Abstract
Over the last few years, UV radiation curing has become a well established coating technology used for several different applications. Polymeric component based on renewable resource is another area for getting low VOC coatings. In the present study cellulose and soya fatty acid were used to prepare oleochemical polyols which in turn reacted with diisocyanates to get PU which is further reacted with hydroxyl terminated acrylates to get oligomeric urethane acrylates. These polymeric compounds are used without any organic solvent for UV-coating formulation and cured by UV light on the metal surfaces. Thus effect of different types of polyols were used to prepared UV coatings studied on thermal properties like dynamic mechanical properties (DMA) and thermogravimetric analysis (TGA)
