Water-borne barriers have become essential in various industries due to their unique properties and environmental benefits. These barriers are primarily coatings, films, or structures designed to prevent the penetration of water or moisture into a substrate or system. They are formulated using water as a solvent, making them eco-friendly alternatives to traditional solvent-based systems. This document delves into the significance, types, applications, and future potential of water-borne barriers. Water-borne barriers are critical for industries where moisture management is crucial. They serve as protective layers that extend the life of materials, enhance performance, and reduce the need for frequent maintenance.
