What chemicals are good to strip backcoating off reel tapes.
NO! NO! NO! I don't want to send them out for stripping. Way too expensive. I don't even want to strip the entire tape.
What I need is to clean the backcoat off the oxide layer. The tape was given a "B" wind after developing sticky shed and, in places, some backcoating "hairs" got stuck between adjacent layers and adhered to the binder. This was exacerbated further by baking. The stuff just turned to goo and spread out on the surface of the binder like butter on bread in the oven.
Alcohol works but also dissolves the binder an many instances. No way of knowing the tape stock since the boxes are generic, reels are haphazard but the backcoating is of the thick, matte gooeyer variety.
Any help appreciated! :-)
