Screed die ir absorbtion coating

Abstract

The striper 10 has an aluminum die trough 12 and doctor gate 14 components having a black anodized Type 2 Class 2 coating. Other components 16 of the screed box 18 which are not intended to transfer hear are coated with a reflective E-nickel. These components 16 are more likely to be use to lift the screed box and will absorb less heat due to their reflective properties.

1 . In a thermoplastic line striper having non-heated material containing components and a screed box with walls, an aluminum die trough and a doctor gate, the improvement comprising coating said walls, said die trough and said doctor gate with a heat absorbing coating. 
     
     
         2 . The line striper of  claim 1  wherein said coating is a black anodized Type 2 Class 2 coating. 
     
     
         3 . The line striper of  claim 1  wherein said non-heated material containing components are coated with a reflective material. 
     
     
         4 . The line striper of  claim 3  wherein said reflective material coating is E-nickel.
