The surface is coated with a “hydrophobic” material that repels water. Hydrophobic materials (literally “afraid of water” or “against water”) repel water as a result of their chemical makeup. The repulsion can be chemical or a matter of their structure.

Those products are coated with something called a “hydrophobic” coating. Hydrophobic means “water hating” in Greek. These coatings repeal water. This means that anything with water in it won’t be able to stick to them at all, but will just roll off instead.
