of 3M’s Matched Component System™ for signing. Colored E.C. Film is often used instead of silk screened inks to provide transparent colored background copy for retroreflective street name signs and other traffic control signs.
The 3M ElectroCut™ Film Series 1170 is a durable, transparent acrylic film with a pressure‑sensitive adhesive, offered in several colors for use on 3M reflective sheeting. It is designed for kiss‑cutting on electronic cutting machines and can be supplied pre‑punched or unpunched depending on the cutter type.
The bulletin provides detailed color codes, retroreflection coefficients, storage conditions, recommended cutting practices, and recommended transfer tapes for optimal application on traffic‑control signs and other permanent signage.
