Definitions

  • the invention relates to the use of dimerdiol (meth) acrylates with a degree of esterification of at least 50% as matting agents for self-curing or radiation-curable coating systems such as lacquers, coating compositions and the like.
  • the matting agents known from the prior art are practically exclusively solids.
  • WO 01/04217 describes combinations of silicas with waxes as matting agents, the compositions having to meet certain conditions with regard to particle size and pore volume.
  • the particle size of solid matting agents varies within wide limits.
  • US-A-5316843 describes a combination of organic and inorganic solids with grain sizes below 10 ⁇ m
  • US-A-4927710 discloses acrylic fibers with a length of up to 3 mm as matting agents.
  • the layer thickness of the hardened coating must be smaller than the grain size of the solid used as matting agent so that the matting effect occurs at all. If thicker layers are applied before the hardening process, the matting effect only occurs if either the layer thickness of the coating agent falls below the grain size due to its shrinkage during the hardening process or if the hardening process takes place in a form that enables the solid matting agent the layer floats to the surface and causes the matting effect on the surface. In any case, this imposes considerable limits on the formulator.
  • matting agents which are not in solid but in liquid consistency at 20 ° C. and which do not have the disadvantages described above. It should provide for effective matting agents are provided which are particularly suitable for radiation-curing coatings make an impact at the lowest possible concentrations and the viscosity of the coating or paint formulations (in general. Be Anlagenungssyste- of men) have no negative impact.
  • dimer diol (meth) acrylates meet the stated requirements excellently in every respect. Although they have a liquid consistency at 20 ° C, they have a pronounced matting effect and can advantageously be used in conventional self-curing as well as radiation-curable coating systems, which, as the expert knows, include varnishes, coating compositions and the like, as matting additives - just as matting agents.
  • dimer diol (meth) acrylates do not increase the viscosity of the coating systems equipped with them.
  • relatively thick layers of lacquer can also be matted with dimerdiol (meth) acrylates.
  • the invention relates to the use of dimerdiol (meth) acrylates with a degree of esterification of at least 50% as matting agents for self-curing or radiation-curable coating systems, such as lacquers, coating compositions and the like.
  • dimerdiol (meth) acrylates are understood to mean esters of dimerdiol and acrylic and / or methacrylic acid.
  • the dimer diol on which the dimer diol (meth) acrylates are based can be present as such or in technical quality.
  • the dimerdiol (meth) acrylates to be used according to the invention have a degree of esterification of at least 50%.
  • the degree of esterification is preferably at least 80% and in particular at least 92%. In a very particularly preferred embodiment, the degree of esterification is 100%; these are full esters, ie dimerdiol di (meth) acrylates.
  • a degree of esterification of x% means that if 1 mol of dimer diol is used to produce a dimer diol (rneth) acrylate, x% of all the OH groups contained therein are in esterified form.
  • the form of a matting agent which has a liquid consistency at 20 ° C, is also a significant advantage in terms of handling and incorporation into coating systems compared to the usual matting agents, which are solid at 20 ° C.
  • the viscosity of the dimerdiol (meth) acrylates at 20 ° C. is about 300 mPas and therefore, in contrast to the matting agents solid at 20 ° C. known from the prior art, lowers the viscosity of coating systems to which it is added as a matting agent if these Coating systems at 20 ° C have a higher viscosity than 300 mPas. This usually results in easier processing of the coating systems, which is a great advantage for both the formulator and the user.
  • the measurement of the viscosities mentioned is carried out in bulk according to Brookfield (model LV / DV-II +) at 20 ° C. with spindle 63 at 20 rpm.
  • Dimerdiol (meth) acrylates can be obtained, for example, by esterifying dimerdiols with acrylic acid or methacrylic acid or mixtures of acrylic and methacrylic acid.
  • the dimer diols can be used as such or in technical quality (see below).
  • Dimer diols have long been known and commercially available compounds which are obtained, for example, by reducing dimer fatty acid esters.
  • the dimer fatty acids on which these dimer fatty acid esters are based are carboxylic acids which are accessible by oligomerizing unsaturated carboxylic acids, generally fatty acids such as oleic acid, linoleic acid, erucic acid and the like.
  • the oligomerization is usually carried out at elevated temperature in the presence of a catalyst composed of, for example, alumina.
  • the substances obtained - technical quality dimer fatty acids - are mixtures, with the dimerization products predominating.
  • dimer fatty acids are commercially available products and are offered in various compositions and qualities. There is extensive literature on dimer fatty acids. The following articles are cited as examples: Fette & ⁇ le 26 (1994), pages 47-51; Specialty Chemicals 1984 (May issue), pages 17, 18, 22-24. Dimer diols are well known in the art. As an example, reference is made to a more recent article in which the manufacture, structure and chemistry of the dimer diols are dealt with: Fat Sei. Technol. 95 (1993) No. 3, pages 91-94.
  • dimer diols are preferred as raw materials for the production of dimer diol (meth) acrylates which have a dimer content of at least 70% and in particular 90% and in which the number of carbon atoms per dimer diol molecule is predominantly in the range from 36 to 44.
  • the dimer diol (meth) acrylates to be used according to the invention can be metered in without problems to conventional coating systems. For example, they can be introduced into conventional coating systems by stirring and distributed homogeneously therein.
  • the amount of dimerdiol (meth) acrylates in coating systems can be selected by the formulator depending on the technical requirements. They are preferably in the range from 1 to 25% by weight, preferably 2 to 15% by weight, and in particular 3 to 10% by weight, based on the totality of the coating system.
  • the matting effect increases with increasing content of dimerdiol (meth) acrylate in the coating systems.
  • the dimer diol (meth) acrylates can also be used in combination with other matting agents. This can lead to an intensification of the matting effect.
  • the matting effect of the dimer diol (meth) acrylates was observed on different substrates such as glass, metal, wood, paper, ceramic, plastic. It is particularly pronounced on glass. Polyester acrylates, epoxy acrylates or urethane acrylates as well as all conceivable combinations thereof can be used as the basic formulation for radiation-curable, matting coating systems.
  • the invention further relates to coating systems containing dimerdiol (meth) acrylates with a degree of esterification of at least 50%.
  • the dimerdiol (meth) acrylates fulfill the function of a matting agent in these coating systems.
  • Another object of the invention is a process for the production of coatings, metering into conventional self-curing or radiation-curable coating systems such as paints, coating compositions and the like additives of the dimer diol (meth) acrylate type with a degree of esterification of at least 50% and then curing.
  • the dimer diol (meth) acrylates are added to the coating systems in an amount of 1 to 25% by weight, based on the totality of the coating system. Additional conventional matting agents can also be metered into the coating systems.
