Photo-polymerization is an applicable method to produce a polymeric network from liquid resin systems. Among different existing techniques, UV-curing is more common because of reduced energy consumption and less equipment costs. The important limitation for use of UV-curing systems is the coating of 3D subjects or high pigmented coatings. In these applications the whole area of coating is not illuminated and sufficient cure does not achieved. In order to overcome such problem, a second curing system is applied. The most usual method is the use of thermal curing along with UV irradiation. The final coating properties, however, are obtained by the combination of a UV-curing process and a chemical crosslinking process. The cured films are usually more flexible and adhere better to the substrate than 100% UV-curable systems, presumably because shrinkage is reduced. The most common coating type is two-component urethane-acrylate, where an acrylic polyol (with polyester acrylate structure) solution is mixed with a polyisocyanate just before use and applied to the substrate. In this study, different samples were made from polyester polyol, isophorone diisocynate (IPDI) and 2-hydroxy ethyl methacrylate (HEMA). Polyester polyols were synthesized in a way that the final coating film has flexibility and surface hardness simultaneously. Final coating films were prepared by various compositions of oligomers, photoinitiators and reactive diluents. Subsequently, for effective curing, different curing conditions (the sequence and order of magnitude for radiation and temperature) were investigated. The mechanical properties of dual-cure coatings such as pendulum and pencil hardness, flexibility and impact resistance were examined.
