Aerosol Systems and Methods for Dispensing Texture Material

Abstract

Texture material for applying a repair coat to a substrate substantially comprising a base portion, a particulate portion, and a propellant portion. The particulate portion is made of at least one of urethane foam and melamine foam. When the texture material is contained within a sealed chamber, the propellant portion exists in a gas state and a liquid state, the propellant portion in the gas state pressurizes the base portion, the particulate portion, and the propellant portion in the liquid state and the at least one of urethane foam and melamine foam exists in solid particulate form.

What is claimed is: 
     
         1 . Texture material for applying a repair coat to a substrate substantially comprising:
 a base portion;   a particulate portion made of at least one of urethane foam and melamine foam; and   a propellant portion; whereby   when the texture material is contained within a sealed chamber,
 the propellant portion exists in a gas state and a liquid state; 
 the propellant portion in the gas state pressurizes the base portion, the particulate portion, and the propellant portion in the liquid state; and 
 the at least one of urethane foam and melamine foam exists in solid particulate form. 
   
     
     
         2 . Texture material as recited in  claim 1 , in which the propellant portion comprises a hydrocarbon propellant. 
     
     
         3 . Aerosol material as recited in  claim 1 , in which the propellant portion comprises DME. 
     
     
         4 . Aerosol material as recited in  claim 1 , in which the propellant portion comprises A-40. 
     
     
         5 . Aerosol material as recited in  claim 1 , in which the propellant portion comprises A-70. 
     
     
         6 . A method of forming texture material comprising the steps of:
 providing a base portion;   providing a particulate portion made of at least one of urethane foam and melamine foam;   providing a propellant portion;   combining the base portion, the particulate portion, and the propellant portion to form the texture material such that, when arranged in a sealed chamber,
 the propellant portion exists in a gas state and a liquid state; 
 the propellant portion in the gas state pressurizes the base portion, the particulate portion, and the propellant portion in the liquid state; and 
 the-at least one of urethane foam and melamine foam exists in solid particulate form. 
   
     
     
         7 . A method as recited in  claim 6 , in which the propellant portion comprises a hydrocarbon propellant. 
     
     
         8 . A method as recited in  claim 6 , in which the propellant portion comprises DME. 
     
     
         9 . A method as recited in  claim 6 , in which the propellant portion comprises A-40. 
     
     
         10 . A method as recited in  claim 6 , in which the propellant portion comprises A-70. 
     
     
         11 . Texture material to be dispensed from a structure, comprising:
 a base portion;   a particulate portion made of at least one of urethane foam and melamine foam; and   a propellant portion; whereby   when the texture material is confined within the structure,
 the propellant portion exists in a gas state and a liquid state, 
 the base portion, the particulate portion, and the propellant portion in the liquid state form a liquid mixture, and 
 the propellant portion in the gas state pressurizes liquid mixture; and 
   when the texture material is not confined within the structure, the propellant portion in the gas state gas state displaces at least part of the liquid mixture out of the structure and onto the uncoated portion of the substrate to form the repair coat such that the repair coat substantially matches the coated portion of the substrate.   
     
     
         12 . Texture material as recited in  claim 11 , in which the propellant portion comprises a hydrocarbon propellant. 
     
     
         13 . Texture material as recited in  claim 11 , in which the propellant portion comprises DME. 
     
     
         14 . Texture material as recited in  claim 11 , in which the propellant portion comprises A-40. 
     
     
         15 . Texture material as recited in  claim 11 , in which the propellant portion comprises A-70.
