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.

Answer 2

To solve the problem, we need to identify the polymer used in the manufacture of paints and lacquers.

1. Understanding the Polymers:

Melamine is a polymer primarily used in the production of resins and coatings, but not typically in the manufacturing of paints and lacquers.
Glyptal is a polymer made from the reaction of phthalic anhydride and glycerol. It is used extensively in the manufacturing of paints and lacquers due to its good adhesion properties and durability.
Nylon 6 and Nylon 6,6 are synthetic polymers used mainly for textiles and plastics, not in the manufacture of paints and lacquers.

2. Identifying the Correct Answer:
The correct polymer used in the manufacture of paints and lacquers is Glyptal, which corresponds to Option B.

Final Answer:
The correct answer is Option B: Glyptal.
