Abstract
A combination of chemicals suitable for extending pot life and shortening cure time of a pot mix of a thermosetting composition is disclosed. The combination of chemicals includes a catalyst, such as, dibutyl tin dilaurate; carboxylic or sulfonic acid; and an extender compound, such as 2,4 pentanedione. The combination is generally included in a polymeric component of the urethane composition. The extended pot life provides the user with longer open time during which to efficiently apply a coating of the pot mix over a wide variety of substrate surfaces while still producing coatings that cure quickly upon application.
