Understanding the Answer
Let's break down why this is correct
Answer
The automotive industry is the main user of condensation polymers for durable, weather‑resistant coatings. These polymers, such as polyester and polyurethane resins formed by condensation reactions, create hard, UV‑stable layers that protect car bodies from corrosion and sun damage. Manufacturers use them in clear coats and primers that must withstand rain, heat, and road salt. For example, a polyester‑based clear coat on a new sedan remains shiny after months of exposure to sun and rain, showing the polymer’s effectiveness.
Detailed Explanation
Construction uses condensation polymers, such as polyurethanes, to make coatings that stay strong and resist rain and sun. Other options are incorrect because Food packaging mainly uses thermoplastic polymers like PET, not condensation polymers for coating; Automotive coatings use blends of polymers, but the key protective layer is often an epoxy or acrylic, not a condensation polymer.
