Conductive coatings consist of a metallized layer deposited through thin film (evaporation or sputtering), plating, or thermal spray processes. They are applied to enclosures that house electronic components in order to provide shielding against electromagnetic interference (EMI) and radio frequency interference (RFI). Conductive coatings are also used to provide dissipation and control of electrostatic discharge (ESD). Polymer-based coatings with metal or conductive fillers are suitable for both EMI shielding and static control. Circuitry and antennas can be formed on dielectric substrates by using lithography, screen printing, or other patterning methods to apply the conductive coating material. Materials with a combination of conductivity and high relative magnetic permeability are the most effective in EMI shielding. Products & Services
Coating services coat or plate the surfaces of manufactured components. Coating processes include ceramic, coil, dip, dry lubricant, phosphate, powder, rubber, thin film, titanium, and selective coating. Coating services also perform chemical finishing, galvanizing, hardfacing, painting, thermal spraying, and screen printing.
Resurfacing, recoating and refinishing services alter or restore damaged coatings and surfaces to a usable condition.
Web coating services apply a layer of resin or other liquid coating to the surface of a continuous sheet of material.
Specialty coating and finishing services perform specialized or proprietary coating and finishing processes.
Industrial painting services apply paint to substrates for protection and/or decoration. They perform processes such as coil or roll coating, dip or immersion coating, dry lubricant coating, powder coating, and web coating.
