MULTILAYERED COATING FILM AND COATED ARTICLE
A metallic base coating film 15 is stacked on a colored base coating film 14 provided on a surface of an article to be coated. While the colored base coating film 14 alone is formed on the surface of the article to be coated, a light reflectance at light receiving angles of 15? and 45? is measured to be 2% or below in a wavelength ranging from 450 nm to 700 nm inclusive. On the metallic base coating film 15 alone, the light reflectance measured at the light receiving angle of 15? ranges from 20% to 50% inclusive in the wavelength ranging from 450 nm to 700 nm inclusive, and the light reflectance measured at the light receiving angle of 45? is 2.5% or below in the wavelength ranging from 450 nm to 700 nm inclusive.
DIGITAL EMBOSSING
A method of forming a digital embossing on a surface by bonding hard press particles to a carrier. A liquid binder pattern is applied on the carrier by a digital drop application head. Hard press particles are applied on the carrier and the binder pattern such that some hard press particles are bonded to the carrier by the liquid pattern and non-bonded press particles are removed. The carrier with the bonded hard press particles is pressed to the surface and an embossing is formed when the carrier with the hard press particles is removed.
Curable film-forming compositions demonstrating burnish resistance and low gloss, and methods of improving burnish resistance of a substrate
The present invention is directed to curable film-forming compositions comprising: (a) a polymeric binder comprising: (i) a polysiloxane having reactive functional groups and in which is dispersed protonated silica particles having an average particle size of 2 to 20 microns; and (ii) optionally, at least one additional polymeric resin different from the polysiloxane (i), having reactive functional groups; and (b) a curing agent containing functional groups that are reactive with the reactive functional groups of (i) and/or (ii). After application to a substrate as a coating and after curing, the curable film-forming composition demonstrates an initial 85 gloss of less than 30 and an increase in 85 gloss of no more than 10 gloss units when subjected to various ABRASION TEST METHODS as defined herein. Also provided is a method of improving burnish resistance of a substrate using the curable film-forming compositions of the present invention.
Powder Coating Compositions Capable of Having a Substantially Non-Zinc Containing Primer
Corrosion and chip-resistant coatings for high tensile steel components, such as automotive coil springs, can be formed from a coating composition comprising a primer having an epoxy resin with the proviso that the epoxy resin does not have an EEW of about 860 to about 930, a polyhydroxyl functional phenolic curing agent having a HEW of about 200 to about 500, and a platy filler. The primer contains less than 20 wt % zinc. The topcoat includes an epoxy resin having an epoxy equivalent weight of about 450 to about 1400, an elastomer-modified epoxy resin having an epoxy equivalent weight of about 1000 to about 1600, a foaming agent and a reinforcing fiber.
DIRECT-TO-METAL COATING COMPOSITION
A fast drying, heavy metal-free, high performance coating composition with outstanding UV resistance, and excellent corrosion resistance coupled with fast dry and long pot life. This coating can be applied over DTM, such as blasted cold rolled steel, or treated cold rolled steel, aluminum and treated aluminum. High corrosion resistance without sacrificing gloss or UV resistance achieved by selecting proper pigments and proper pigment design and packing by advantageously utilizing differing pigment morphologies (sizes and shape).
Anti-slip coating and preparation, application method thereof
The present invention relates to anti-slip coatings comprising resin, diluent, PMU particles and photo-initiator. The present invention also relates to the preparation of anti-slip coatings, methods for applying anti-slip coatings, and substrates coated with such anti-slip coatings.
Sinterable metal paste for use in additive manufacturing
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.
