Abstract
The mechanical properties of coating resin on stainless steel were measured by SEM, FT-IR spectra, tensile properties, mole ％ of [NCO/OH], and particle size analyzer. Growing concerns in the environment-friendly coating resin, we have synthesized the solvent-free coating resin to be coating on metals such as stainless steel. The properties of the synthesized coating resin to be contained polyols, MDI, silicone surfactant, fillers and vegetable oil(castor oil), that they have highly stronger in intensity and longer durability than general coating resin of polyurethane resin on stainless steel. The rigid segments of polyurethane in mechanical properties of coatings were due to unsaturated vegetable oil and the increase mole % of [NCO/OH]. In conclusion, the coating microstructure with castor oil can be good material for coatings of anticorrosion of metal substrates such as stainless steel.
