Answer 1

The correct option is D For sun-shading

Koreseal is a long chain polymer of vinyl chloride $\left(C{H}_{2}CHCl\right)$.

Vinyl polymers are heat, electricity and corrosion resistant and are unaffected by exposure to light or by long storage.

When it is mixed with plasticizers, it is used as wall covering paints for water proofing property; lining material for tanks; also used in wire and cable insulation.
