| titleOfInvention | Catalysts for use in preparing polyurethane compositions and methods for curing said compositions |
| abstract | A catalyst, suitable for use in polyurethane compositions comprises the reaction product of: (a) the reaction product of a titanium, zirconium, hafnium or aluminium orthoester and a <beta>-diketone or <beta>-ketoester and (b) a complexing agent selected from a mercapto compound, an oxazolidine or a tetrahydro-oxazine. The catalyst is particularly useful for preparing coating compositions which have a long pot life and can be cured at room temperature. A catalyst for use in preparing polyurethane composition comprising the reaction product of: (a) the reaction product of a titanium, zirconium, hafnium or aluminium orthoester having the formula M(OR)4 or A<arrow down>(OR)3, in which M is titanium, zirconium or hafnium and R is an alkyl, cycloalkyl or aryl group containing 1 to 8 carbon atoms, and a <beta>-diketone or <beta>-ketoester having the general formula where R1, R2 and R3 may be independently selected form the group consisting of hydrogen and alkyl, aryl, cycloalkyl, alkoxy, aryloxy, hydroxyalkyl, alkoxyalkyl and hydroxyalkoxyalkyl groups containing up to eight carbon atoms and in which the molar ratio of orthoester to <beta>-diketone or <beta>-ketoester is in the range 1:0.5 to 1:4, orthoester to <beta>-diketone or <beta>-ketoester; and (b) a complexing agent selected from a mercapto compound or an oxazolidine or a tetrahydro-oxazine having the general formula (A) or (B) respectively in which R10 is hydrogen or an alkyl group and X is a hydroxyalkyl group, or mixtures thereof, and wherein the amount of complexing agent present relative to the reaction product (a) is sufficient to produce a pot life of a hydroxyl polymer/polyisocyanate reaction mixture containing the catalyst of 2 hours or more. |
