Abstract
NCO terminated polyurethane prepolymers were synthesized from isophorone diisocyanate(IPDI), poly(tetramethyleneglycol)(PTMG) and dimethylol propionic acid(DMPA). Subsequently, aminosilane terminated prepolymers were prepared by capping the NCO groups of polyurethane prepolymers with different moles of aminopropyl triethoxysilane(0~0.02 mole) as a coupling agent. The average particle size of the silylated polyurethane solutions increased with increasing APS content. Also, the prepared coating films showed better thermal stability and pencil hardness than pure waterborne polyurethane.
