Product Name: 3M™ Membrane Switch Spacer 7966WDL, 24 in x 36 in, 9 mil, (50 sheets) Case
Product Description: 3M™ Membrane Switch Spacer 7966WDL features a 2 mil white PET film carrier with a metallized vapor coat for added opacity, ideal for graphics. 3M™ High Performance Acrylic Adhesive 200MP delivers excellent shear strength during repeated switch actuation and forms clean edges for precise slitting and die-cutting. A PCK paper liner resists humidity and adds stability for improved sheet processing.
A Top Performer Before, During and After Application
Featuring 3M™ High Performance Acrylic Adhesive 200MP, our 3M™ Membrane Switch Spacer 7966WDL is excellent for graphic applications. Its white 2.0 mil polyester film carrier adds structural strength, and a metallized vapor coating creates outstanding opacity for vivid graphic displays. The adhesive, applied at 2.0 mils on the face side and 5.0 mil on the back side, is ideal for the stresses of switch actuation over long periods. It 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.
Twin 4.2 mil 58 lb. polycoated kraft (PCK) paper lay-flat liners are designed to cover adhesive consistently for full bonding performance after application. Liners resist curling, tunneling and buckling, increases 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.
Recommended Applications
- Membrane switch spacers
- Graphic and non-graphic applications
- Switch mounting
- Circuit layer assembly
- Metal dome placement
- Lead protection
- Die-cut laminations
Resilient and Ready
3M™ Membrane Switch Spacer 7966WDL is constructed with 2 mil adhesive on the face side and a 5 mil adhesive on the back side of a 2.0 mil white metallized vapor-coated polyester film carrier. This membrane switch spacer is double-linered with twin 4.2 mil, 58 lb. moisture-resistant, lay-flat, PCK paper liners. Designed to separate switch circuitry until actuation, our 3M™ Membrane Switch Spacer 7966WDL provides excellent temperature resistance (up to 400?F/204?C short-term heat resistance), solvents and UV resistance.
About Our High Performance Acrylic Adhesive 200MP
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.
The Right Choice for a Range of Applications
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. Whatever the need, 3M has a membrane switch construction suited for the job.
