"RFI" is an acronym for Radio Frequency Interference, while "EMI" stands for Electromagnetic Interference. These types of signals are emitted by many common items such as power supplies, electric motors, switches, relays, and even fluorescent lights.
Radio wave and electromagnetic interference can affect both the device which is emitting the signals as well as other equipment in the vicinity. Especially in today's electronic "wireless" world, this can cause havoc if the radio or electromagnetic signals from one piece of equipment are interfering with the functioning of another.
FI/EMI Shielding does exactly what the name implies: it shields equipment from these harmful signals, thus allowing it to function without interference. The shielding is provided via a coating to all critical areas of the components that emit RFI and EMI waves. The coating can be done via a spray-on acrylic based coating, as a liquid paint or a brush-on coating.
Atlanta Metal Coating, Inc. offers RFI / EMI Shielding using Nickel, Copper and Silver. These pure metals, in our formulated coating, can help to reduce and even completely remove RFI and EMI interference waves.
Atlanta Metal Coating offers custom wet painting in small, medium and large projects and for virtually any size parts. We can handle proto-type work, smooth and textured paint jobs, and can meet all requirements on any Mil-Spec painting job as well.
Powder Coating is the technique of applying a protective and attractive finish to an item or component, and can be used on a wide variety of items as it works well on many different materials. The powder is made of a complex mixture of pigments, resins and chemicals, and is electromagnetically charged.
The process applies dry paint to an object, rather than traditional liquid paint. The powder is electromagnetically charged, and so will adhere to the grounded surface. Because wet paints must dry in order for their final look to become evident and their durability to be tested, Powder Coating offers a viable alternative as the outcome can be more controlled. Powder Coating is cured rather than dried, and so it's not weather and humidity dependant for final finishing. The curing process in the oven causes a chemical reaction in the powder coat which gives it the strength and durability, while the heat causes the micro-granules to melt and form a continuous coating.
Thermoplastic powders will re-melt when heated while the Thermosetting powders will not re-melt. During the curing process, a chemical cross-linking reaction is triggered at the curing temperature and it is this chemical reaction which gives the powder coating many of its desirable properties.
A complete coating system is available in a variety of chemistries, colors, gloss ranges, textures and metallics and may include a primer, the coating, and a sealant/top-coat.
