1) 3M 9500 PC – double stick tape for metal to plastic adhesion
2) 3M 9495LE – heavy duty tape for sticking to powder-coated surfaces, slick plastics
3) “Hook & Loop” (Velcro) on plate and mount- allows for re-positioning, but leaves air space between plate and mount
I use 9500 PC for attaching plates to my acrylic hand buffing block. I use hook & loop for mounting my tintypes to stretchers for exhibition.
Thank you so much for your suggestions!
I tried 3M 9500 before but after 3 years some dags came off from glass/plexiglas mount.
I think the backing of adhesive is too solid (it’s polyester Film) and should be more elastic.
(*But I suppose it works great on tintypes, because they are much lighter than silver-plates)
I also tried Velcro too & that worked perfect!
It’s only one demerit is it’s thickness..

p.s. 1-2 plates shown in the attached image nearly fell off during the recent show. That made a stuff in the museum freak out…
