Abstract
The present invention relates to a fire protection coating composition and method of using same on substrate materials for which some degree of fire protection from intense heating and fire is necessary or desirable. The fire protection coating composition will expand upon being exposed to fire or intense heating to provide a protective layer for the substrate material for which protection is required.
