Method and sealant for sealing air filter leaks

Abstract

The present invention relates generally to a method and device for composition air filter leaks, and, more particularly, to a method and sealant for sealing high efficiency air filter leaks without blocking significant parts of the filter.

1 . A sealant comprising a mixture of:
 a. a micro fiber glass; and   b. a polymeric binder, wherein said mixture is pressurized with a propellant within a housing.   
     
     
         2 . The sealant of  claim 1 , wherein said mixture further comprises a solvent. 
     
     
         3 . The sealant of  claim 2 , wherein said solvent is selected from the group consisting of water, weak acid alcohol, and a mineral spirit. 
     
     
         4 . The sealant of  claim 2 , wherein said micro fiber glass comprises borosilicate fibers. 
     
     
         5 . The sealant of  claim 4 , wherein said polymeric binder is selected from the group consisting of acrylic ester latex, urethane, silicone, and a moisture cure adhesive. 
     
     
         6 . The sealant of  claim 5 , wherein said propellant is a compressed gas selected from the group consisting of nitrogen, air, or other non highly flammable gas. 
     
     
         7 . The sealant of  claim 6 , wherein said mixture comprises less than 10% micro fiber glass. 
     
     
         8 . The sealant of  claim 7 , wherein said mixture comprises up to 50% polymeric binder. 
     
     
         9 . The sealant of  claim 8 , wherein said housing is an aerosol can. 
     
     
         10 . A method of sealing a leak in a portion of an air filter comprising the steps of:
 a. applying a sealant comprising a mixture of a micro fiber glass and a polymeric binder, wherein said mixture is pressurized with a propellant within a housing, to the portion of the air filter which includes the leak; and   b. allowing said sealant to cure.   
     
     
         11 . The sealant of  claim 10 , wherein said mixture further comprises a solvent. 
     
     
         12 . The method of  claim 11 , wherein said housing is an aerosol can. 
     
     
         13 . The method of  claim 12 , wherein the step of applying further comprises the step of spraying said sealant from said aerosol can on the portion of the air filter which includes the leak. 
     
     
         14 . The method of  claim 13 , wherein the step of allowing further comprises the step of applying heat to said sealant. 
     
     
         15 . A method of sealing a leak in a portion of an air filter comprising the steps of:
 a. applying a first mixture comprising a micro fiber glass and a solvent, wherein said mixture is pressurized with a propellant within a first housing, to the portion of the air filter which includes the leak;   b. applying a second mixture comprising a polymeric binder and a solvent, wherein said mixture is pressurized with a propellant within a second housing, to the portion of the air filter which includes the leak; and   c. allowing the first mixture and second mixture combination to cure.   
     
     
         16 . The method of  claim 15 , wherein said first housing and said second housing each comprise an aerosol can. 
     
     
         17 . The method of  claim 16 , wherein the step of allowing further comprises the step of applying heat to said sealant.
