There is a whole range of polyesters made from different acids, glycols and monomers, all having varying properties. Unsaturated polyester resin is the most common type of resin, and it has double bonds in its backbone (main carbon chain). There are several 1.2.1.1 Alcohol Components monographs and reviews on unsaturated polyesters The most common alcohol components are 1,2- and unsaturated polyester resins [1–7]. Unsaturated polyester resin stands up very well to extreme weather conditions like snow, ice, strong winds, rain as well as high temperatures and UV rays. . Carleton Ellis introduced the idea for the combination in the 1930’s. Furthermore, there was an increase in the level of polymerization close to 100% with microwave curing – without the need for post-curing at high temperature. These resins also have workable and resultant properties that make them highly amenable to composite structures like fibreglass. Unsaturated polyester resins are mainly used in the production of fiber reinforced plastics and filled plastic products, including sanitary-ware, tanks, pipes, gratings, and high performance components for the marine and transportation industry such as closure and body panels, fenders, boat hulls/ decks and other large glass fiber reinforced plastic articles.
