Abstract:
A differential adhesion window coating composition applied to the non-glass and the glass materials of a window, wherein the differential adhesion window coating composition comprises:a resin emulsion and an amount of compatible water soluble hygroscopic agent which will remain in the differential adhesion window coating in sufficient quantity after drying so that cohesive forces of said differential adhesion window coating are greater than adhesive forces between said differential adhesion window coating and said glass material of the window thereby making said differential adhesion window coating removable by lifting from said glass material of the window; andso that cohesive forces of said differential adhesion coating are less than adhesive forces between said differential adhesion window coating and said non-glass material of the window thereby making said differential adhesion window coating a permanent coating on the non-glass material of the window, said water soluble hygroscopic agent being glycerol and said differential adhesion window coating composition being devoid of pigment.
