Coatings formulated with polyesters can bridge the gap in cost without sacrificing critical end-use properties. In fact, they offer an added benefit of better ease of handling, as most polyesters are lower in viscosity than either a urethane or an epoxy. Recently, new radiation-curable polyesters exhibiting superior abrasion resistance properties have been developed. One, in fact, is low enough in viscosity to make it suitable for spray or vacuum coating application.
