Abstract
A method of curing a powder coating composition comprises reacting a polyester resin with an alkanolamine derivative of titanium or zirconium. This derivative is the reaction product of an orthoester or a condensed orthoester of titanium or zirconium with a trialkanolamine and with a dialkanolamine or a monoalkanolamine. In the reaction product the ratio of trialkanolamino radicals to Ti or Zr atoms is from 0.5:1 to 1.5:1 and the ratio of monoalkanolamino radicals or dialkanolamino radicals to Ti or Zr atoms is from 0.2:1 to 2.0:1. The reaction products are preferably derivatives of ethanolamines or isopropanolamines and can be used to cure carboxyl-rich resins or hydroxyl-rich resins.
