Water-repellent refers to a material's ability to resist the penetration of water. This property is often achieved through special treatments or coatings that create a barrier on the surface. Common examples of water-repellent materials include certain fabrics, like those used in rain jackets, and surfaces like wood that have been treated to prevent moisture absorption. When a material is water-repellent, it does not become saturated with water, allowing it to remain dry and maintain its integrity. This feature is useful in various applications, from outdoor gear to construction materials, helping to protect against water damage and prolonging the lifespan of products.
