    摘要: The invention relates to a thermosetting powder coating composition C (PCC C) comprising a physical mixture of a thermosetting powder coating composition A (PCC A) with a separate, distinct thermosetting powder coating composition B (PCC B). The invention further relates to a process for making said thermosetting powder coating composition C and processes for coating an article with said thermosetting powder coating composition C. The invention further relates to a cured thermosetting powder coating composition C (c-PCC C). The invention further relates to an article having coated thereon said thermosetting powder coating composition C as well as to an article having coated and cured thereon said thermosetting powder coating composition C. The invention further relates to the use of PCC C for heat-curing at low temperatures. The invention relates also to a use of PCC C for making a cured PCC C, preferably said cured PCC C is a powder coating having one or multiple of properties such as excellent resistance to swelling, good smoothness, good chemical resistance, low gloss, low yellowness, in any combination. The invention further relates to the use of said thermosetting powder coating composition C, to the use of an article having coated thereon said thermosetting powder coating composition C and to the use of an article having coated and cured thereon said thermosetting powder coating composition C.

    摘要: An abradable dry powder coating (22) composition for coating onto a surface (12) for subsequent curing to form into an abradable coating, including a powder (16) formed of uncured thermoset resin with at least 15 volume percent filler, wherein the filler does not substantially melt below the cure temperature of the resin. Method for making the coating composition includes melt-mixing the thermoset resin with at least 15 volume percent of filler, cooling the resulting mass composite, and then breaking the cooled mass composite into powder particles (16). Method of coating an article with an abradable coating includes applying the dry composite powder with the filler therein onto a substrate and curing the dry powder composition, preferably by electrostatic coating. An article is also disclosed which is coated with the abradable coating.
