3M Scotch Fine Line Tape 265 is a high-performance film-backed tape designed for in-mold fine line masking where sharp, clean, gel-coat color separation lines are desired. Scotch Fine Line Tape 265 unwinds easily and its strong backing minimizes stretch during roll unwind. Scotch Fine Line Tape 265's polypropylene backing has superior gel coat chemical resistance compared to vinyl backings. Scotch Fine Line Tape 265's silicone-rubber adhesive provides excellent adhesion to semi-permanent, high-slip mold releases compared to conventional rubber-resin adhesives. Silicone -rubber adhesive pulls smoothly from high slip mold releases and 265 tape's polypropylene backing is conformable yet strong enough to pull sharply, evenly and consistently through gel coatings. This Silicone-rubber adhesive can be applied to surfaces at lower temperatures compared to conventional rubber-resin adhesives.
