3M™ Membrane Switch Spacer Single Coated 7993MP is a high-performance spacer designed for demanding switch applications. It features the 3M™ High Performance Acrylic Adhesive 200MP, known for its exceptional shear strength and durability. This single-coated spacer includes a clear 1 mil PET film carrier that provides a smooth, bright appearance, eliminating the need for floodcoat on overlays and keypads.
- High Performance Adhesive: The 3M™ High Performance Acrylic Adhesive 200MP offers outstanding shear strength, forming durable bonds with plastics and other smooth surfaces. This minimizes adhesive oozing at the edges, facilitating precise slitting and die-cutting.
- Clear PET Film Carrier: The 1 mil polyester film carrier enhances brightness and adds structural strength, making it ideal for graphic overlays and keypads where floodcoating might otherwise be required.
- Heavy PCK Paper Liner: The 94 lb. polycoated kraft (PCK) paper liner offers superior handling and lay-flat properties, ensuring consistent adhesive coverage. This durable liner resists humidity, curling, tunneling, and buckling, enhancing dimensional stability for efficient storage and processing.
- Enhanced Processing: The liner design allows for improved rotary die-cutting at high speeds and enhanced sheet processing, making it suitable for high-volume production environments.
Recommended Applications:
- Membrane switch spacers
- Keypads
- Switch mounting
- Graphic overlays
- Circuit layer assembly
- Metal dome placement
- Lead protection
- Die-cut laminations
Usage and Maintenance: Ensure surfaces are clean and dry before applying the membrane switch spacer. Apply with firm pressure to achieve maximum adhesion. Store the product in a cool, dry place away from direct sunlight to maintain its properties. The high-performance adhesive and durable liner make this spacer suitable for long-term use in demanding switch applications.
