Beschreibung
Zusammenfassung:	The invention relates to a powder coating based on a carboxyl-functional polyester and an epoxy-functional cross-linking agent. The cross-linking agent is the reaction product of an isocyanate-containing compound and a hydroxyglycidyl ester. The invention also relates to the reaction product of a hydroxylglycidyl ester and an isocyanate-containing compound based on an active hydrogen-containing compound and a polyisocyanate. The invention also relates to hydroxyglycidyl esters with a molecular weight between 132 and 500 and reaction products thereof.
