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