EMI shielding specialist Central Coating Co. Inc. has released two new materials for EMI shielding applications.
The first material is an electrically-conductive, one-component, nickel-filled acrylic coating ideal for application on plastics to provide modest EMI shielding and anti-static protection for electronic enclosures and assemblies where abrasion resistance and coating durability are important. With its relatively low conductivity as compared to other metal fillers, says the company, the nickel provides exceptional shielding for enclosures where both external RF fields must be excluded, and internal radiated emission must be attenuated.
The second material is an electrically screen-printable, electrically conductive, epoxy based ink and coating suitable for application by screen printing, dipping or syringe dispensing. Unlike conventional conductive materials, this material is very resistant to flexing and creasing and offers excellent adhesion to Kapton, Mylar, glass and a variety of other surfaces. Ideal applications include printed potentiometers, printed resistors, EMI/RFI shielding of polyimide flexible circuits, polymer thick film circuitry, membrane switches and anode coatings for tantalum capacitors.
