Powder-coating compositions containing transfer efficiency-enhancing additives

摘要

This invention relates to a powder coating composition made from at least two components comprising (A) a film forming resin composition; and (B) a transfer efficiency enhancing amount of at least one aromatic ring compound containing at least two substituents, wherein one of the two substituents is selected independently from the group consisting of (i) groups containing at least one carboxy or a carboxy producing moiety; (ii) alkoxy groups; and (iii) halogen groups; and the second substitutent is a nitro or a halogen group; wherein component (B) is incorporated into the powder coating composition by addition of component (B) to an extruded composition comprising components other than component (B) The invention also relates to a method for coating a substrate using the foregoing powder coating composition.
