Which polymer is used in the manufacture of paints and lacquers?

(A)Glyptal✓ Correct
(B)Polypropene
(C)Poly vinyl chloride
(D)Bakelite

Answer: (A)

Solution

Glyptal is the polyester made by condensing ethylene glycol with phthalic acid, and its excellent film-forming quality is exactly what paints and lacquers need. The others serve elsewhere -- polypropene in ropes and moulded goods, PVC in raincoats and pipes, bakelite in electrical fittings -- so glyptal is the paint resin.
