In the present work, polyurethane resins have been synthesized using soybean oil based polyols (> 80% bio-renewable content) as a primary component. To overcome some of the limitations associated with soft and flexible structure of soy-based polyols, the resin has been designed with two unique set of functional groups –OH and acrylate, as a means of crosslinking sites. Such resin system can be cured by two independent cure mechanisms – (a) thermal (or ambient) curing of –OH groups by use of isocyanate cross-linkers, and (b) by UV-curing of acrylate functional groups using appropriate photoinitiators. Thus, this dual-curable system can provide a means to control the degree of curing and hence the thermo-mechanical properties and performance of these coatings. The study shows that dual-cure coatings with high bio-based content can be successfully formulated and that their properties can be varied by controlling the degree of cure reactions.
