Two new electrically conductive acrylic coatings have been released by Chomerics Europe – a division of Parker Hannifin. The coatings are designed for application onto plastic housings to provide EMI/RFI shielding.
CHO-SHIELD 2040 is silver-filled material that provides a shielding performance of > 75 dB and CHO-SHIELD 2044 uses a nickel filler to achieve > 60 dB shielding effectiveness (both between 80 MHz and 10 GHz).
Both coatings are durable and provide high levels of abrasion resistance making them suitable for use in equipment that is likely to be operated in a range of harsh environments.
Able to provide EMI/EFI shielding, anti-static protection and surface grounding, the coatings facilitate the design of a wide range of electronic products and equipment in ABS, PC/ABS and many other types of plastic enclosures and housings.
Both materials have a robust formulation that allows them to be applied using either low or high volume paint application processes using conventional paint spraying equipment.
