Thermosetting acrylic emulsion for coating -A literature review

In this paper a review of various methods of synthesis of acrylic emulsion coatings are mentioned. When a coating is applied to a substrate, solvent evaporates from the liquidphase resulting in the formation ofa film. If the solvent used is organic solvent the volatile organic compound (VOC) emitted may prove to be an environmental hazard. But if water is used as a solvent instead of the organic compound, then the VOC emitted to the atmosphere is negligible. With growing environmental awareness and stringent laws being formed, the future of the coating industry depends on paint systems that emit minimal VOCs or no VOCs. The market study presented towards the end of this paper also indicates that there is a decrease in the market of solvent based coatings while there is a sharp increase in the market for water based coatings particularly acrylic coatings. The main objective of the review is to describe the acrylic polymer coating synthesis in detail based on the knowledge available in the open literature.
