3M Acid-Free ATG Tape 1/4" x 36 Yard Roll
This double-sided unsupported acrylic adhesive transfer film tape is a pressure-sensitive adhesive pre-applied to a special release liner. It has an acid free/acid-neutral (pH 7.0 - 8.5) acrylic adhesive and is photo-safe per both Black and White Photographic Activity Tests and Color Photographic Activity Tests (per ANSI IT9.16).
3M 908 is used for general purpose applications for holding most paper, foil, film, metal, glass and sealed wood including matting and framing pictures, artwork and documents, memory and scrapbooks, general crafts, and school projects. The main difference between 3M 908 and 3M 924 ATG tapes is that 908 is pH neutral (acid-neutral). Scotch 908 Gold, like all ATG tapes, is reverse wound on the roll, so it is designed to be used in an ATG gun
