    摘要: A composition which retains a flash point of more than 21° C. even on storage and is obtainable by mixing and reacting (i) from 50 to 70% by weight of at least one alkyltrialkoxysilane, (ii) from 10 to 25% by weight of at least one alkoxysiloxane and/or at least one tetraalkoxysilane, (iii) from 15 to 25% by weight of at least one aqueous silica sol, (iv) from 0.1 to 5% by weight of at least one acid, and (v) from 0.1 to 60% by weight of at least one alcohol and/or glycol, the sum of the above components being not more than 100% by weight, by introducing components (i) and (ii) and also, if desired, a fraction of component (v) as an initial charge, adding component (iii), adjusting the mixture to a temperature in the range from −5 to 10° C., and subsequently adding component (iv), then allowing the mixture to continue reacting, thereafter distilling off hydrolysis alcohol under reduced pressure, and replacing it by adding component (v); which composition is useful for producing a coating on surfaces and also as a base material for paints; a process for preparing such a composition; and coatings and articles obtainable by applying such a composition.

    摘要: The present invention relates to a composition containing silico-organic nanohybrid and/or microhybrid capsules for scratch-resistant and/or abrasion-resistant coatings, wherein the silico-organic nanohybrid and/or microhybrid system includes one or more small metal oxide cores A and a substantially complete, silico-organic shell B, and the composition can be obtained by a reaction performed in situ, in a synthetic resin or in a synthetic-resin precursor compound, between metal oxide particles (KA-O) and at least one organofunctional silicon compound which contains an organofunctional group and at least one hydrolyzable group or at least one hydroxy group. The present invention also relates to the use of such compositions as the base for lacquers for producing a scratch-resistant and abrasion-resistant coating on a substrate as well as articles provided with corresponding scratch-resistant as well as abrasion-resistant coatings.
