Definitions
- rock-impact-resistant coatings on metallic substrates is of particular importance in the field of motor vehicle manufacturing. A number of requirements are placed on a filler or a rockfall protection ground.
- the surfacer layer is said to have a high stone chip resistance, in particular to Multish, and at the same time good adhesion to the primer, in particular to cathodic electrocoat and basecoat, good filling properties (covering the structure of the substrate) at layer thicknesses of about 20 to 35 ⁇ m and cause a good Appearance in the final clearcoat.
- suitable coating materials especially for ecological reasons, preferably be poor or largely free of organic solvents.
- Coating compositions for fillers are known and described for example in EP-A-0 788 523 and EP-A-1 192 200. There, water-dilutable polyurethanes are described as binders for fillers, which are intended to ensure the stone chip resistance, in particular with comparatively low layer thicknesses.
- binders for fillers which are intended to ensure the stone chip resistance, in particular with comparatively low layer thicknesses.
- KTL-filler basecoat clearcoat When loaded in stone impact tests occur in the fillers of the prior art used in automotive OEM OEM coating structures (KTL-filler basecoat clearcoat) despite good stone chip resistance, ie a relatively small number of damage, but often damage patterns on the paint layer in which the unprotected metal substrate is exposed by uncontrolled crack propagation in the OEM layer structure and subsequent delamination at the interface between metal and KTL.
- WO-A-01/04050 discloses inorganic anionic or cationic layer fillers for aqueous coating compositions having good barrier properties, which are modified with organic compounds for widening the spacing of the layers in the filler, which have at least two ionic groups are separated by at least 4 atoms.

- the coating compositions described in WO-A-01/04050 are only conditionally suitable for use in OEM layer structures, since the organic modifiers in the applied layer produce a high local density of charges due to the multiple charge, which macroscopically increases Hygroscopy of the cured layer leads, which in particular has negative consequences for the condensation resistance of the layer.
