Definitions
- the invention relates to a method for producing multi-layer coatings.
- Basecoat and clearcoat are preferably applied wet-on-wet, i.e. after a flash-off time, if necessary with heating, and after subsequent application of a clear coat, the basecoat is baked together with the latter.
- Processes which reduce further baking steps have also become known, in which electrophoretically applied primer and filler layer are applied by the wet-on-wet process, as described, for example, in DE-A-41 26476 or EP-A-0595 186.
- the filler layers must be applied in a dry film thickness of 30 ⁇ m and more, which is common for filler coatings.
- the object of the invention is to provide a process for the production of multi-layer coatings, in particular motor vehicle coatings, with an overall property level comparable to that of the prior art, but with a reduced layer thickness
- the object is achieved by a process for the multi-layer coating of electrically conductive substrates by electrophoretic deposition of a first coating layer from an electrophoretically depositable aqueous coating agent and subsequent application of further coating layers, which is characterized in that wet-on the first coating layer obtained by electrophoretic deposition wet a second coating layer of a first color and / or effect basecoat coating agent is applied and the first and second coating layers thus obtained are baked together, whereupon a third coating layer of a second color and / or effect basecoat coating agent is applied and wet-in wet a fourth coating layer is applied from a clear lacquer coating agent and the third and fourth coating layers are baked together, the total dry layer thickness (sum of the layer thickness) of the second and third coating layers produced from the basecoat coating compositions is between 15 and 40 ⁇ m, preferably between 20 and 35 ⁇ m, and the proportion of the second coating layer is between 20 and 50%, preferably between 25 and 40%, of the total dry layer thickness of the second and third
- the method according to the invention makes it possible to directly onto the first one that has not yet been burned in Applying a basecoat coating agent and baking this together with the electrophoretically deposited coating layer, filler layers or other intermediate layers being omitted.
- the method according to the invention is preferably carried out in such a way that the joint baking of the third and fourth coating layers takes place at a temperature which is equal to, or particularly preferably falls below, the baking temperature prevailing when the first and second coating layers are jointly baked.
- anodically or cathodically depositable electrodeposition lacquers which are known per se and which are not subject to any particular restriction, can be used as the electrophoretically depositable coating agents to produce the first coating layer, namely a primer. .
- aqueous coating compositions with a solids content of, for example, 10 to 20% by weight.
- the solid is formed from binders customary for electrocoating, which carry ionic groups or groups which can be converted into ionic groups and groups capable of chemical crosslinking, as well as pigments, fillers and / or conventional additives.
- the ionic or convertible groups can be anionic or convertible groups, e.g. acidic groups such as -COOH groups or cationic or convertible groups, e.g. basic groups such as amino, ammonium, e.g. be quaternary ammonium groups, phosphonium and / or sulfonium groups. Binders with basic groups are preferred. Nitrogen-containing basic groups are particularly preferred.
- These groups can be quaternized or they are at least partially treated with a common neutralizing agent, an acid, e.g. an organic monocarboxylic acid, e.g. Formic acid or acetic acid converted into ionic groups.
- a common neutralizing agent an acid, e.g. an organic monocarboxylic acid, e.g. Formic acid or acetic acid converted into ionic groups.
- anionic which can be used in the process according to the invention
- Group-containing anodically depositable electrocoat binders and paints are described in DE-A-2824418. It is about for example, binders based on polyesters, epoxy resins, poly (meth) acrylates, maleate oils or polybutadiene oils with a weight average molecular weight of, for example, 300 to 10,000 and an acid number of 35 to 300 mg KOH / g.
- the binders carry -COOH, -SO ⁇ H and / or -P0 3 H 2 groups. After neutralization of at least some of the acidic groups, the resins can be converted into the water phase.
- the lacquers can also contain conventional crosslinking agents, for example triazine resins, crosslinking agents which contain groups capable of transesterification or blocked polyisocyanates.
- cathodic electrocoat materials based on cationic or basic binders can preferably be used in the process according to the invention.
- Such basic resins are, for example, primary, secondary or tertiary amino group-containing resins whose amine numbers are e.g. are 20 to 250 mg KOH / g.
- the weight average molecular weight (Mw) of the base resins is preferably from 300 to 10,000.
- Examples of such base resins are amino (meth) acrylate resins, amino epoxy resins, amino epoxy resins with terminal double bonds, amino epoxy resins with primary OH groups, aminopolyurethane resins, amino group-containing polybutadiene resins - Carbon dioxide amine conversion products.
- base resins can be self-crosslinking or they are used in a mixture with known crosslinking agents.
- crosslinkers are aminoplast resins, blocked polyisocyanates, crosslinkers with terminal double bonds, polyepoxide compounds or crosslinkers which contain groups capable of transesterification.
- base resins and crosslinking agents which can be used in cathodic immersion baths are in EP-A-0082 291, EP-A-0 234 395, EP-A-0227975, EP-A-0178531, EP-A-0333327, EP-A-0310971, EP-A-0 456270, US 3922253, EP-A-0261 385, EP-A-0 245 786, DE-A-33 24211, EP-A-0414 199, EP-A-0476514 described. These resins can be used alone or in a mixture. So-called "non-yellowing" CTL systems are preferably used, which prevent yellowing or discoloration of the multi-layer coating when baked. For example, these are KTL systems that crosslink using specially selected blocked polyisocyanates, such as in EP-A-0 265363.
- the electrocoat material (ETL) coating agent can contain pigments, fillers and / or additives customary in coating.
- the usual inorganic and / or organic pigments and fillers are suitable as pigments and fillers. Examples are carbon black, titanium dioxide, iron oxide, kaolin, talc or silicon dioxide.
- the pigments can be dispersed into pigment pastes, e.g. using known paste resins. Resins of this type are familiar to the person skilled in the art. Examples of paste resins that can be used in KTL baths are described in EP-A-0183025 and in EP-A-0469497.

- film-forming binders for example, polyester, Polyurethane and / or poly (meth) acrylate resins can be used.
- the selection of the crosslinking agents which may be present is not critical, it depends on the functionality of the base resins, ie the crosslinking agents are selected such that they have a reactive functionality which is complementary to the functionality of the base resins.
- Examples of such complementary functionalities between base resin and crosslinker are: carboxyl / epoxy, hydroxyl / methylol ether directly bonded to carbon or silicon, hydroxyl / free isocyanate directly bonded to carbon or silicon, hydroxyl / blocked isocyanate directly bonded to carbon or silicon, (meth) acryloyl / CH-acidic
