Water and oil repellents are substances that can prevent liquids from adhering to surfaces.
They are commonly used to make fabrics, coatings and surfaces hydrophobic or oleophobic, meaning they can repel water and oil. This can help to protect against stains,
corrosion and other damage caused by liquids.
Water and oil repellents are used in a variety of applications, including clothing, footwear, electronics, and construction materials.
Some common water and oil repellents include waxes, silicones, fluorocarbons and nanotechnology-based coatings.
