3M™ 7993MP Membrane Switch Spacer (Single-Coated, Clear) - 24 in. x 36 in.

3M™ Membrane Switch Spacer Single Coated 7993MP features 3M™ High Performance Acrylic Adhesive 200MP, formulated for excellent shear strength, on a 1 mil carrier. This clear PET film provides a smooth, bright appearance, eliminating the need for floodcoat on overlays and keypads. The adhesive withstands repeated switch actuation and forms neat, clean edges for precise slitting and die-cutting.

Featuring 3M™ High Performance Acrylic Adhesive 200MP, our 3M™ Membrane Switch Spacer Single Coated 7993MP is ideal for the stresses of switch actuation over long periods. This single-coated, single-liner membrane switch spacer features a clear 1 mil polyester film carrier which adds brightness and structural strength to exterior surfaces, great for graphic overlays and keypads where floodcoating may otherwise be required. The adhesive is formulated for excellent shear strength – forming a durable bond with plastics and other smooth surfaces with less oozing at the edges. This allows for easier slitting and die-cutting, faster part processing and minimal waste.

The 94# polycoated kraft (PCK) paper liner is heavier than standard liners for improved handling and lay-flat properties. It is designed to cover adhesive consistently for full bonding performance after application. The durable liner resists curling, tunneling and buckling, increase dimensional stability and holds up even under high humidity for efficient storage and processing. Liner design also enables improved rotary die-cutting at high speeds, as well as improved sheet processing.
