3M Scotch 924 ATG Tape is a permanent unsupported acrylic adhesive transfer film (pressure-sensitive adhesive pre-applied to a special release liner). 3M 924 is a permanent, all-purpose transfer tape that offers excellent adhesion to most paper stocks. Can bond a wide variety of similar and dissimilar materials such as metals, glass, wood, papers, paints, and many plastics. Some application ideas include mounting promotional items and posters, core starting, and mounting picture frame mat boards and dust covers. Has good solvent resistance and excellent UV resistance. The main difference between 3M 908 and 3M 924 ATG tapes is that 908 is pH neutral (acid-neutral). Scotch 924, like all ATG tapes, is reverse wound on the roll so it is designed to be used in an ATG dispenser/gun. Please see matrix below to confirm which ATG refill rolls work in which ATG dispensers (you can also watch a YouTube video demonstrating the compatibility between ATG refill rolls and ATG guns).
