3M™ Scotch® 665 Removable Repositionable Tape
3M™ Removable Repositionable Tape 665 is a linerless double coated tape designed for applications requiring light duty bonding. It features differential acrylic adhesives applied to a clear, 1.4 mil UPVC film carrier that resists chemicals and temperatures. This material also provides outstanding adhesive anchorage, and allows for specialized processing such as hot wire cutting.
Unlike many differential removable/repositionable tapes, 3M™ Removable Repositionable Tape 665 features a permanent medium tack 3M™ Acrylic Adhesive 400 on the face side and 3M™ Repositionable Acrylic Adhesive 1070 on the liner side. Adhesive 400 has good temperature performance and peel strength and is ideal for bonding together a wide variety of similar and dissimilar materials such as metals, glass, wood, papers, paints, and many plastics. Adhesive 1070 holds well to many surfaces and provides clean removal without adhesive residue or delamination.
The UPVC film carrier improves the handling and strength of the tape and provides dimensional stability. Together with a low density polyethylene liner, this all-plastic tape construction is excellent for die cutting and laminating, as well as the ability to hot wire cutting.
3M™ Removable Repositionable Tape 665 has no liner, which makes it simple and efficient for manual and automatic dispensing. The UPVC film carrier provides a solid anchor for the adhesives, allowing for clean, efficient one-piece tape removal from many surfaces.
The film carrier also adds dimensional stability and improves tape handling for efficient die cutting and laminating. Its complete plastic construction makes it suitable for specialized processes such as hot wire cutting for foam and plastic packaging applications.
