3M 7000115629 | 36.000" OAL x 24.000" Width x 7.0 mil Thickness Membrane Switch Spacers

3M membrane switch spacer Single Coated 7997MP features 3M high performance acrylic adhesive 200MP, formulated for excellent shear strength, on a 5 mil carrier. This white 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, 3M membrane switch spacer single coated 7997MP is ideal for the stresses of switch actuation over long periods. This single-coated, single-liner membrane switch spacer features a clear 5 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, increases dimensional stability and holds up even under high humidity for efficient storage and processing. The liner design also enables improved rotary die-cutting at high speeds, as well as improved sheet processing.

• 3M Membrane switch spacer single coated 7997MP is constructed with 2 mil high performance acrylic adhesive that is coated on one side of a 5 mil clear polyester film carrier. This membrane switch spacer comes with a 94# moisture-resistant PCK paper liner. Designed to separate switch circuitry until actuation, membrane switch spacer single coated 7997MP provides excellent high temperature resistance (up to 400°F/204°C short-term heat resistance) as well as chemical and UV resistance.

• 3M High performance acrylic adhesive 200MP is an industry standard for graphic attachment and general industrial joining applications. It features outstanding adhesion to metal, polycarbonate (PC), ABS and polyester (PET), making it popular across many industries. This adhesive provides some initial repositionability for placement accuracy when bonding to plastics. It also performs well after exposure to humidity and hot/cold cycles, providing confidence that the switch will perform through difficult environmental conditions and millions of actuations.

• With low cost, long life, outstanding environmental performance and eye-catching graphics, membrane switches are found in more and more applications. They range from farm tractors and medical test systems to microwave ovens and fish finders.
