Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
Lacquer paints are generally applied on structural steel, are less durable as compared to enamel paints, consist of resin and nitro-cellulose, and contain alcohol as thinner. Lacquer paints are known for their fast-drying properties, high gloss finish, and ability to be applied in thin layers. They are often used on wood, metal, and other surfaces to provide a decorative finish. However, they are less durable than enamel paints, which are more resistant to wear and tear and tend to last longer. Lacquer paints consist of a resin (such as nitrocellulose, acrylic, or polyurethane) suspended in a solvent (such as alcohol or acetone). The solvent helps the paint flow smoothly and evaporates quickly, leaving behind the resin to form a hard and glossy finish.
