There are very few violet or pink colored commercial pigments that display high heat stability, resistance to acidic conditions, or good lightfastness. This technology results in pigments that fall into the above color space, but display improved chemical and weathering stability. The pigments based of this technology have the molar ratio (A2O)x(BO)y(C2O5)z(DO3)w(EO2)v, where 2x+y+2z+w+v≅100. Where A is Li or Li with one or more of Cu, Na, or K, where B is Co or Co with one or more of Ca, Cu, Fe, Mg, Mn, Ni, Sn, or Zn, where C is Nb, Sb, or combination thereof, where D is Mo, W or combination thereof, where E is Sn, Ti, Zr, or combination thereof. The above formulation may be modified with a dopant addition of Al, B, Ba, Bi, Ca, Ce, Cr, La, P, Pr, Si, Sr, Ta, V, or Y where the dopant concentration represents 5 atomic % or less of the total number of moles of components A+B+C+D+E.

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.
摘要:
A coated article is described, including a substrate with a coating composition applied thereon to provide a coated article with a textured surface. In one aspect, the coated article is a steel rebar used to reinforce concrete. The textured surface provides optimal surface roughness and demonstrates superior pullout strength relative to an uncoated standard.
摘要:
A treatment method includes the steps of: Providing an initial supply of an ammonium octamolybdate precursor powder having a bi-modal particle size distribution; applying a quantity of solvent to the initial supply of ammonium octamolybdate precursor powder to form a moistened intermediate powder; and allowing the moistened intermediate powder to adsorb the applied solvent over a time period, the quantity of solvent applied and the time period being sufficient to form a treated ammonium octamolybdate powder composition having a substantially uni-modal particle size distribution.

摘要:
An object of the present invention is to provide a particulate composite which is free from fluorosurfactants having a high environmental impact, and can form a coating film that has excellent adhesion to a substrate and is uniformly adhered to the substrate even if containing a small amount of an adhesive component. The particulate composite of the present invention contains: a fluoropolymer; an adhesive polymer; and less than 0.1 ppm of a fluorosurfactant.
