摘要:
The invention concerns a coating material containing: A) at least one type of hydrophobic silicon dioxide nanoparticles, and B) at least one type of hydrophilic silicon dioxide nanoparticles, with an inner BET surface area > 300 m2/g. The invention also concerns a method for producing said material and use thereof.
摘要:
The invention relates to a cathodic electrodeposition coating which contains at least one binder, at least one cross-linker and at least one bismuth compound, characterized in that a basic bismuth nitrate is used as the bismuth compound and polymethylene urea is contained as an additional component.

The invention relates to a method for producing molded parts, according to which a pigmented coating agent (P) and a radically cross-linkable coating agent (K), which after final cross-linking produces a transparent coating (KE), are applied to a support film, the coating agent (K) is used to produce a dried but not finally cross-linked coating(KT), the coated support film is shaped and back-injected or back-foamed with a liquid plastic material, and the coating (KT) is allowed to cure or post-cure unless it has already done so. The cross-linkable coating agent (K) comprises a radically cross-linkable component (KK) which has H-bridging structure elements in such an amount that 1) a not finally cross-linked coating (MT) produced from the mixture (M) of component (KK) with additives has a ratio of storage modulus G(MT)' to loss modulus G(MT)' of 5 to 200, G(MT)' and G(MT)' being determined at 20 °C by rheological oscillation measurements, and 2) a finally cross-linked coating (ME) produced from the mixture (M) of component (KK) with additives has a storage modulus E(ME)' of 1.0 * 107.0 to 8.0 * 107.0 Pa, whereby E(ME)' is measured by dynamic mechanical thermal analysis in the rubber-elastic range.

The invention relates to a cathodic electrodeposition paint, containing (A) at least one organic binder, which can be dispersed in water and contains cationic groups, wherein 0.005 - 0.5 wt.-%, relative to the solid content of said cathodic electrodeposition paint, (B) of an organic, tetravalent titanium, zirconium, or hafnium complex having one or more ligands containing oxygen was added to said cathodic electrodeposition paint.
