Vedenhylkivinä

Vedenhylkivinä is a Finnish term that translates to "water-repellent" or "water-repellent material" in English. It refers to substances, coatings, or fabrics that exhibit hydrophobic properties, meaning they resist wetting by water. This resistance is typically due to a low surface energy.

Materials can be made water-repellent through various methods. Natural examples include the waxy coating on leaves or feathers. In manufactured goods, water repellency is often achieved by applying chemical treatments or using specialized synthetic fibers. These treatments can alter the surface tension of the material, causing water droplets to bead up and roll off rather than being absorbed.

The applications of water-repellent properties are widespread. In textiles, it's used for outdoor clothing, tents, and umbrellas to keep wearers dry. In construction, it can be applied to building materials to prevent water damage and improve durability. It's also found in coatings for electronics, automotive parts, and even everyday items like shoes and bags to protect them from moisture. The effectiveness of vedenhylkivinä can vary, ranging from a light resistance to complete impermeability to water.
