<p>A paint formulation which contains specific enzymes which remain inactive in an applied surface coating of the paint formulation until specifically activated by a subsequently-applied applicator solution to facilitate removal of the surface coating. When the applicator is applied to the surface coating, the enzymes catalyse the hydrolysis of the binder in the paint or surface coating, e.g. by cleaving the ester bonds in the 1 and 3 positions of the triglyceride molecules. This allows for easy and rapid removal of the coating without damaging or affecting the underlying surface. The invention is useful either for general purpose paint removal, or for the cleaning up or removal of unwanted graffiti.</p> |
