Patent ID: 8679825

Claim:
A method for facilitating removal of a bioorganic stain from a surface comprising: providing a curable polymeric coating comprising a polymer resin, a surfactant, a non-aqueous organic solvent having a log P in the range of −0.5-2, inclusive, where log P is the base ten logarithm of the ratio of solubility of the non-aqueous organic solvent in n-octanol to solubility of the non-aqueous organic solvent in water, and a cross-linker; dispersing an amylase or analogue thereof having amylase activity within said curable polymeric coating; curing said curable polymeric coating such that said amylase or analogue thereof having amylase activity is capable of enzymatically cleaving a component of said bioorganic stain when contacting said curable polymeric coating; and contacting said curable polymeric coating with said bioorganic stain.
