1″ x 8feet 3M® ScotchliteTM 8850 Reflective Film Tape is a thin, flexible, lightweight, retro-reflective film with a rubber-based self-adhesive.
It is outstanding for application to raingear, backpacks, motorcycle jackets, satchels, totes, boots and other outdoor apparel.
3M 8850 has a clear peel-off liner on the adhesive side and a layer of white protective paper covering the outside reflective surface. Once applied, the white paper layer is peeled off (after 72 hours) to reveal the enclosed lens (glass-bead) reflective surface.
It is very bright, having a reflectivity of 500 Candelas/Lux/sq. meter. 3M 8850 will stay in place permanently, though it is not recommended for permanent clothing applications that require wash durability.
3M 8850 can be removed at any time in one continuous piece and can be used on t-shirts, jerseys, and sports jackets for twilight or night time running (note that 8850 appied to T-shirts will survive washing at a warm setting and moderate heat drying, will come out wrinkly, but the reflectivity will not be significantly diminished).
Application Instructions: 3M 8850 has both a clear plastic liner covering the adhesive side and a white paper liner covering its silver reflective side.
Cut a piece to size and remove the clear liner to expose the adhesive (#1 above).
Turn it over and lightly place the tape into position, then press it down firmly onto the fabric over a hard surface. Allow 72 hours for the adhesive to reach maximum strength.
Then, using your fingernail or an Exacto Blade, carefully “pick” up a corner of the paper liner to begin separating it from the reflective layer (#2 above).
While keeping close to its surface, slowly peel away the liner by pulling it toward its opposite end to fully expose the reflective surface.
