Abstract:
1. A cross-linking composition which comprises (a) an aqueous liquid, (b) a cross-linkable organic polymer, and (c) a solution of a zirconium cross-linking agent which is produced by a process which comprises contacting a zirconium triethanolamine complex having a molar ratio of 1:2 to 1:5 of zirconium to triethanolamine with a mixture of polyols, which mixture comprises a hydroxyalkylated diamine and a hydrocarbon polyol wherein the molar ratio of zirconium to hydroxyalkylated diamine is 1:0.5 to 1:1 and the molar ratio of zirconium to hydrocarbon polyol is 1:0.5 to 1:1.5 and wherein the cross-linking composition has a cross-linking rate of 5-7 minutes generating viscosity in the range of 500 to 1000 centipoise (cp) after 90 minutes at pH 10 by simulation in a FANN viscometer at 275° F. (135° C.) and 212 rpm at 100 reciprocal second of shear.
