Coatings are frequently named by the resin from which it is made. Resins that give a coating its name include epoxies, alkyds, urethanes etc. However, there are some other raw materials also which are used to make the coating. Such coating raw material includes pigments, fillers, solvents and additives. Pigments are responsible to provide hiding and colour to the coating. Solvents are volatile component of coating and it is mainly used to improve the ease of applicability by reducing the viscosity of coating while additives are used to improve coating performance.
