Introducing the RFI / EMI Shielding Paint Range from MG Chemicals

RFI (Radio Frequency Interference) and EMI (Electromagnetic Interference) is essentially noise. Noise is any unwanted signal that interferes with intentional signals. If you are having a conversation in person, you can move to less noisy areas but this is harder for telecommunications since EM waves travel fast and easily in many different directions. Electronic devices and equipments need to be shielded from RFI / EMI Interference for telecommunications, technological, and health reasons. These reasons are the basis for both governmental, industrial, and commercial shielding requirements.

RFI / EMI protective lacquers are coatings with electrically conductive materials such as aluminium, copper and zinc impregnated within the blend and are used on non-conducting composite casing materials to shield sensitive electronic devices from radio frequency electromagnetic interference.

The range of applications  for the carbon, graphite, silver and nickel conductive coatings includes cell phones, PDA’s, other consumer electronics, telecommunication equipment, industrial equipment, medical devices, military devices, and aerospace equipment. It can also works well on drywall, and can be used to shield entire rooms.

Canadian based company, M.G. Chemicals, offer a range of RFI / EMI Shielding coatings which offer state of the art protection to electronic circuits.

About Dr Lee Hitchens

Dr Hitchens has been working in the electronics industry and the area of conformal coatings for over 25 years in various areas including sales and technical support. He has also been training people for almost the same amount of time in all areas of conformal coating whether that is materials & equipment selection, process development or troubleshooting to help them solve their particular problem. Recently, he decided that the industry needed a specific place where all of the useful knowledge on conformal coatings could be collated for users to find easily and use in their own production process. So, Nexus was born and he began the Nexus eBook project.
