Industrial materials and thermal power stations are coated with______________________?
Correct answer: B. Epoxy paints
- A. Polyester resins
- B. Epoxy paints
- C. Polyamide resins
- D. Polyvinyl chloride
Explanation
Epoxy paints are used to coat industrial materials and thermal power-station equipment because cured epoxy polymers adhere strongly and resist chemicals, heat and corrosion. Polyester resins may also provide coatings, but the stated industrial protective coating is specifically associated with epoxy paints.

About Polymers
Polymers are large molecules made from repeating monomer units joined by covalent bonds. The topic distinguishes addition polymers such as polyethylene, PVC and polystyrene from condensation polymers such as nylon and polyester, and relates chain structure to thermoplastics, thermosetting polymers, elastomers, properties, uses and environmental concerns.
