 Organic coatings are polymers and resins,
produced either naturally or synthetically,
usually formulated to be applied as liquids
that dry or harden as thin surface films on
substrate materials.
 These coatings are valued for the variety of
colors and textures possible, their capacity to
protect the substrate surface, low cost, and
ease with which they can be applied.

 Binders, which give the coating its properties
 Dyes or pigments, which lend color to the
coating
 Solvents, to dissolve the polymers and resins
and add proper fluidity to the liquid
 Additives

 Composition of the coating liquid
 Required thickness of the coating
 Production rate and cost considerations
 Part size
 Environmental requirements

 Phosphate coat applied by dipping,
 Primer coat applied by dipping,
 Color paint coat applied by spray coating, and
 Clear coat (for high gloss and added
protection) applied by spraying.
