A decorative panel includes a substrate and a wear layer. The wear layer has a varnish coat that includes hard particles over its entire thickness. The hard particles have an S50 particle size determined from the cumulative particle size distribution according to volume measured by laser diffraction as the particle size at which 50% of the hard particles are smaller than this particle size S50. The varnish coat has a thickness T that is between 0.5*S50 and 2*S50.

A waterborne coating composition including a film-forming binder, a water-based carrier liquid, monosize polymeric particles having a coefficient of variation (CV) of about 50 percent or less and a Shore D hardness of at least about 75 as measured by ASTM D2240-15; and a polysiloxane dispersible in water, which provides improved scuff and mar resistance in architectural coating compositions.

Improved silica-based matting agents are disclosed. The matting agents are useful in waterborne coatings composition to provide exceptional properties to a wood based substrate. Films resulting from the silica-based matting agents on a wood substrate unexpectedly provide improved chemical resistance and/or film clarity to the surface of the wood substrate. Methods of making and using the matting agents are also disclosed.

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.

The present disclosure provides a coating film and a display panel, wherein the coating film includes a tetrafunctional polyurethane acrylate oligomer having a structure as shown below. The coating film according to the present disclosure can enhance the adhesion force to a polymethyl methacrylate film.

A rolling bearing includes an outer ring having an outer surface configured to be fitted into a first component, an inner ring having an inner surface configured to be fitted onto a second component, at least one rolling element arranged between the outer ring and the inner ring, and an antimony-free composite coating on the outer surface of the outer ring and/or the inner surface of the inner ring. The antimony-free composite comprises a binder and polytetrafluorethylene as a solid lubricant.

The present invention relates to aluminum flakes having a thickness between 7 and 9 nm, coating compositions containing them and the use of the coating compositions for forming (security) products. When the compositions of the present invention are used in coating a hologram the obtained products show an extremely bright OVD image and extremely strong rainbow effect, high purity and contrast.

Sag control compositions, methods of forming sag control compositions, and methods of forming coating systems that include at least one coating layer including urea crystals of such sag control compositions are provided herein. In an embodiment, a sag control composition includes urea crystals and a non-polymeric organic solvent. The urea crystals include the reaction product of a polyisocyanate and a mono-amine. The sag control composition is a stable mixture with a single phase at a temperature of about 21 C. based upon visual observation for a period of at least 10 minutes after forming the mixture.

A feedstock for a cold spray process includes a plurality of globule bodies. The globule bodies include a plurality of discrete particles bonded to one another to define porous globule bodies. The bonds between the particles are of sufficient strength such that the globule bodies can retain both the body integrity as well as the body shape when the body experiences acceleration from a conveying gas in a cold spray technique. Methods of making the feedstock and globule bodies are also described.

A method, a panel and equipment to form a digital print by applying dry ink (15), preferably including particles of pigment coated wood fibres (61), on a surface (2), bonding a part of the particles with a liquid blank ink drops (57) and removing the non-bonded particles from the surface (2).
