ABOUT EMI SHIELDING
EMI Shielding Coatings & Conductive Form in place gaskets are materials designed to contain, shield or control an Electronic Field in order to prevent undesired responses or degradation of performance in electrical or electronic equipment. EMI Shielding Coatings are used by the medical, military, telecommunications automotive, consumer goods and instrumentation markets and industries. Whether you are shielding the interior of an electronic enclosure or components with in the electronic enclosure, Central Coating has the expertise and experience to provide the appropriate and most cost effective solution to your EMI Shielding problem.
Depending on your application and EMI Shielding requirements, Central Coating offers a wide selection of EMI Coatings which we stock. These coatings include Silver Plated Copper, Nickel and pure Silver materials. We also apply a wide variety of Conductive Form-in-place gasket materials if your application requires gasket sealing solutions. Many of these materials’ technical data sheets can be found in the Technical Section of our web-site.
When shielding a system, design engineers should consider incorporating a Faraday Cage design approach from the onset of the design. This approach will provide enclosure shielding encapsulating the electronics. Additional shielding can be added to those areas which are EMI “Noise” generating. When utilizing a plastic enclosure, conductive EMI shielding paints in combination with form-in-place conductive gasket application have proven to be great shielding approaches which simulate Faraday cages. The EMI Shielding Coating would be applied robotically to the interior of the plastic enclosure and the EMI Form-in-Place (FIP) conductive gasket would provide the connection and complete the seal. Central Coating can help you choice the appropriate EMI Shielding Coating as well as EMI Shielding Gasket material for your application.
With over 35 years of experience, Central Coating has a solid history of proving our customers with quality, cost effective and reliable EMI Shielding coating solutions. We remain in the forefront of technological advances in precision coating application for a growing technological community. We have over 35,000 square feet of manufacturing space, 5 Robot Coating Cells and 3 six axis robots applying EMI Shielding Coating 1 part to thousands of parts. Central Coating can meet all of your EMI Shielding coating application needs. Please browse our site for other services including water transfer printing.
What’s New for EMI Shielding Applications at Central Coating
Central Coating is now using two new material for emi shielding applications:
The first compound is ideal for use on electronic enclosures and assemblies where abrasion resistance and coating durability are important. This durable, conductive coating derives its hardness from its nickel composition and may provide limited amounts of H-field shielding. Given its relatively low conductivity as compared to other metal fillers, the nickel provides exceptional shielding for enclosures where both external RF fields must be excluded, and internal radiated emission must be attenuated.
It is an electrically conductive, one-component nickel-filled acrylic coating that is specially formulated for application on plastics to provide modest EMI shielding. The benefits include:
- Good EMI shielding performance at standard thickness and application
- Good adhesion to a variety of substrates
- One component, ready to use with simple mixing
- Good environmental and abrasion resistance
- Good leveling. Wets and covers surfaces smoothly.
- Easy to apply with standard spray paint equipment
- Standard dry-times for efficient, costeffective application
- Good electrical conductivity and cost effective addition to electronic enclosures and assemblies
This conductive coating is ideal for a variety of applications, including:
• Moderate EMI shielding
• Anti-static protection
• Surface grounding
• Coating of ABS, PC/ABS, and many other types
of plastic enclosures
The second material we are working with is an electrically screen-printable, electrically conductive, epoxy based ink and coating suitable for application by screen- printing, dipping and syringe dispensing. This product features excellent adhesion to Kapton, Mylar, glass and a variety of other surfaces. Unlike conventional conductive materials, this product is very resistant to flexing and creasing. Some applications for this include printed potentiometers, printed resistors, emi/rfi shielding of polyimide flexible circuits, polymer thick film circuitry, membrane switches and anode coatings for tantalum capacitors.
