The abundance and widespread use of paint in our daily lives makes it easy to take paint for granted. A look at the chemistry of paint leads to a better appreciation of its complexities.
Paint is a liquid composition that dries to an opaque film.
Paints are generally classified as either solvent-borne or waterborne. Waterborne paints use water. Waterborne wall coatings prevailed from prehistoric cave paintings up to medieval wall paintings. Natural proteins were used as binders for the pigments. But all these exhibited poor washability and durability.
