Electric wire spraying is a technique in which two electrically conductive wires are transported through a spray gun. An electric arc is produced between the ends of the two wires causing them to melt. Compressed air is used to transport the molten material to the substrate where it forms a coating.
This process allows coatings to be applied quickly and at low energy costs. The major benefits of electric wire spraying are its large spraying capacity and excellent adhesion. The equipment can be operated at a low energy costs and it is very mobile making the process suitable for working on location.
