Abstract
A method of crosslinking an oxidative polymer having oxidatively crosslinkable functional groups and a two-pack composition used therein. 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.
Claims10
A two-pack coating composition comprising:
- a first container containing a polymeric component, which comprises an oxidative polymer having oxidatively crosslinkable functional groups and wherein said oxidative polymer comprises as polymerized units at least one ethylenically unsaturated monomer;
- and
- a second container containing a catalytic component, which comprises a catalytic amount of an oxidizing enzyme sufficient to crosslink said oxidatively crosslinkable functional groups on said oxidative polymer, when said polymeric component is mixed with said catalytic component.
