1.) Coating is a covering that is applied to the surface of an object [substrate]. Coatings are applied to improve surface properties of the substrate, such as adhesion, appearance, wet-ability, corrosion resistance, wear resistance, and scratch resistance. Coating may be applied as liquids, gases or solids.
However, painting is the practice of applying paint, colour, pigment, or other medium to a surface. Paintings may have surfaces as walls, paper, canvas, wood, glass, lacquer, clay or concrete for support.

2.) Binder: Binder is a substance which is used to make other substances, substrates or materials mix or stick together.

Different types of coating are:

Protective Coating
Industrial coating
Architectural Coating (polymer coating)
Special purpose Coating (Automotive Refinish Coatings, Industrial Maintenance Coatings)

Varnish: Varnish is a clear transparent hard protective finish or film. It can also be defined as resin dissolved in a liquid for applying on wood, metal, or other materials to form a hard, clear, shiny surface when dry.

Primer or undercoat: A primer/undercoat is a preparatory coating put on materials before painting. Primer/undercoat ensures better adhesion of paint to the surface. It increases paint durability.
