The method includes heating, at 30 to 300 C., a powder-form mixture which is composed of zinc oxide, cyanuric acid, and water, which has a ratio by mole of zinc oxide to cyanuric acid of 2 to 3, and which has a water content of 9 to 18 mass %, in a closed or unclosed state.

A method of forming a digital print on a surface (2) by applying powder of dry ink (15) including colorants (7) on the surface, bonding a part of the dry ink (15) powder to the surface (2) by a digital heating print head (80) such that the digital print is formed by the bonded dry ink colorants (7) and removing non-bonded dry ink (15) from the surface (2).

A water-based solvent-free and IR reflecting surface treatment composition is disclosed. In one or more embodiments, the composition includes: (1) a base comprising (a) 30 to 60% by weight of an acrylic resin; (b) 1 to 10% by weight of an alkyd resin; (c) 0.1 to 2% by weight of a polyolefin; (d) 0.1 to 1% by weight of an ammonium salt; (e) less than 0.1% by weight of a preservative; (f) water such that base reaches 100 % by weight; and (2) a paste comprising (i) metal oxides having a mean particle size between 0.05 and 5 m; and (ii) a polymeric binder.

A coating composition having excellent damage tolerance. The coating composition includes a binder system comprising at least a fluoropolymer, optionally, one or more other resin components, a crosslinking component and at least one inorganic filler and organic filler. Coated articles with the coating composition applied to at least a portion of a surface thereof are also provide.

The present invention relates to a coating composition comprising an aqueous dispersion of a binder and first and second core-shell polymer particles having aqueous neutralized acid cores, wherein the dry bulk density of the first core-shell polymer particles is in the range of 0.25 to 0.5 g/mL; and the dry bulk density of the second core-shell polymer particles is in the range of 0.30 to 0.90 g/mL. The composition of the present invention is useful as an undercoat layer for a thermosensitive recording material.

A material and method are disclosed such that the material can be used to form functional metal pieces by producing an easily sintered layered body of dried metal paste. On a microstructural level, when dried, the metal paste creates a matrix of porous metal scaffold particles with infiltrant metal particles, which are positioned interstitially in the porous scaffold's interstitial voids. For this material to realize mechanical and processing benefits, the infiltrant particles are chosen such that they pack in the porous scaffold piece in a manner which does not significantly degrade the packing of the scaffold particles and so that they can also infiltrate the porous scaffold on heating. The method of using this paste provides a technique with high rate and resolution of metal part production due to a hybrid deposition/removal process.

Kaolin compositions comprising coarse kaolin particles are disclosed herein. The kaolin compositions can include kaolin particles having a GE brightness of at least 78 and a particle size distribution wherein at least 50% by weight of the kaolin particles have an equivalent size diameter (e.s.d.) of 30 m or greater. In some embodiments, the kaolin compositions can include kaolin particles having a bimodal particle distribution. In other embodiments, the kaolin compositions can include kaolin particles having a low crystalline silica content, such as a crystalline silica content of 0.1% by weight or less and a particle size distribution wherein at least 50% by weight of the kaolin particles have an equivalent size diameter (e.s.d.) of 15 m or greater. In some embodiments, the kaolin particles can be free of crystalline silica. Methods of making and using the kaolin compositions are also disclosed herein.
