Abstract
Disclosed is a catalyst system which improves the cure time of acid-catalyzable resole resins while providing extended shelf life thereof. Broadly, the present invention includes a method for formulating an acid-catalyzed, non-aqueous resole resin composition and to the composition itself. The catalyst system comprises an acid catalyst and an oxidizing agent in an amount adequate for cure in at least about the same time that occurs by use of at least twice the amount of said acid catalyst alone. The shelf life of the catalyzed resole resin is greater with the inventive catalyst system than with an equivalent resole resin containing only the acid catalyst in twice the amount.
