Waterborne Coatings : An Alternative of Conventional Coatings

Abstract

A major objective of research and development in the area of surface coatings, is either reduce or eliminate the presence of organic solvents present in conventional coating systems or to replace them with certain environmental favorable solvent such as water in the case of waterborne coatings. The increasing cost specially of petroleum products, environment, energy etc. have increased pressure on paint manufacturers to produce the ideal system which does not contain toxic substances and does not contribute to environmental pollution; has a low raw material cost; provides the necessary protection to the substrate high performance and can easily be repainted. The solvents play a variety of important role in resin manufacture, coating production, application, and film formation. Substantial research efforts are being exerted to reduce and, in at least some cases, eliminate the need for solvents
