NCO terminated polyurethane prepolymers were synthesized from isophorone diisocyanate(IPDI), poly (tetramethylene glycol)(PTMG) and dimethylol propionic acid(DMPA). Subsequently, waterborne polyurethanes were prepared by capping the NCO groups of polyurethane prepolymers with different types of silane coupling agents, such as methyltsimethoxysilane(MTMS), glycidoxypropyl trimethoxysilane(GPTMS), methaeryloxypropyl trimethoxysilane(MPTMS) and aminopropyl triethoxysilane(APS). The avenge particle size of the waterborne polyurethane solutions was increased by adding silane coupling agents. Also, the coating films prepared from GPTMS, MPTMS and APS, exhibited better pencil hardness than those from pure waterbome polyurethane. On the other hand, the coating films from MTMS did not show an improved pencil hardness than those from pure waterbome polyurethane.
