The invention provides a method for the at least partial removal of one or more polymeric coating layers from a coated substrate having at least one coated surface. The method includes generating at least one reactive species in an ionized gas stream discharged at atmospheric pressure; and placing the coated surface in the ionized gas stream. The at least one reactive species reacts with the one or more polymeric coating layers such that one or more coating layers is at least partially removed from the coated surface of the substrate at atmospheric pressure.

Methods for removal of polymeric coating layers from coated substrates

Articles are disclosed wherein a color-imparting non-hiding coating layer is deposited on a surface thereof. The coating layer is deposited from a protective coating composition comprising color-imparting particles having a maximum haze of about 10% and a film-forming resin. Methods of using the coatings, and the substrates coated therewith, are also disclosed.

Coated articles and multi-layer coatings

Compositions are disclosed. The compositions include a binder, a transparent or semi-transparent colorant having an average particle diameter of greater than 150 nanometers; and at least one member comprising a scattering pigment dispersed in a matrix. Substrates coated with such compositions and methods of coating substrates with such compositions are also disclosed.

Colored compositions with substrate-hiding materials

A method of applying a multi-component coating of a desired composition over a substrate includes providing a coating device in flow communication with a first coating component having a first rheological profile and at least one second coating component having a second rheological profile. The method further includes defining a desired ratio of the first and at least one second coating components to provide a coating of a desired composition, and selecting the rheological profiles of the first and at least one second coating components such that the coating components are supplied at a desired ratio.

Method and apparatus for mixing and applying a multi-component coating composition

A curable film-forming composition is provided that on curing produces a coating, comprising in a medium (i) 10 to 90 percent by weight based on the total weight of resin solids in the film-forming composition of a crosslinking agent; (ii) 10 to 90 percent by weight based on the total weight of resin solids in the film-forming composition of a polymer containing a plurality of functional groups reactive with the crosslinking agent; and (iii) 20 to 85 percent by volume based on the total volume of the film-forming composition of particles having a mean particle size less than 100 nm. The particles further have an index of refraction sufficiently similar to that of the polymer of (ii) to minimize haze, and have an affinity for the medium sufficient to keep the particles suspended therein. The affinity of the particles for the medium is greater than the affinity of the particles for each other, thereby preventing agglomeration of the particles within the medium. The film-forming compositions exhibit improved scratch (mar) resistance compared to compositions of the prior art, as well as improved sag resistance when compared to similar coating compositions prepared without the particles. A multi-component composite coating composition is also provided. The coating composition comprises a pigmented film-forming composition serving as a base coat and a clear film-forming composition serving as a transparent topcoat over the base coat. The transparent topcoat, or clear coat, is derived from the curable film-forming composition described above.

Curable film-forming composition exhibiting improved scratch resistance

Fast drying clear coat composition

Curable compositions containing novel polysiloxanes having various reactive functional groups are disclosed. The curable compositions are useful as both ambient-cured and thermally-cured coating compositions which provide such properties as excellent appearance, mar resistance, acid etch resistance, adhesion, pot life, improved tack time, mar resistance and corrosion resistance.

Curable compositions based on functional polysiloxanes

Coating compositions comprising (a) a carboxyl functional adduct which is the reaction product of (i) a compound, polymer or oligomer containing pendant and/or terminal hydroxyl or epoxy functional groups and (ii) citric acid or citric acid anhydride; and (b) an anhydride functional curing agent are disclosed. The coating compositions have accelerated tack-free times and enhanced adhesion to zinc-coated steel substrates without the use of a chrome-containing wash primer.
