Identify the use of glyptal

Step-by-step solution

Glyptal is a polyester resin synthesized via condensation polymerization of ethylene glycol and phthalic acid. As a thermosetting polymer, its primary application is in the manufacture of paints and lacquers due to its superior adhesive and flexible properties, though it is also used in binding materials and certain molding compounds. Among the given choices: Option A involves electrophoresis gels, typically composed of agarose or polyacrylamide. Option B corresponds to paints, aligning with glyptal's predominant u
