Examples of dispersing agents well suited to the invention, there may be mentioned: Preferably, the maximum size of the dd constituting the anticorrosion pigment is 30 microns. The anticorrosion pigment is selected from non-toxic compounds, preferably from the group consisting of: Anticorrosive aqueous phase coating compositions and use thereof for protecting metal elements.
The dispersant content is preferably between 0. For the sake of simplicity, in response to this request, the abbreviation “TBS” shall mean the resistance to salt spray. 29 compositions of Examples 1 and 2, have not been clouded to allow better observation of corrosion likely to appear at the interface between the film and the substrate.
ART Most anticorrosion paints available on the market today include two-component epoxy or alkyd binder, one or organic solvents and one or anticorrosion pigments such as zinc chromate or strontium metaborates or phosphates.

Synonyms and antonyms of Acronal in the German dictionary of synonyms. Subsequently, the pigment paste obtained in C was added in portions to the mixture obtained. In addition, according to an essential feature of the present invention, the hydrophobic film forming binder, therefore capable of r influencing the water permeability of the dry film of the anticorrosive coating must meet the test conditions. Preference is given to the use of transparent coating materials used in the field of paint chemistry, such as waterborne or solventborne clearcoats, transparent powder coatings, transparent powder slurry coatings, solvent-containing and aqueous two-component clearcoats, etc.
As C 1 -C 8 -alkyl meth acrylate monomer units, the acrylate polymer of component i employed in accordance with the invention can comprise the linear and branched-chain derivatives, with methyl meth acrylate, ethyl meth acrylate, n-propyl and isopropyl meth acrylate, n-butyl and isobutyl meth acrylate and 2-ethylhexyl meth acrylate being preferred.
In addition, the basecoat composition may also include fillers which are customary in the s of paint chemistry. The process of claim 1, wherein the C 1 -C 8 -alkyl meth acrylate monomers of component i are selected from the group consisting of methyl meth acrylate, ethyl meth acrylate, and mixtures thereof.
In fact, if we replace that burden by “10 WoUastokup toilet” in the above examples, TBS anticorrosion coatings made with formulas free of waterproofing agent, has improved significantly.
Examples of suitable organic solvents are naphthalenes, petroleum spirits and alcohols. The test C to select the compounds suitable for the present invention as corrosion inhibitor, in this case the compounds corresponding to the following part numbers:.
A total of two axles have four tires. Transportation costs are relatively low. The car over 8 meters or so is probably about 4 yuan per kilometer. German words that begin with acr. The present invention accordingly provides a process for producing a multilayer coating on a substrate surface, in which.
Protective coating compositions according to the present invention are advantageously presented, prior to use, as a single component. Substrate treating agent for precoated metallic sheet, coated substrate treated metallic sheet coated with the same and precoated metallic sheet excellent in working adhesion of coating film using the same. When curing at ambient temperature, the abovementioned baking time is extended accordingly, and is approximately between 15 and 24 hours.
Acronal D: A binder for textured finishes. | Article Information | J-GLOBAL
The process of claim 1, wherein the transparent topcoat composition of step B is selected from the group xcronal of waterborne clearcoats solventborne clearcoats, transparent powder coatings, transparent powder slurry coatings, solvent-containing two-component clearcoats and aqueous two-component clearcoats. The acronao composition is applied to a substrate surface coated with a customary primer surfacer. Compounds having a corrosion inhibiting activity are well known in the art.
The compositions according to the invention are useful for coating metal elements including iron, particularly ferrous metal parts in the automotive industry to provide protection against corrosion.
Acronal 290 D
A mixture of 7. After 15 mins of grinding, when the mixture is perfectly homogeneous, is incorporated with gentle stirring, the proportion of water remaining and the additional antifoam.
A multilayer-coated substrate, where the coating is applied to the substrate surface, such that A an aqueous coating composition comprising as film-forming agent an aqueous polymer dispersion is applied as basecoat composition to a substrate caronal coated with a primer surfacer. The drying conditions after application, can be varied and determined depending on the chemical nature of the film-forming binder and its ability to form a dry film.
Such coating compositions usually comprise an aqueous dispersion of a film-forming polymeric binder, one or more corrosion inhibiting pigments, and optionally one or more additives, for example thickener. The transparent topcoat can be applied by customary methods which are known in the prior art. Method for preparing color-clear composite coatings having resistance to acid etching.
Use Of Moo3 as corrosion inhibitor, and coating composition containing such an inhibitor. The coating composition can be cured at ambient temperature. As indicated above, the carriers contemplated for anticorrosive coating compositions of the present invention are varied. The amount of anionic emulsifier is from 0. Acronap desired transparent coating materials can be applied to the basecoat, examples being aqueous or solvent-containing coating materials or else powder coatings, which is not possible in the processes known from the prior art.
Indeed, under these conditions, the corrosion resistance was further improved ie resistance to salt spray according to standard ISO and held in deionized water by immersion for hours according to the test method D27 September entitled “paint coatings – the immersion resistor in acronak Ford tray and prescribed for Peugeot and automobiles Citroen. According to the invention, the anticorrosive coating compositions in aqueous phase have a basic pH: Water-dilutable coating compositions for base coats for wet-on-wet application of clear coat on base coat.
Waterbased methylol meth acrylamide acrylic polymer and polyurethane containing coating composition.
