Paint coatings continued mechanical processes

Coating compounds are used to cover the surfaces of many materials from plastic to paper to fabric to metal to concrete and so on. Many plastics produced are consumed as coating materials, including paints, primers, varnishes, and enamels. Metals may be surface coated to improve their workability in mechanical processing. Substrates protected from different environmental conditions basically include the metals (steel, zinc, aluminum, and copper), inorganic materials (plaster, concrete, and asbestos) and organic materials (wood, wallboard, wallpaper, and plastics). Different technical developments continue to occur in the... 

The mechanical coatings are primarily barrel processed on to parts up to about 150 mm long or 400 g mass. Adhesive bonding (with a conductive adhesive to maintain the electrochemical protection by zinc) is particularly suitable for wrapping pipes. Vapour deposition has some use in products but the newest development is application on continuous strip for car-body manufacture—the surface is smooth so that the subsequently painted surface has no unevenness. 

The free radical oxido-polymerization of unsaturated triglycerides in atmospheric conditions has been (and continues to be) exploited mostly in coating applications involving inks and paints. These systems and the mechanisms they involve represent well-established and well-documented traditional processes [15-17] and will not be discussed any further here, also because, in terms of bulk material properties, the ensuing networks display rather poor mechanical properties.
