Hello, Has Legion tested mounting paper with “nano tape”? My understanding is there is no adhesive in nano tape.

Legion has not tested mounting with nano tape. To preserve the longevity of a work of art, we recommend using archival, acid-free adhesive tapes. Mounting paper with non-archival adhesives may lead to degradation or discoloration over time.

Although Nano Tape does not use a traditional chemical adhesive, the gel-like adhesive is not suitable for long term storage and may weaken over time.
