FACTORY APPLIED POWDER COATING OF NON-CONDUCTIVE SUBSTRATES
This section includes Cadillac Coatings Canada Inc.'s guide specification for powder coating non‑conductive materials. The powder coating equipment used, Paintline, has been patented in the United States and Canada by Cadillac Coatings Inc.. The Paintline equipment electrostatically sprays powder onto substrates and melts with IR and cures with UV without VOC's (volatile organic compounds) or off-gassing. The process takes two to ten minutes from 'start to stacking' at about 1.5 - 7.5 metres per minute (5 – 25 feet per minute) depending on substrate, colour, and density; reducing costs and delivery schedules (ideal for sheet goods, panels, and long boards). In order to meet Paintline specifications, maximum material dimensions that may be processed for powder coating are 1524 mm (5 feet) width, 76 mm (3 inch) height, and 6096 mm (20 feet) length.
1.1 SUMMARY
1.1.1 This Section specifies the requirements for powder coating non‑conductive substrates such as medium density fibreboard (MDF), composite woods, oriented strand board (OSB), high density fibreboard (HDF), other composite paneling, magnesium board (MGO), cement board, and other non‑metallic and non‑conductive materials.
