What is paint? Give the requisites of a good paint.

Paint is a mechanical dispersion of one or more pigments in a drying oil (vehicle) with a thinner, drier and other additives. When it is applied to a surface, the thinner evaporates and the oil dries to form a thin, hard, protective and decorative film.

Requisites of a good paint

  1. Spreads easily and covers the surface well in a few coats.
  2. Dries within a reasonable time to a hard, tough, elastic film.
  3. The film is smooth, glossy and adheres firmly (no cracking or peeling).
  4. Resists weather, water, chemicals and heat.
  5. Has a stable, non-fading colour.
  6. Non-toxic, has no bad smell, and is economical.
