Lacquer paints
are generally applied on structural steel
are less durable as compared to enamel paints
consist of resin and nitro-cellulose
contain alcohol as thinner
all the above.
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.

The only place that lacquer paint is used today is in furniture manufacturing shops. It is extremely rare that lacquer paint will be used in auto body and painting shops.

Lacquer paints are soft and do not have many chemicals. Thus, they are not durable or long-lived.
