These include silicic acid, magnesium silicate, talc, titanium dioxide and barium sulfate.
E – formation c coatings on ferrous s with adhesion of the metal support at least equal to those obtained with the anti-corrosive paint containing an alkyd or epoxy bicomponent binder and one or more organic solvents in the conditions of NF T of November. 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.
We also share information about the use 920 the site with our social media, advertising and analytics partners. The content of the antifoaming agent is preferably between 0.
The viscosity of the resulting coating material was adjusted with 5 parts by weight of water to mPas.
White exterior and interior wall paint based on Acronal 290D
Advantageously, thanks to the anticorrosive coating composition according to the invention, it is not necessary to add other film-forming binder, such as an epoxy ester, to achieve high performance of the corrosion resistance.
Examples of suitable carboxyl-functional crosslinking agents are carboxylic acids, especially saturated, straight-chain, aliphatic dicarboxylic acids with 3 to 20 carbon atoms in acrona molecule, preference being given to the use of dodecane-1,dioic acid. Another essential component of the compositions according to the present invention is an anticorrosive pigment forming compounds with iron II and III ions which are very sparingly soluble or insoluble in water.
The transparent topcoat can be applied by customary methods which are known in the prior art. By finely divided inorganic fillers is meant fillers with a maximum grain size not exceeding 30 microns, preferably less than or equal to 5 microns. Examples of anionic emulsifiers are the alkali metal salts of sulfuric acid half-esters of alkylphenols or alcohols, and the sulfuric acid half-esters of ethoxylated alkylphenols or ethoxylated alcohols, preferably the alkali metal salts of the sulfuric acid half-ester of a nonylphenol reacted with from 4 to 5 mol of ethylene oxide per mole, of alkyl- or arylsulfonate, sodium lauryl sulfate, sodium lauryl ethoxylate sulfate and secondary sodium alkanesulfonates whose carbon chain includes carbon atoms.
Substrate treating agent for precoated metallic sheet, coated substrate treated metallic acrlnal coated with the same and precoated metallic sheet excellent in working adhesion of coating film using the same. As indicated above, the present invention avoids the use of toxic anti-corrosive pigments. Inquire Now Add to My Favorites.
The compositions according to the invention may also contain, advantageously, finely divided mineral fillers. Arconal the anti-corrosive pigments which led to the highest performance in resistance to saline mist, when they are associated with the aforementioned components a – foptionally g selected include: These coatings are formed by drying and optionally curing the applied composition. Examples of coalescing agents suitable for the invention include glycols, ethers and glycol esters and paraffinic compounds.
The rheological auxiliary is intended to give the basecoat composition the desired viscosity acrona, at the generally alkaline pH that is employed.

Examples of toxic anti-corrosive pigments that are recommended not to use include chromates, molybdates, lead oxides, pigments containing a 2990 such as tungsten, lead, and boron compounds. Protective coating compositions according to the present invention are advantageously presented, prior to use, as a single component.
The anti-foaming agents that may be used in the context of the present invention are well-known products of the art. No metal support Phosphate Phosphate Phosphate Acrronal No Phosphated Non-ferrous phosphate, phosphate, 209, phosphated, degreased and defatted and degreased and dried degreased and dried dried dried. Es handelt sich um eine For the sake of simplicity, in response to this request, the abbreviation “TBS” shall mean the resistance to salt spray.
Therefore, it is advantageously between 0. Advantageously, the anticorrosion pigment used in the context of the invention preferably contains one or more sparingly soluble oxides in water and alkaline such as zinc oxide or aluminum oxide. Thus, the adhesion of coatings containing pure zinc phosphate as an anti-corrosion pigment on ferrous substrates is poor and the corrosion resistance of such coatings is also poor. The main v of these paintings is their pH is in the range of 4.
Meaning of “Acronal” in the German dictionary
The pigment can be added in any desired form, for example as an aqueous slurry or as a paste. The solids content varies with the intended use of the coating compositions. Any desired transparent coating materials can be applied to the basecoat, examples being aqueous or acroanl coating materials or else powder coatings, which is not possible in the processes known from the prior art. The present invention relates to anticorrosive coating compositions in aqueous phase.
Zinc-rich coating excellent in corrosion-resistant property and coated metal plate. Coatings comprising the basecoat used in accordance with the invention can be repaired without problems in cases of damage.
Method for coating metal surfaces using an aqueous compound having polymers, the aqueous compound, and use of the coated substrates. II – Selection of corrosion inhibitors test O Attack time was determined by corrosion in the test conditions C described above to quantify the effectiveness of chemical compounds as a corrosion inhibitor.
As pigments the basecoat composition can comprise customary pigments employed for coating car bodies, such as, for example, special-effect pigments and also organic and inorganic color-imparting pigments.
The compositions corresponding to Examples were applied to phosphated plates, to achieve a dry thickness of about 35 microns. 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. Preferably used polyurethanes, associative acrylic polymer or a combination of these two compounds.
As further component the basecoat composition may include film-forming auxiliaries. Zum Aufkleben des Calico verwendeten wir Acronal 14 D, 1: Anticorrosion coating compositions in the aqueous phase and their use in the protection of metallic elements.
The compositions according to the invention can be applied for example by dipping or casting, brushing, using an applicator bar or spray gun.
Surprisingly it has been found that the novel process for producing multilayer coatings is highly suited to the production of multilayer coatings on substrates and for repairing multilayer coatings, especially for car bodies. Waterbased coating compositions of methylol meth acrylamide acrylic polymer, polyurethane and melamine crosslinking agent.
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 surface coated with a primer surfacer.
If you buy this car, see what you do, run the goods, run what way, and finally look at the price. As thickener component ii in the basecoat composition use is made in accordance with the invention of acrylate copolymers having nonassociative groups, comprising C 1 -C v -alkyl meth acrylate and meth acrylic acid as monomer units.
This agent is primarily used to deagglomerate the anti-corrosive pigments and various other solid additives may be present in these compositions. Mineral fillers that may be used are well-known products of the art.
