摘要:
The present invention provides an improved multi-layer composite of two or more polymeric layers at least one of which is formed from a thermosetting composition. The composite includes at least a first polymeric layer formed on a substrate and a second polymeric layer over the first polymeric layer, wherein in the absence of a boron-containing compound, the first and second polymeric layers have poor interlayer adhesion. The improvement resides in the inclusion of at least one boron-containing compound in one or both of the first and second polymeric layers in an amount sufficient to improve the interlayer adhesion between the first and second polymeric layers. Also provided is an improved curable coating composition used to form a multi-layer composite coating of two or more cured coating layers, at least one of which is formed from the thermosetting composition. Related methods and coated substrates are also provided.

A method of protecting the paint on a vehicle from being chipped, scratched or corroded, comprising the steps of: (a) masking off those parts of the vehicle that are not to be coated; (b) spraying the remaining parts of the vehicle with a clear, protective coating to a thickness of four to fourteen mils or to a thickness that is three to five times the thickness of an OEM clear coat; (c) allowing the vehicle to air dry or force curing the vehicle with heat lamps; and (d) unmasking the vehicle. A spray-on protection film comprising a mixture of polyester resins and a high solids aliphatic polyisocyanate resin hardener, wherein the film is sprayed onto all or part of a vehicle to a thickness of four to fourteen mils or to a thickness that is three to five times the thickness of an OEM clear coat.

A thermosetting composition that includes an ungelled copolymer composition and a crosslinking agent. The ungelled copolymer composition includes a functional group-containing copolymer that includes segments of alternating residues derived from a donor monomer composition comprising an acceptor monomer composition. The donor monomer composition includes one or both of isobutylene and diisobutylene, and the acceptor monomer composition includes acrylic monomers and monomers containing functional groups. The ungelled copolymer composition is substantially free of transition metals and Lewis acids, and the copolymer is substantially free of maleate-type monomer residues and fumarate-type monomer residues. The crosslinking agent has at least two functional groups that are reactive with the functional groups of the copolymer. The thermosetting composition may be in liquid, powder, or dispersed form and may be applied by traditional or electrocoating methods.

The invention provides a composition containing a colorant and a sealer which is applied to a floor surface for the purpose of coloring or tinting the floor. The sealer may be an acrylic copolymer or a styrene acrylic copolymer. The composition can be applied to a variety of floor surfaces, including vinyl tile and concrete. The solids content of the composition varies depending upon whether a tint or solid color is desired. In addition, the invention provides a method of applying and maintaining a hard floor coating. The method includes preparing the floor surface, sealing the floor surface, applying a colored polymer to the sealed surface, and applying a clear, non-epoxy floor finish.
摘要:
The present invention provides coatings comprising a substrate coated with one or more than one colored primer layer comprising one or more than one binder chosen from a resinous or (co)polymeric primer or adhesion promoter, and one or more than one basecoat color layer thereon, wherein the color of each of the basecoat layer and the colored primer layer are the same. Preferred coatings comprise single colored primer and basecoat color layers to make color coatings having a reduced film build, i.e. two layers. Binders for making primer coating layers may comprise weatherable primer resins or (co)polymers, or may comprise adhesion promoters chosen from modified isotactic polypropylene (MPP), MPP copolymers, chlorinated polyolefin (CPO), and their mixtures with alkyds or acrylics. In addition, the present invention provides methods for making coatings on substrates such as thermoplastic polyolefin (TPO), polyolefin containing or metal substrates. Accordingly, the present invention provides color coatings that exhibit improved hiding of dark color or black substrates, such as automotive plastics like TPO, made from simplified coating methods.

The present invention provides a coating method comprising steps of applying a metallic base coating (A) containing a effective pigment on a surface to be coated and subsequently applying a colored clear coating (B) thereon, wherein the metallic base coating (A) forms a coating film having a IV value of 230 or more and a measured value of particle feeling (HG value) on a micro brilliance feeling-measuring apparatus of 60 or less. The method of the present invention is suitable as a top coating for outer panels of automobiles and the like.

A multicoat color and/or effect coating system ML for a primed or an unprimed substrate comprising—lying above one another—(1) a surfacer coat FL which absorbs mechanical energy, and (2) a color and/or effect topcoat DL, or (1) a surfacer coat FL which absorbs mechanical energy, (2) a color and/or effect basecoat BL, and (3) a clearcoat KL, or (1) a color and/or effect basecoat BL and (2) a clearcoat KL, wherein at least one coat, preferably at least two coats, and in particular all coats of the multicoat system ML has or have been produced from a coating material comprising at least one constituent (A) preparable by free-radical polymerization of a) olefinically unsaturated monomers and b) olefinically unsaturated monomers I different than the olefinically unsaturated monomers (a): R1R2C=CR3R4 (I), in which the radicals R1, R2, R3 and R4 each independently of one another are hydrogen atoms or alkyl, cycloalkyl, alkylcycloalkyl, cycloalkyalkyl, aryl, alkylaryl, cycloalkylaryl, arylalkyl or arylcycloalkyl radicals, with the privso that at least two are aryl, arylalkyl or arylcycoalkyl radicals; in an aqueous medium.
摘要:
A composition that includes a non-gelled copolymer that includes one or more residues of a first polymerizable ethylenically unsaturated monomer containing a pendant amide, ester or carboxylic acid group. The nearest neighboring monomer residues of the majority of the first monomer residues along the copolymer molecule do not contain pendant carbonyl functional groups. The amide, ester or carboxylic acid group of the residues of the first monomer are the post polymerization transesterification, transamidification or hydrolysis reaction product of a C1-C4 alkyl ester group in the unreacted first monomer with a compound selected from amine functional compounds and hydroxy functional compounds. The reacted copolymer is substantially free of cyclical structures resulting from the transesterification, transamidification or hydrolysis reaction. The compositions may be thermosetting compositions useful in multi-layer composite coatings.

A method for refinishing an area of an automobile's exterior is disclosed. The method comprises the following the steps: sanding the area of the automobile's exterior which is to be refinished; cleaning the sanded area; applying a layer of primer formed from a liquid primer or a pre-formed sheet of primer to the cleaned area; applying a layer of basecoat formed from a liquid basecoat or a pre-formed sheet of basecoat over the layer of primer; applying a layer of clearcoat formed from a liquid clearcoat or a pre-formed sheet of clearcoat over the layer of basecoat; and sanding and buffing the layer of clearcoat.
