Abstract

An automotive refinish coating mixer system includes (a) one or both of (i) at least one pellet of a compressed mixture of metal pigment and a powdered, water-soluble polymer and (ii) at least one pre-measured portion of metal flake pigment sealed in water-soluble polymer film; (b) a plurality of aqueous pigmented and unpigmented bases; and (c) a reducer base.

1 . An automotive refinish coating mixer system, comprising:
 (a) at least one of
 a pellet, the pellet comprising a compressed mixture of a metal pigment and a powdered, water-soluble polymer, and 
 (ii) a pre-measured portion of a metal pigment sealed in a water-soluble polymer film; 
   (b) a plurality of aqueous pigmented and unpigmented bases; and   (c) a reducer base.   
     
     
         2 . The automotive refinish coating mixer system according to  claim 1 , wherein the pellet (i) is present and wherein the metal pigment comprises an aluminum pigment. 
     
     
         3 . The automotive refinish coating mixer system according to  claim 2 , wherein the water-soluble polymer of the pellet (i) comprises polyvinylpyrrolidone. 
     
     
         4 . The automotive refinish coating mixer system according to  claim 2 , wherein the pellet (i) comprises a water soluble coating. 
     
     
         5 . The automotive refinish coating mixer system according to  claim 1 , wherein the pre-measured portion (ii) is present and wherein the metal pigment comprises an aluminum pigment. 
     
     
         6 . The automotive refinish coating mixer system according to  claim 5 , wherein the water-soluble polymer of the pre-measured portion (ii) comprises polyvinyl alcohol. 
     
     
         7 . The automotive refinish coating mixer system according to  claim 1 , wherein the metal pigment comprises a surface treatment that resists degradation by water. 
     
     
         8 . A pellet comprising:
 a compressed mixture of a metal pigment, and   a powdered, water-soluble polymer.   
     
     
         9 . The pellet according to  claim 8 , wherein the metal pigment comprises an aluminum pigment. 
     
     
         10 . The pellet according to  claim 8 , wherein the water-soluble polymer comprises polyvinylpyrrolidone. 
     
     
         11 . The pellet according to  claim 8 , wherein the metal pigment comprises a surface treatment that resists degradation by water. 
     
     
         12 . The pellet according to  claim 8 , wherein the pellet further comprises a water-soluble coating. 
     
     
         13 . A pre-measured portion of a metal pigment sealed in a water-soluble polymer film. 
     
     
         14 . The pre-measured portion according to  claim 13 , wherein the metal pigment comprises an aluminum pigment. 
     
     
         15 . The pre-measured portion according to  claim 13 , wherein the water-soluble polymer comprises polyvinyl alcohol. 
     
     
         16 . The pre-measured portion according to  claim 13 , wherein the metal pigment comprises a surface treatment that resists degradation by water. 
     
     
         17 . A method of making a coating composition, the method comprising at least one selected from the group consisting of:
 incorporating the pellet according to  claim 8 , and   incorporating a pre-measured portion of a metal pigment sealed in a water-soluble polymer film.   
     
     
         18 . A method of making a coating composition, the method comprising at least one selected from the group consisting of:
 incorporating a pellet comprising a mixture of a metal pigment and a powdered water-soluble polymer, and   incorporating the pre-measured portion according to  claim 13 .
