摘要:
The invention relates to binder-free spot blender compositions for one- and two-component clearcoat materials comprising at least one isocyanate compound, to processes for producing them, and to their use in automotive refinish.
摘要:
A UV-A-curable, solvent-containing composition composed of (A) 1% to 50% by weight of a UV-A-curable constituent containing isocyanate-reactive groups; (B) 0.01% to 10% by weight of a colorless photoinitiator having an absorption maximum in the wavelength range of λ=300 to 400 nm; (C) 10% to 70% by weight of an alkyl and/or cycloalkyl acetate having 3 to 10 carbon atoms in the alkyl radical and/or in the cycloalkyl radical; (D) 10% to 70% by weight of an alkoxyalkyl, alkoxycycloalkyl, cycloalkoxyalkyl and/or cycloalkoxycycloalkyl acetate; (E) 0.01% to 5% by weight of a constituent that lowers the interfacial tension; (F) 0 to 50% by weight of an alkylaromatic having at least two alkyl radicals having 1 to 6 carbon atoms in the molecule; and (G) 0 to 50% by weight of an additive different from constituents (A) to (F); processes for preparing it, and its use as a spot blender in automotive refinishing, especially in spot repair, or for preparation thereof.
摘要:
An integrated coating material system comprising (I) at least one solventborne coating material system which is free from hiding pigments and is curable thermally or both thermally and with UV-A radiation and comprises (I.1) at least one separate component which is free from isocyanate groups and contains isocyanate-reactive functional groups, and (I.2) at least one separate component which is free from isocyanate-reactive functional groups and contains isocyanate groups, none of components (I.1) and (I.2) or at least one of components (I.1) and/or (I.2) containing at least one UV-A-curable constituent; and (II) at least one separate, UV-A-curable coating material which is free from hiding pigments and isocyanate groups and contains solvent and isocyanate-reactive functional groups; the UV-A-curable constituents being present in combination with at least one colorless or substantially colorless photoinitiator having at least one absorption maximum in the wavelength range of λ=300 to 400 nm; process for producing it, and use thereof.
