3M 7000001575 Membrane Switch Spacer Tape 7945MP Clear

Product Description

The 3M 7000001575 is a membrane switch spacer tape designed for precise, high-performance bonding in graphic attachment and general industrial joining applications. This product carries the 7945MP construction, built around a 1 mil clear polyester film (PET) carrier bonded with 3M High Performance Acrylic Adhesive 200MP, and backed by a 4.2 mil tan 58 polycoated kraft paper liner. Total thickness is 13.4 mil. The acrylic adhesive system provides initial repositionability, making placement accuracy achievable before final bond. Licensed electricians, electronics technicians, and industrial assembly professionals install this tape in applications requiring long-term bond integrity under thermal and environmental stress.

This tape is suited for membrane switch panel assembly, graphic overlays, and industrial joining where exposure to humidity, heat cycling, and solvents is a concern. Each sheet measures 24 inches x 36 inches, offering a workable format for both precision die-cut applications and hand-cutting in the field. The clear PET carrier maintains dimensional stability, supporting clean and consistent adhesive transfer to plastics and other substrates common in industrial control panel fabrication.

Key Features

• 13.4 mil total construction: 1 mil clear PET carrier, acrylic adhesive 200MP, 4.2 mil PCK liner
• Initial repositionability for placement accuracy when bonding to plastics
• Short-term heat resistance up to 400 degrees F
• Excellent solvent resistance for demanding industrial environments
• High shear strength resists slippage and edge lifting over time
• Performs reliably after repeated humidity and hot/cold thermal cycles

Compatibility

Designed as an industry-standard adhesive tape solution for membrane switch spacer assemblies, graphic attachment, and general industrial joining applications where acrylic adhesive bonding to plastics and rigid substrates is required.

Installation Notes

This tape is typically applied by electronics assembly technicians or industrial maintenance professionals working on control panel overlays and membrane switch stacks. Clean all bonding surfaces thoroughly before application to remove oils, dust, and residue that may compromise adhesion. Take advantage of the initial repositionability window to confirm alignment before applying full pressure. Once final position is confirmed, apply firm, even pressure across the entire bond area to achieve full adhesive contact.
