Title: HARD SURFACE TREATMENT COMPOSITION
Abstract:
The present invention is in the field of hard surface treatment compositions. The invention particularly relates to hard surface treatment compositions that render a substrate hydrophobic and also repellent to aqueous stains and soils. It is an object of the present invention to provide a composition that is transparent, metal free, and upon use, renders a surface hydrophobic and repellant to stains and soils. It has been found that hydrophobicity and aqueous stain and soil repellence can be imparted to a surface by the deposition of polystyrene or a polystyrene copolymer onto the said surface.
