3M 9415PC is a translucent polyester film differentially coated with a removable/repositionable, low tack, adhesive on one side (back/liner side) and a permanent, high tack, adhesive on the other (face/exposed side). Unlike the other differentially coated tapes on the web site the removable side on this tape is also repositionable so its good when you need multiple openings and closings. Also its removable low tack side offers only nominal adhesion so its good for paper mailings since it will not cause delamination from most paper stock.
Scapa S301 is a clear UPVC film tape coated on both sides with an exceptionally high tack, high peel, acrylic adhesive system. It offers excellent adhesion even to demanding surfaces such as sports jerseys. It also meets the compositional requirements of FDA regulation 21 CFR175.105 (adhesives) for indirect food contact.
3M 4952 VHB tape is a closed-cell firm acrylic foam which is coated on both sides with a low-surface energy synthetic adhesive. This is the tape in the 3M VHB family best suited to bond to many lower surface energy substrates including many plastics and powder coated paints. The tape offers excellent adhesion, durability and solvent and moisture resistance.
