Disclosed is an anti-fog or anti-frost coating comprising a mixture of: i) a first component comprising about 46% diacetone alcohol, about 4% N-methyl Pyrrolidone, about 4% t-butanol, about 8% Cyclohexane, about 6% 2,4-pentanedione, and about 2% naptha; and ii) a second component comprising about 66% polyisocyanate, about 1% free monomeric isocyanates, about 11% xylene, about 11% n-butyl acetate, and about 11% toluene; wherein the mixture ratio of the first component to the second component is about 100:about 30-33 and wherein the mixture comprises a silane. Also disclosed is a refrigeration door having an outer surface and adapted to be mounted on a refrigerating compartment, said door comprising: a first sheet of glass; a second sheet of glass; a first sealant assembly disposed around the periphery of said first sheet of glass and said second sheet of glass for maintaining said first sheet and said second sheet in spaced apart relationship from each other; a first low emissivity coating adjacent a surface of said first sheet or said second sheet of glass; an anti-fog or anti-frost coating adjacent a surface of at least one of said sheets of glass; said first sheet and second sheets of glass, said first sealant assembly, and said first low emissivity coating forming an insulating glass unit having a U value substantially equal to or less than 0.2 BTU/hr-sq fr-F or an emissivity substantially equal to or less than 0.04; and a frame secured around the periphery of said insulating glass unit wherein the anti-fog or anti-frost coating comprises a first silane.
