Which polymer is used in the manufacture of paints and lacquers?
(D) Glyptal is used in the manufacturing of paints & lacquers.
This question asks about the polymer used in paints and lacquers. The correct answer is Glyptal.
Glyptal is a type of polyester resin. It is formed by the condensation polymerization reaction between two monomers:
The reaction involves the elimination of water molecules, forming ester linkages and creating a cross-linked, three-dimensional polymer structure.
Glyptal possesses specific properties that make it ideal for surface coatings:
Polymerization: The process of combining small molecules (monomers) to form a large molecule (polymer). The reaction for Glyptal is a condensation polymerization, which can be generalized as:
Acid + Alcohol → Ester + H
Key Properties of Polymers: The application of a polymer depends on its properties like tensile strength, elasticity, chemical resistance, and thermal stability, which are determined by its molecular structure and intermolecular forces.
