Definitions
- the present invention relates to new, solvent-containing mixtures which are curable physically or thermally and / or with actinic radiation.
- the present invention relates to a new process for the production of physically or thermally and / or actinic radiation-curable, solvent-containing mixtures.
- the present invention relates to the use of the new, solvent-containing mixtures curable physically or thermally and / or with actinic radiation as coating materials, adhesives and sealants.
- Solvent-containing mixtures curable physically or thermally and / or with actinic radiation have long been known.
- the known solvent-containing mixtures can be pigmented or unpigmented. They are used as pigmented and unpigmented coating materials, adhesives and sealants, but in particular as pigmented and unpigmented coating materials.
- the pigmented and unpigmented coating materials can be used for a wide variety of purposes. For example, they can be used for the painting of motor vehicle bodies and parts thereof, of motor vehicles inside and outside, buildings inside and outside, doors, windows and furniture as well as for the industrial painting of the coating of coils, containers, packaging, small parts, serve electrical components and white goods. Particularly high demands are made of the pigmented and unpigmented coating materials when they are used for the initial painting of motor vehicle bodies and parts thereof (OEM) and for the repair painting of motor vehicles indoors and outdoors. The highest demands are placed on the first painting and refinishing of luxury cars. In general, automotive coatings are considered to be the top products in the coatings industry (cf. Römpp Lexikon Lacke und Druckmaschine, Georg Thieme Verlag, Stuttgart, New York, 1998, "Automobillacke", pages 49 and 50).
- the pigmented coating materials can be used to produce filler coatings and stone chip protection primers, solid-color top coats and basecoats.
- the unpigmented coating materials are used to produce clear coats.
- This multi-layer coating is referred to here and below as a color and / or effect multi-layer coating.
- the clear coats form the outermost layer, they protect the coats underneath and shape the overall appearance (appearance) of the multi-coat paint and / or effect coating by deepening the visual effect of the base coat.
- the clearcoats are responsible for optical, mechanical and chemical properties, such as gloss, distinctness of image (DOI), hardness, scratch resistance, weather stability, chemical stability and etch resistance.
- the non-pigmented coating materials which can provide clear coats of this application-related property profile, must have a very good flow and a very low tendency to run during application and curing, so that clear coat layers free of surface defects occur. These must not tend to form stoves, pinholes, cracks and orange peel structures during hardening.
- the object of the present invention is to provide new, solvent-containing, pigmented and unpigmented mixtures which are curable physically or thermally and / or with actinic radiation and which no longer have the disadvantages of the prior art, but which are outstanding as pigmented and unpigmented coating materials, Let adhesives and sealants, especially pigmented and unpigmented coating materials, or use them to make them.
- the pigmented coating materials are said to be outstandingly suitable as fillers, solid-color topcoats or basecoats for the production of color and / or effect-giving multi-layer lacquers which include filler lacquers or stone chip protection primers and solid color lacquers or filler lacquers or stone chip protection primers, basecoats and clearcoats.
- the unpigmented coating materials are said to be particularly suitable as clear lacquers for producing color and / or effect multi-layer coatings.
- the clearcoats should be able to be used for the production of these color and / or effect multicoat paint systems by integrated wet-on-wet processes, in which at least one dried, but not fully cured basecoat film is covered with a clearcoat film, after which the two layers together be hardened.
- the resulting filler coatings or stone chip protection primers, solid-color top coats, basecoats and clear coats, but especially clear coats, should have an excellent, trouble-free surface without stoves, pinholes, cracks and orange peel structures.
- the clear coats should have a higher gloss, a higher distinctness of image (DOI) and better appearance than the clear coats of the prior art.
- the clear coats should be hard, scratch-resistant. activity, weather stability, chemical stability and etch resistance correspond to the clearcoats of the prior art.

- the coating materials, adhesives and sealants according to the invention which contained the aromatic-free solvent mixtures to be used according to the invention, provided coatings, adhesive layers and seals with very good to excellent performance properties.
- the coatings according to the invention had excellent, trouble-free surfaces without stoves, pinholes, cracks and orange peel structures.
- the clearcoats of the invention surprisingly showed a higher gloss, a higher degree of differentiation (DOL) and better appearance than the clearcoats of the prior art.
- the clearcoats of the invention corresponded in their hardness, scratch resistance, weathering stability, chemical stability and etch resistance in full to the clearcoats of the prior art.
- free of aromatics means that the aromatic-free solvent mixtures to be used according to the invention have an aromatic solvent content of less than 1.0% by weight, preferably less than 0.1% by weight and in particular below the gas chromatographic detection limit.
- “completely free from aromatic solvents” means that the mixtures according to the invention, based on their total amount, contain less than 1.0% by weight and in particular less than 0.1% by weight of aromatic solvents.
- the aromatic solvent content is below the gas chromatographic detection limit.
- “Essentially free from aromatic solvents” means that the mixtures according to the invention may contain a certain aromatic solvent content which, based on its total amount, is> 1.0% by weight, but this content does not apply to those to be used according to the invention aromatic-free organic solvents medium goes back, but to aromatic solvents which are forcibly "carried in” by the other constituents of the mixtures according to the invention, such as binders or crosslinking agents.
- actinic radiation means electromagnetic radiation, such as near infrared (NIR), visible light, UV radiation and X-rays, in particular UV radiation, and corpuscular radiation, such as electron beams.
- NIR near infrared
- UV radiation visible light
- UV radiation ultraviolet radiation
- corpuscular radiation such as electron beams.
- Hildebrand solubility parameter ⁇ [(cal / cm 3 ) 172 ] is defined in Römpp Lexikon Lacke und Druckmaschine, Georg Thieme Verlag, Stuttgart, New York, 1998, "Solubility parameters", pages 361 to 365.
- HBI Hydrogen Bonding Index
- “Physical hardening” is understood to mean the hardening of a layer of the mixture according to the invention by filming, the connection within the coating via loop formation of the polymer molecules of the binders (for the term cf. Römpp Lexikon Lacke und Druckmaschine, Georg Thieme Verlag, Stuttgart, New York, 1998, “Binders”, pages 73 and 74), or the filming takes place via the coalescence of binder particles (cf. Römpp Lexikon Lacke und Druckmaschine, Georg Thieme Verlag, Stuttgart, New York, 1998, “Här- tion «, pages 274 and 275). No crosslinking agents are usually necessary for this. If necessary, the physical hardening can be supported by atmospheric oxygen, heat or by exposure to actinic radiation.
- the mixtures according to the invention can furthermore be thermally curable. Here, they can be self-cross-linking or cross-linking.
- self-crosslinking denotes the property of a binder to undergo crosslinking reactions with itself.
- the prerequisite for this is that both types of complementary reactive functional groups which are necessary for thermal crosslinking or reactive functional groups are already present in the binders of the mixtures according to the invention
- mixtures according to the invention are designated as crosslinking in which one type of the complementary reactive functional groups is present in the binder and the other type is present in a hardener or crosslinking agent Römpp Lexikon Lacke und Druckmaschine, Georg Thieme Verlag, Stuttgart, New York, 1998, “Hardening", pages 274 to 276, especially page 275, below.
- the mixtures according to the invention can be curable with actinic radiation.
- curing takes place via groups which contain bonds which can be activated with actinic radiation.
- the mixtures according to the invention can be curable thermally and with actinic radiation. If thermal and curing with actinic radiation are used together in a mixture according to the invention, one also speaks of “dual cure” and “dual cure mixture”.
- the mixtures according to the invention can be one-component (1K) systems.
- One-component (1K) systems are understood as thermal or thermal and with actinic radiation-curing mixtures according to the invention in which the binder and the crosslinking agent are present side by side.
- the prerequisite for this is that the two components only crosslink with one another at higher temperatures and / or when irradiated with actinic radiation.
- the mixtures according to the invention can be two- or multi-component systems.
