Biocidal Coatings
Biocidal coatings can be formed from aqueous solution which dries to a clear hard film on which micro organisms will not grow. The solution may be applied by wiping, brushing spraying, dipping onto an inanimate surface and drying or allowing drying. Compositions according to the invention may be formed into films for example on door handles, tap handles, toilet seats, telephone handsets, air conditioning ducts, bench tops, or the like.
