The purpose of the present invention is the use of (Bi.sub.1-xA.sub.x)(V.sub.1-yM.sub.y)0.sub.4 in a non-stick coating for a household article so as to reduce or prevent the color change of said coating during the manufacturing process thereof, characterised in that: —x is equal to 0 or x is from 0.001 to 0.999; —y is equal to 0 or y is from 0.001 to 0.999; —A and Mare selected from the group consisting of nitrogen, phosphorus, an alkali metal, an alkaline earth metal, a transition metal, a poor metal, a metalloid or a lanthanide; —A and M are different from each other.

The invention provides methods and compositions related to adding a coating to a metal surface under low temperature conditions, such as a patina, where a binder is added to the surface, followed by a first dye, optionally the integrity of the first dye layer is disrupted to provide a mottled, cracked appearance, then a second dye layer is added, followed by a clear protective coat.

Acid-catalyzed curable coating compositions containing 1,1-di-activated vinyl compounds are described, including multi-layer coatings. Also provided are processes for coating substrates with coating compositions comprising 1,1-di-activated vinyl N compounds. Also provided are coated articles comprising coatings formed from coating compositions comprising 1,1-di-activated vinyl compounds.

This method for painting a surface (S62) of a component (6) with a pattern includes at least the following steps consisting in applying a first coating product on at least a portion of the surface, automatically applying at least one portion of a mask (12) on a portion (Z62) of the surface, applying a second coating product and on the surface and removing the mask (12). Preferably, the mask (12) is at least partially automatically applied in the form of at least one layer (122, 124, 126) of non-atomized fluid, the layer being obtained by moving (A1) an applicator (16) delivering the non-atomized fluid along the portion (Z62) of the surface (S62) where the mask (12) is to be applied.

A method for painting a component such as a motor vehicle body component includes applying to the component a base coat layer, a pattern such as a decorative strip or a graphic element, and applying a clear lacquer coat. The pattern (7) is applied to the base coat layer without interposing a clear lacquer coat. A corresponding painting facility is provided.

A multi-layer paint film satisfies paint film performance, such as water resistance, impact resistance and the like, required of an automobile paint film and which has excellent paint film appearance is obtained. The method comprises coating an aqueous first base paint (A) over an electrodeposited cured paint film to form a first base paint film, and then coating an aqueous second base paint (B) over the first base paint film without carrying out preliminary drying by heating after forming the first base paint film to form a second base paint film, preliminary drying by heating is carried out after forming the second base paint film, coating a single-liquid type clear paint (C) over the second base paint film to form a clear coat paint film. These three paint film layers are heated and cured at the same time.

Surfacing films and related processes are provided. These films include a first clear coat layer comprising a first crosslinked polyurethane that is the reaction product of an isocyanate; a polyol selected from the group consisting of: a caprolactone polyol, polycarbonate polyol, a polyester polyol, acrylic polyol, polyether polyol, polyolefin polyol, and mixtures thereof; and a hydroxy-functional silicone poly(meth)acrylate; a second clear coat layer comprising a crosslinked polymer that is essentially free of hydroxy-functional silicone poly(meth)acrylate; a bulk layer comprising a thermoplastic polyurethane; and an adhesive layer. The provided films overcome the problem of migration of solvents and other impurities into the polyurethane bulk layer because the clear coat layer is cured, and solvents removed, prior to the coating of the polyurethane bulk layer. Manufacturing of these films can provide substantially faster line speeds and reduced waste.

The object of the present disclosure is to provide an automobile part capable of improving fuel consumption by weight reduction of the part because the impact resistance that can be sufficiently used even in cold regions can be given to a part made of a thinner plastic.

An automobile part obtained by forming a coating film layer on a plastic material comprising a polypropylene resin composition modified with an elastomer component having a thickness of 1.5 to 2.5 mm, wherein said coating film layer is a multilayer coating film obtained by coating and baking the following coating compositions in this order; (a) a primer coating composition having a single film tensile elongation of 5 to 35% at −20° C., (b) a base coating composition containing a coloring agent and, (c) a clear coating composition containing at least a linear acrylic polyol (c-1) with a hydroxyl value of 80 to 220 mgKOH/g, a crosslinked acrylic resin (c-2) containing 2 to 30 parts by weight of polyfunctional monomer (c-2-1) with 2 to 4 radically polymerizable unsaturated groups per a molecule and 98 to 70 parts by weight of monofunctional monomer (c-2-2) with one polymerizable unsaturated group as a constituent unit, and having a glass transition point of 70 to 120° C., and a curing agent (c-3), and wherein the coating film layer has a Dupont impact strength of 4.9 J or more at −30° C.

A multi-layer coating includes: a first basecoat layer applied over at least a portion of a substrate; and a second basecoat layer applied over the first basecoat layer. The first basecoat layer and second basecoat layer are formed from compositions having a polyhydrazide and core-shell particles dispersed in aqueous mediums. The core-shell particles of the first basecoat composition includes (1) a polymeric core at least partially encapsulated by (2) a polymeric shell comprising urea linkages, and keto and/or aldo functional groups. The polymeric core of the core-shell particles of the first basecoat composition and the second basecoat composition are each independently covalently bonded to at least a portion of the polymeric shell of the core-shell particles.
