Transparent glazing and use thereof in a chilling chamber door comprising in particular a glazing under vacuum

Abstract

The subject of the invention is a transparent glazing unit having at least one viewing area and its use in a door of a refrigerated enclosure and more particularly a glazed door, the glazed area of which essentially consists of a vacuum glazing unit. According to the invention the viewing area is combined with an antifrosting absorbent layer deposited on at least one surface of the said area.

1 - 14 . (Canceled).  
     
     
         15 . A method of manufacturing a refrigerator door having a transparent substrate, comprising: 
 mixing an isocyanate with a polyol to form a mixture;    applying the mixture to at least a portion of the substrate; and    curing the substrate,    wherein the substrate is part of a refrigerator door or is used to manufacture a refrigerator door.    
     
     
         16 . The method of  claim 15 , wherein the substrate is part of a refrigerator door.  
     
     
         17 . The method of  claim 15 , wherein no water condenses on the portion of the substrate to which the mixture has been applied when said portion is maintained at a temperature of −28° C. and exposed to an atmosphere at a temperature of 25° C. for 12 seconds.  
     
     
         18 . The method of  claim 15 , wherein no water condenses on the portion of the substrate to which the mixture has been applied when said portion is maintained at a temperature of −28° C. and exposed to an atmosphere at a temperature of 25° C. for 3 minutes.  
     
     
         19 . A method of manufacturing a refrigerator door having a transparent substrate, comprising depositing a polyurethane directly on at least a portion of the substrate, 
 wherein the substrate is part of a refrigerator door or is used to manufacture a refrigerator door.    
     
     
         20 . The method of  claim 19 , wherein the substrate is part of a refrigerator door.  
     
     
         21 . The method of  claim 19 , wherein no water condenses on the portion of the substrate to which the mixture has been applied when said portion is maintained at a temperature of −28° C. and exposed to an atmosphere at a temperature of 25° C. for 12 seconds.  
     
     
         22 . The method of  claim 19 , wherein no water condenses on the portion of the substrate to which the mixture has been applied when said portion is maintained at a temperature of −28° C. and exposed to an atmosphere at a temperature of 25° C. for 3 minutes.
