Abstract:
1. A single component RTV-1 crosslinkable moisture-curable organosilicon composition prepared by admixing components comprising: (A) 100 parts by weight of at least one organosilicon compound (2) of the formula (III) where c is 0, 1, or 2, R Y may be identical or different and is a hydroxy group or a hydrolyzable radical, and d is a whole number from 200 to 10,000, and optionally one or more organopolysiloxanes different from (III) having at least two hydroxyl groups or at least two hydrolyzable radicals, (B) from 0.1 to 15 parts by weight, based on the total weight of the composition, of at least one organosilicon compound (1) of the formula (I) where R each is identical or different and is a monovalent, optionally substituted hydrocarbon radical optionally interrupted by heteroatoms, a is 0 or 1, and b is 0, 1, 2 or 3, with the proviso that the organosilicon compound has one and only one unit of the formula (I) where a=1, and has a viscosity of from 5 to 1000 mPas at 25° C., (C) one or more silane crosslinking agents (3) or a partial hydrolysis product thereof, said silane crosslinking agents selected from the group consisting of tetraethoxysilane, tetraisopropoxysilane, tetra-n-propoxysilane, methyltrimethoxysilane, methyltriethoxysilane, vinyltrimethoxysilane, vinyltriethoxysilane, acetoxysilanes, and oximinosilanes, (D) optionally one or more condensation catalysts, (E) one or more plasticizers in an amount of from 10 to 300 parts by weight based on 100 parts by weight of organosilicon compound (2), (F) optionally, one or more fillers in an amount of 0 to 300 parts by weight based on the weight of (A), (G) optionally, one or more adhesion promoters, and (H) optionally one or more further additives selected from the group consisting of pigments, dyes, odorants, oxidation inhibitors, agents for influencing electrical properties, flame retardants, light stabilizers, skinning time lengthening agents, cell forming agents, heat stabilizers, thixotropic agents, and organic solvents.
