ABSTRACT:
A method is described wherein a compound containing amine functionality is reacted in its liquid form with carbon dioxide to convert the compound into a solid amine carbamate salt for use as a blocked amine curative in powder coating manufacturing and resulting powder coating operations. The blocked amine curative decomposes on heating and reverts back to a liquid amine providing a highly reactive curative and flow modifier for powder coating applications.
