Thermoplastic coatings flame spraying

Powder coatings are applied by thermoplastics powder flame spraying or electrostatic powder spraying. In most cases, electrostatic powder spray systems are more versatile. An electrostatic charge is appUed on the substrate and an opposite charge is appHed to the powder in the spray head (gun). A coating film forms after heat-fusion.
