The novel ultraviolet (UV) curable waterborne polyurethane dispersion was formulated from 2,4-Tolylene diisocyanate (TDI), hydroxy terminated unsaturated polyesters (HTUP), 2,2-dimethylol propionic acid (DMPA) and Linalool (LL) (a terpineol). TDI has been selected for receiving more thermo resistant coating. LL has been selected for fast curing process. The resultant dispersions were coated on steel panel. The panels were irradiated by UV mercury lamp (15w) for 10-15 minute. The resultant coatings were characterized by thermal and mechanical properties. The results showed that the thermal stability of coatings and mechanical properties is good due to high cross-link density. This might be responsible due to presence of unsaturated polyester segment.
