Generally speaking, all paint is made up of three components: a pigment, a vehicle, and a solvent.
Pigment is the material that gives paint its color. Pigments can be organic or chemical, but pigments have nothing to do with how the paint is classified.
A paint vehicle is material that bonds to pigment and remains on the surface once the paint dries. The vehicle is what gives paint its protective properties.
A solvent is any liquid that dissolves the vehicle to make paint liquid in the bottle or can. Note that a solvent does not have to be a chemical. Water is a solvent if it dissolves the vehicle in a given paint
Paints can be divided into three groups according to drying or curing mechanism-
Physically drying paints-drying process involves evaporation of solvents.
Oxidative drying paints-drying process combines evaporation of solvents with a chemical reaction between the oil in the paint and the oxygen in the air.
Chemically curing paints-drying process involves chemical reaction between the base and a hardner. The two components must be mixed properly.
A primer is a preparatory coating put on materials before painting a plastered surface. Priming ensures better adhesion of paint to the surface, increases paint durability, and provides additional protection for the material being painted. Primers can usually be tinted to a close match with the color of the finishing paint. If the finishing paint is a deep color, tinting the primer can reduce the number of layers of finishing paint that are necessary for good uniformity across the painted surface. Wood primers are partly penetrative and provide a mechanically adhered base for the undercoat.
Metal primers in general are corrosion inhibiting base coats that adhere specifically to the metal surface, although some metals require more specialized preparation (Galvanized metal, aluminum etc) or to be allowed to weather before painting for better adhesion.
