Question

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

• A. Melamine
• B. Glyptal
• C. Nylon 6
• D. Nylon 6,6

Hint:

When choosing materials for specific applications like paints, consider properties like drying time, durability, adhesion, and finish quality.

Answer 1

The Correct Option is B

Step 1: Understand the properties of Glyptal.

Glyptal is an alkyd resin formed from the esterification of glycerol and phthalic anhydride. It is particularly valued in paints and lacquers for its ability to form a film that dries quickly, provides a robust and durable finish, and adheres well to metal surfaces.

Step 2: Evaluate the other options.

• Melamine, a nitrogen-rich resin, is typically used in laminates and coatings but not primarily in paints.
• Nylon 6 and Nylon 6,6 are polyamides mainly used in fibers and plastics rather than in paint formulations.

Conclusion: Given its specific use in the paint industry for its desirable properties, Glyptal is the correct answer.
