3M 7000001569 Membrane Switch Spacer 7957MP 24x36 in

Product Description

The 3M 7000001569 is a high-performance acrylic adhesive tape designed for membrane switch spacer applications in general industrial assembly. Sold under the 3M product designation 7957MP, this tape features a 15.4 mil total construction: a 3 mil clear polyester film (PET) carrier bonded with 3M High Performance Acrylic Adhesive 200MP, backed by a 4.2 mil tan 58 polycoated kraft paper liner. It delivers strong shear strength to resist slippage and edge lifting while offering short-term heat resistance up to 400 degrees F and excellent solvent resistance. Installers benefit from initial repositionability, which allows for placement accuracy when bonding to plastic substrates.

This tape is suited for graphic attachment, membrane switch fabrication, and general industrial joining applications. The clear PET carrier maintains a low profile in finished assemblies. Each sheet measures 24 inches by 36 inches, making it practical for bench-cut applications in both OEM manufacturing environments and service shops. Professionals working in electronics assembly, industrial fabrication, and panel manufacturing are the primary installers. The acrylic adhesive system performs reliably after repeated exposure to humidity and thermal cycling, making it appropriate for assemblies that see variable environmental conditions.

Key Features

• 15.4 mil total tape construction with 3 mil clear PET carrier
• 3M High Performance Acrylic Adhesive 200MP for strong, durable bonding
• Initial repositionability supports accurate placement on plastic surfaces
• Short-term heat resistance up to 400 degrees F
• Excellent solvent and shear resistance to prevent edge lifting and slippage
• 4.2 mil tan 58 polycoated kraft paper liner for clean, consistent release

Compatibility

Designed for membrane switch spacer fabrication and graphic attachment in general industrial joining applications where bonding to plastic substrates is required.

Installation Notes

This tape is typically applied by assembly technicians in industrial or electronics manufacturing environments. Ensure bonding surfaces are clean, dry, and free of oils or contaminants before application. Use a firm roller or squeegee to ensure full contact between adhesive and substrate. Initial repositionability allows for minor adjustments, but final positioning should be confirmed before applying pressure to activate full bond strength.
