<p>A combination of chemicals suitable for extending pot life and shortening cure time of a pot mix of a thermosetting composition is disclose d. The combination of chemicals includes a catalyst, such as, dibutyl tin dilau rate; carboxylic or sulfonic acid; and an extender compound, such as 2,4 pentanedi one.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 varie ty of substrate surfaces while still producing coatings that cure quickly upon application.</p> |
