摘要:
Process for the production on metal or plastic surfaces of thin, hydrolysis-resistant, scratch-resistant and stain-resistant coatings, wherein the coating material can be applied directly to the cleaned metal surface and subsequently cross-linked by high-energy radiation, in particular UV radiation. The substrates can be coated in the form of strip and only subsequently brought into the required external shape. Coated substrates such as these are no longer susceptible to staining by food, cleaning agents or fingerprints and can also be rendered antibacterial. Objects coated in this manner are thus suitable for use in architecture, for interior fittings of buildings, in furniture-making as well as for ornamental applications, and in particular in households, in sanitary applications, in hospitals and in the food-processing and pharmaceutical industries.

摘要:
A chromium-free corrosion inhibitor containing at least one titanium, silicon and/or zirconium compound corresponding to general formula (I): in which Me is a titanium, silicon or zirconium ion, at least one other olefinically unsaturated comonomer containing at least two olefinically unsaturated double bonds per molecule, optionally other comonomers containing one olefinically unsaturated double bond per molecule, and at least one radical and/or cationic polymerization initiator that is activated by radiation.
摘要:
The invention relates to a method and coating agents used in the method which provide good adherence to and good corrosion protection of metal substrates; the coating coating agents are cross-linkable via radical polymerization. Adhesion promoting compounds are present in the conversion layer in a quantity of about 0.01 to 40 weight percent and contain, on average, one reactive unsaturated group and at least one H-active group per molecule.
