Abstract
Disclosed is the preparation of 1,3,5-triazine carbamates which are suitable for use as crosslinking agents in curable compositions, particularly in coating compositions which are capable of curing at relatively low temperatures without releasing formaldehyde during cure. The process includes the step of contacting a 1,3,5-triazine derivative having cyanate-displaceable leaving groups (i.e. cyanuric chloride), a cyanate-containing reagent (i.e. potassium cyanate), and an isocyanate-reactive compound such as an alcohol, in the presence of a polar solvent or in the presence of a non-polar solvent in combination with a phase transfer catalyst.
