OXIDATIVELY CURABLE COATING COMPOSITION

摘要

The present invention relates to an oxidatively curable coating formulation comprising an oxidatively curable alkyd-based resin and a bis-triazacyclononane-based chelant, which chelant may optionally be complexed with a suitable transition metal ion, particularly manganese. The formulations may be paints or other oxidatively curable coating compositions. The invention also provides methods for making such formulations and compositions resultant from the curing of such formulations.

主权项

1. A formulation comprising an oxidatively curable alkyd-based curable resin and a complex of a chelant of the formula (I): (wherein:
each R is independently selected from hydrogen, C1-C24alkyl, CH2CH2OH, CH2COOH and pyridin-2-ylmethyl;Q is a C2-C6alkylene bridge, a C6-C10 arylene bridge or a bridge comprising one or two C1-C3 alkylene units and one C6-C10 arylene unit, which bridge may be optionally substituted one or more times with independently selected C1-C24 alkyl groups; andeach R1, R2, R3, and R4 is independently selected from H, C1-4alkyl and C1-C4alkylhydroxy) and a transition metal ion selected from the group consisting of ions of manganese, iron, cobalt, vanadium and copper, wherein the complex is not well-defined.
