3M 7000021297 Repositionable Tape 665 Clear 1in X 72yd

Product Description

The 3M 7000021297 is a linerless, double-coated repositionable tape built on a clear UPVC film carrier. One side uses 3M Acrylic Adhesive 400 for strong, durable bonding to metals, glass, wood, paper, paints, and most plastics. The other side uses 3M Repositionable Acrylic Adhesive 1070, which holds firmly but allows clean removal without leaving residue. The tape measures 1 inch wide by 72 yards long and is 3.8 mil thick. It carries slight differential tack between the two adhesive sides, giving installers flexibility for temporary or semi-permanent mounting applications.

This tape is suited for commercial and industrial applications where a part must be positioned accurately before final bonding, or where clean removal is a priority. Adhesive 400 performs well in low-temperature environments and delivers reliable peel strength across a wide range of substrates. The clear UPVC film carrier provides UV resistance and optical clarity, making it appropriate for window label and display applications. Adhesive 1070 is designed for medium HSE and medium LSE surfaces and offers good resistance to moderate solvents and low-temperature conditions.

Key Features

• Linerless double-coated construction with two distinct acrylic adhesives on a single tape
• Adhesive 400 bonds metals, glass, wood, paper, paints, and most plastics with strong peel strength
• Adhesive 1070 allows clean repositioning and removal from many surfaces
• Short-term heat resistance up to 250 degrees F on the Adhesive 400 side
• Clear UPVC film carrier offers UV resistance for window and display label use
• Medium solvent resistance and low-temperature performance on both adhesive sides

Compatibility

Designed for bonding similar and dissimilar materials including metals, glass, wood, uncoated papers, paints, and many plastics in commercial and industrial mounting and labeling applications.

Installation Notes

Surface preparation is critical — clean and dry all substrates before application to ensure full adhesive contact. Apply firm, even pressure across the tape length to seat both adhesive layers properly. When using the repositionable side for temporary placement, avoid repeated lifting, as adhesion will diminish over time. Remove the tape in a slow, controlled motion at a low angle to maintain clean removal.
