Abstract
A method of crosslinking an oxidative polymer having oxidatively crosslinkable functional groups and a two-pack composition used therein is provided. The oxidatively crosslinkable functional groups on the oxidative polymer are crosslinked by contacting the oxidative polymer with a catalytic amount of an oxidizing enzyme, such as horseradish peroxidase. The present invention is further directed to a two-pack coating composition which includes a polymeric component and a catalytic component, which are mixed together prior to use.
