Patent ID: 11535758

Abstract:
Thermosetting powder coating compositions and processes for making the thermosetting powder coating compositions and processes for coating an article with the thermosetting powder coating compositions are disclosed. Cured thermosetting powder coating compositions are obtained by curing of the thermosetting powder coating compositions of the invention. Articles are provided having coated thereon the thermosetting powder coating compositions as well as to articles having coated and cured thereon the thermosetting powder coating compositions. The thermosetting powder coating compositions exhibit a substantially lower Tchalk-free, that is a ΔTchalk-free which is in the range of from and including 5 up to and not including 10° C., wherein ΔTchalk-free=Tchalk-freeREF−Tchalk-freeA where Tchalk-freeA is the Tchalk-free of a thermosetting powder coating composition according to the invention (TPCC-A) and Tchalk-freeREF is the Tchalk-free of a thermosetting powder coating composition not according to the invention (TPCC-REF) that is comparable to TPCC-A.
