Lubricant aerosol dispensing container

Abstract

An aerosol dispensing container or pressurized vessel such as a metallic spray can at least contains a non-flammable aerosol propellant and a polytetrafluoroethylene (PTFE) lubricant mixture (propellant/lubricant mixture). The propellant/lubricant mixture has been formulated such that is non-migrating, i.e., stays where it is applied rather than spreading into surrounding areas. The propellant/lubricant mixture has a wide range of applications and is especially well formulated for automotive applications for which smooth, repeated movement is essential. The low coefficient of friction characteristic of the propellant/lubricant mixture translates to superior effectiveness. By providing this propellant/lubricant mixture in the pressurized vessel, the PTFE lubricant of the present invention can be applied in places that conventional liquid lubricants could not reach. For example in small spaces between plastic, rubber, or metal parts that cause unwanted squeaking, rattling or other noise.

1 . A lubricant aerosol dispensing container comprising: 
 a pressurized vessel having a spray outlet;    a non-flammable aerosol propellant contained in the vessel; and    a lubricant contained in the vessel, the lubricant being composed of dihydrodecafluoropentane 138495-428, polytetrafluoroethylene 9002-84-0, perfluoroalkylether 60614-51-4, and tetrafluoroethane 811-97-2,    the propellant being formulated with retention properties to propel the lubricant and retain the lubricant on a surface where the lubricant is sprayed.    
   
   
       2 . The lubricant aerosol dispensing container according to  claim 1 , wherein 
 the pressurized vessel is a metallic can.    
   
   
       3 . A method of coating a surface with a thin film comprising: 
 providing a pressurized vessel having a spray outlet;    providing a non-flammable aerosol propellant in the vessel;    providing a lubricant in the vessel, with the lubricant being composed of dihydrodecafluoropentane 138495-428, polytetrafluoroethylene 9002-84-0, perfluoroalkylether 60614-51-4, and tetrafluoroethane 811-97-2;    mixing the aerosol propellant and the lubricant as a mixture in the container; and    applying the mixture to the surface to leave a lubricating film as the thin film on the surface.    
   
   
       4 . The method according to  claim 3 , wherein 
 the pressurized vessel is a metallic can.    
   
   
       5 . The method according to  claim 4 , wherein 
 the applying of the mixture includes forming lubricating film on an automobile part that includes the surface.    
   
   
       6 . The method according to  claim 3 , wherein 
 the applying of the mixture includes forming lubricating film on an automobile part that includes the surface.
