The invention provides coating processes for producing finished fibrous panels comprising applying a prime coat onto at least one side of the fibrous panel by curtain coating; and applying a finish coat over the prime coat by spray coating.

Disclosed is a method for treating a grained material. A nonlimiting example of the method includes the operations of providing a workpiece having grains, exasperating a surface of the workpiece to open the grains, applying at least one coat of a base paint to the exasperated surface, applying at least one layer of clear coat on the base paint, applying at least one of a glaze and a paint on the clear coat, and surface treating to reveal grains of the workpiece. Disclosed also are items of furniture and sheet materials treated by the aforementioned process.

Waterborne top coat compositions, processes for preparing such compositions, and methods for forming top coats on substrates are provided. In an embodiment, a waterborne top coat composition includes water, pigment(s) and resin solids. The resin solids comprise about 60 to 100 wt. % of binder solids and 0 to about 40 wt. % of crosslinker solids, the binder solids comprising about 1 to about 40 wt. % of a urethanized polyester/(meth)acryl copolymer hybrid binder having a hydroxyl number of about 30 to about 200 mg KOH/g and a carboxyl number of about 8 to about 50 mg KOH/g, and about 60 to about 99 wt. % of one or more additional binders, the sum of the respective wt. % in each case equaling 100 wt. %.

Described herein is a method of using organic carboxylic acids having 1 to 10 carbon atoms in preparation of aqueous basecoat materials for the purpose of improving the adhesion of the aqueous basecoat materials to overbaked clearcoat materials. Also described herein is a method for producing a muilticoat paint system, where a basecoat material is applied directly to an overbaked clearcoat film.

Multi-layer coatings comprising polymerization reaction products of 1,1-di-activated vinyl compounds are described. Also provided are processes for coating substrates with curable compositions comprising 1,1-di-activated vinyl compounds. Also provided are articles coated with this composition.

Described herein is a method of using aromatic and/or araliphatic carboxylic acids in preparation of aqueous basecoat materials for the purpose of improving the adhesion of the aqueous basecoat materials to overbaked clearcoat materials. Also described herein is a method for producing a multicoat paint system, where a basecoat material is applied directly to an overbaked clearcoat film.

Provided herein is a process for the pretreatment coating and subsequent lacquering of plastics substrates, wherein a pretreatment layer is produced on a plastics substrate via application, onto the plastics substrate, of a solution or dispersion including at least one organic solvent (L) and, dispersed or dissolved therein, at least one plastic (K), and subsequent evaporation to remove the organic solvent. Then a lacquer layer is produced on the pretreated plastics substrate.

Multi-layer coatings comprising polymerization reaction products of 1,1-di-activated vinyl compounds are described. Also provided are processes for coating substrates with curable compositions comprising 1,1-di-activated vinyl compounds. Also provided are articles coated with this composition.

The present invention relates to multicoat paint systems comprising basecoats and clearcoats with high solids fractions that each comprise at least one sulfonic acid compound of formula (I) or formula (II). The invention further relates to a method of producing these multicoat paint systems and to their use, and also to substrates coated with the multicoat paint system. The invention relates, furthermore, to the use of the sulfonic acid compounds of formula (I) and formula (II) in basecoats and clearcoats with high solids fractions.

A marked substrate including a solid substrate surface such as, for example, a road surface having disposed thereon a first coating including a pigment and a first binder polymer, the first coating having a dry film thickness of from 10 microns to 5000 microns; the first coating having disposed thereon, a clear second coating including from 75% to 100%, by weight based on the weight of the clear coating, nanosilica and from 0% to 25%, by weight based on the weight of the clear coating, second binder polymer; the clear second coating having a dry film thickness of from 1 to 10 microns is provided. A method for providing the marked substrate is also provided.
