Coating with metal marking resistance

Abstract

A coating composition having excellent durability and resistance to metal marking. The coating composition includes a binder system comprising at least a first resin component, optionally, one or more other resin components, a crosslinking component and a texture-producing component. Coated articles with the coating composition applied to at least a portion of a surface thereof are also provided.

1 . A coated article comprising
 a substrate; and   a cured coating disposed on the substrate, wherein the cured coating is derived from a coating composition comprising:   a binder resin system comprising at least a first resin component;   a crosslinking component; and   a texture-producing component,   
       wherein the cured coating demonstrates resistance to metal marking. 
     
     
         2 . (canceled) 
     
     
         3 . The article of  claim 1 , wherein the first resin component is a polyester resin. 
     
     
         4 . The article of  claim 1 , wherein the binder resin component further includes a second resin component comprising a silicon-modified polyester resin. 
     
     
         5 . The article of  claim 1 , wherein the crosslinking component is a hydroxyl-reactive crosslinker. 
     
     
         6 . The article of  claim 1 , wherein the crosslinking component is an amine-functional crosslinker. 
     
     
         7 . The article of  claim 1 , wherein the crosslinking component is selected from an aminoplast, an amino- or amido-group carrying substance, a blocked isocyanate, or a combination thereof. 
     
     
         8 . The article of  claim 1 , wherein the texture-producing component is an amine of the general formula NR 1 R 2 R 3 , wherein
 R1, R2 and R3 are each independently H, C1-C10 alkyl, branched C4-C10 alkyl, hydroxyl-substituted C1-C10 alkyl, hydroxyl-substituted branched C4-C10 alkyl, phenyl, or substituted phenyl.   
     
     
         9 . The article of  claim 1 , wherein the article is selected from metal structures, metal building products, household appliances, and combinations thereof. 
     
     
         10 . The article of  claim 1 , wherein the coating composition is applied to the substrate at a film thickness of about 0.5 to 2 mil. 
     
     
         11 . (canceled) 
     
     
         12 . The article of  claim 1 , wherein the cured coating formed from the composition has 60° gloss of about 5. 
     
     
         13 . The article of  claim 1 , wherein the cured coating formed from the composition has 60° gloss of less than about 5. 
     
     
         14 . The article of  claim 1 , wherein the texture-producing component is present in an amount of about 0.001 to 5 weight percent, based on the total weight of the coating composition. 
     
     
         15 . The article of  claim 1 , wherein the coating composition includes up to about 5 wt % flatting agent. 
     
     
         16 . The article of  claim 1 , wherein the binder resin component is present in an amount of about 1 to 65 weight percent, based on the total weight of the composition.
