3M tapes for retro-fitting of display cases


Clear tape 3M Type 850

Archival quality tape, tested for use inside museum display cases

To improve air-tightness of museum showcases. Gaps between glass panes can be covered nearly invisibly. Minimizing air exchange by improved seals reduces infiltration of pollutans and allows longer service intervals for passive humidity buffering. 3M type 850 doesn't outgass substances which might be harmful to museum objects*.
