3M™ Tape CN4490 is a unique, double-coated conductive tape that functions as a thin, repositionable gasket material. It is constructed from a non-woven copper-nickel fabric and features a double-coated acrylic conductive adhesive. At only 2.0 mils thick, it is one of the thinnest options available, providing excellent shielding, grounding, and static dissipation for compact electronic assemblies.
3M™ Metallized Cloth CN4490 Features:
Backing: Non-woven copper-nickel fabric.
Adhesive: Double Coated Acrylic Conductive.
Total Thickness: 2.0 mils (0.05 mm).
Key Characteristics: Thin, lightweight, conformable, and acts as a repositionable conductive gasket.
3M™ Metallized Cloth CN4490 Applications:
Primary Use: Creating thin, conductive, repositionable gaskets between components.
Secondary Use: EMI shielding, grounding, and static dissipation in applications requiring a double-sided adhesive.
Ideal For: Attaching shielding cans to PCBs or grounding components to a chassis.
