Coloured coatings shield all over
ACT has introduced a new range of coloured shielding coatings, designed to be sprayed through vents, apertures etc and remain undetected.
They offer many advantages over alternative methods of shielding, including their relatively shorter manufacturing lead-times, and the ability to coat selectively.
Paints can be made conductive by adding nickel, copper or silver particles to the resin.
Traditionally nickel paints were specified for low-cost/low-performance applications.
For high levels of shielding, silver is normally specified.
However these coatings are considerably more expensive than copper or nickel paints.
Applicoat EC225 provides an order of magnitude better shielding than nickel paints.
However as the applied thickness is less than half that of nickel, processing and material costs are reduced and hence the applied cost of the coating is significantly reduced.
Applicoat EC225 also offers other benefits; it is formulated using alcohol-based solvents and hence has minimum impact on the intrinsic properties of the substrate.
ACT specialises in the application of shielding and decorative coatings onto plastic substrates.
The company also offers vacuum deposited and electroplated coatings for EMI/RFI shielding.
