Question

Waterproofing is the process of making an object or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions. A garment described as waterproof will have a water-repellent coating. For example, a rain coat. The waterproofing coating changes the angle of contact from acute to obtuse, in this way, water beads up on the surface and does not easily penetrate the clothing. Value of angle of contact lies between​
