Part of the Fundamental Manufacturing Processes Video Series, this program begins with an introduction to the basic elements of all paint formulations: pigments, additives, solvents and resins.
The two types of resin polymer structures, enamels and lacquers, are explained with an emphasis on the crosslinking aspect of enamels. The liquid paint section examines both solventborne and waterborne high solids paints, and their type of liquid fluidization, including either: solution fluidization, dispersion fluidization, or emulsion fluidization.
The process of applying liquid paints is broken down into three fundamental sequences: part pretreatment and cleaning, paint application, and paint curing. The paint application processes detailed include: conventional air spraying, airless spraying, air-assisted airless spraying, high volume, low pressure spraying, electrostatic spraying, and electrocoating. The powder coating section fully examines the various process sub-systems, including: pretreatment methods to prepare the part surface for coating, the various application systems to apply the powder, spray booths and powder recovery systems, powder curing, and part transport systems to move parts through the process.
