3M 7000001570 Membrane Switch Spacer 7956MP 24x36 in

Product Description

The 3M 7000001570 is a membrane switch spacer tape, designated 7956MP, designed for precision graphic attachment and general industrial joining applications. The tape features 3M High Performance Acrylic Adhesive 200MP applied to a 2 mil clear polyester film (PET) carrier. Total construction thickness is 14.4 mil, consisting of the adhesive layer, PET carrier, and a 4.2 mil tan 58 polycoated kraft paper liner. The adhesive provides initial repositionability for accurate placement on plastics and maintains strong performance after exposure to humidity and repeated hot and cold thermal cycles. This product is installed by industrial assembly technicians and graphic application professionals working in manufacturing and electronics environments.

This tape is suited for membrane switch assembly, graphic overlay bonding, and general industrial lamination where a clear, high-strength acrylic adhesive is required. The 24 inches x 36 inches sheet format is appropriate for flat panel and overlay applications requiring full-sheet coverage. The 2 mil polyester carrier provides dimensional stability during handling and die-cutting operations. Applications span electronics manufacturing, industrial controls, and graphic arts production environments.

Key Features

• 14.4 mil total tape thickness for consistent spacer performance in membrane switch stacks
• 3M High Performance Acrylic Adhesive 200MP with initial repositionability for placement accuracy on plastics
• Short-term heat resistance up to 400 degrees F
• Excellent solvent resistance for demanding industrial environments
• Strong shear strength resists slippage and edge lifting after bonding
• Clear 2 mil PET carrier maintains visual clarity and structural stability

Compatibility

Designed for use in membrane switch spacer assemblies and graphic overlay bonding applications where a high-performance acrylic adhesive on a polyester film carrier is specified.

Installation Notes

Surface preparation is critical before application — clean bonding surfaces of dust, oils, and contaminants prior to lamination. Apply firm, even pressure across the full sheet after positioning to ensure full adhesive contact. Power down any electronic assemblies before integrating this tape into membrane switch stacks. Die-cutting should be performed with sharp tooling to maintain clean edge geometry and prevent adhesive squeeze-out.
