   en.wikipedia.org/wiki/List_of_polyurethane...

   Boat decks and outdoor marine surface areas. Some boat decks including U.S Navy and Pakistani fishing vessels use specialized polyurethane sealants to protect from constant moisture and harsh oceanic elements. As an example, Durabak-M26 uses a custom single-part polyurethane to prevent water seepage to unwanted areas. Water tanks

3. Self-cleaning surfaces - Wikipedia

   en.wikipedia.org/wiki/Self-cleaning_surfaces

   A) A superhydrophobic surface with a high contact angle nearing 180 degrees. B) A surface with a low water sliding angle. C) A surface with a higher sliding angle which will be less efficient when self-cleaning water from its surface. Control over surface wettability is a critical aspect of self-cleaning surfaces.

7. High-density polyethylene - Wikipedia

   en.wikipedia.org/wiki/High-density_polyethylene

   High-density polyethylene ( HDPE) or polyethylene high-density ( PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. [1] With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes ...
