thin layers of a waterproof substance on the surface of hydrophilic materials. Hydrophobic coatings are often called water-repellent, which is incorrect, since the water molecules are attracted to the coatings, although extremely weakly, rather than repelled by them.ubstances used as hydrophobic agents include salts of fatty acids and such metals as copper, aluminum, and zirconium; cation-active surface-active agents; and low-and high-molecular-weight organosilicon and organic fluorine compounds.
What are the basic structure of a hydrocarbon and why these molecules are hydrophobic? Hydrocarbons are molecules that consist of JUST carbon and hydrogen. they are mostly fuels, such as propane. (C3H8) Hydrocarbons are hydrophobic (meaning that they repel waterâ¦) is because they are polar.
