Answer:- When the medium(solvent) that carries paint resins, pigments, and additives is an oil, enamels are called oil-based, and when its water, they are called water-based. Also, the resin used differs from the solvent. Oil-based enamels produce hard, durable, and glossy layers. However, oil-based paints take a longer time to dry. While water-based enamels dry quicker, they produce a less glossy finish than traditional oil-based ones.
