An article with an abradable dry powder coating thereon comprises an
abradably coated article with a substrate surface and having at least one
coating of a liquid primer on the substrate surface and then coating with
at least one abradable dry powder coating on the surface of the liquid
primer. The sequence of layers may also be reversed, or additional layers
may be useful. The abradable dry powder coating is formed of a dry powder
coating composition including a thermoset resin having a cure temperature
combined with at least one filler material, wherein the filler is formed
of a material which does not melt substantially at or below the cure
temperature of the resin, whereby an abradable coating results employing
a filler to make the coating. A method of making a composition for
coating an article with a coating curable into an abradable coating is
also disclosed, comprising melt-mixing an evaporative carrier-free
mixture of a dry powder thermoset resin having a cure temperature, to
form a mass composite, wherein the filler is formed of a material which
does not substantially melt at or below the cure temperature of the
resin, cooling the mass composite, and breaking the cooled mass composite
into powder particles, thereby forming the composite powder composition.
