【Abstract】 Pyridine catalyzed copolymerization and cross-linking reactions of car-danol-formaldehyde resin with toluene 2,4-diisocyanate ( TDI ) and factors influencing the reactions have been investigated. The coating resulted is characterized by light-colour and high hardness. Its flexibility and property of chemical-resistance can be improved largely by addition of a little of castor oil to the reacting mixture.更多还原
