Abstract
A process of stabilizing the activity of an enzyme against inactivation by water weathering are provided including associating one or more polymeric moieties of a polyoxyethylene having a molecular weight of 10,000 Daltons or greater with an enzyme to form a chemically modified enzyme; and dispersing said chemically modified enzyme in a base to form a water-stabilized active coating material.
Claims8
A process of stabilizing the activity of an enzyme against water weathering in a coating composition comprising:
- associating one or more polymeric moieties of a polyoxyethylene having a molecular weight of 10,000 Daltons or greater with an enzyme to form a chemically modified enzyme;
- and
- dispersing said chemically modified enzyme in a base to form a water-stabilized active coating material.
