Aqueous coating is the most popular film type coating.

• A. False
• B. Not sure
• C. Both
• D. True

Answer: (D)

Aqueous coatings have become the standard for film coating because they use water as the solvent, which greatly reduces health, safety, and environmental concerns compared with organic solvent systems. This makes manufacturing safer and easier to regulate, and it lowers solvent handling and disposal costs. Modern film coatings use polymers like HPMC and other cellulose derivatives that form smooth, uniform films in water-based dispersions, drying quickly in typical coating equipment. The combination of safety, cost efficiency, and reliable film-forming performance explains why aqueous coating is the most commonly used film coating type today. Organic solvent–based coatings exist but carry higher hazards and regulatory burdens, so they are less widely used.
