Patent ID: 7491786

Claim:
A condensation crosslinkable composition based on organosilicon compounds, comprising (a) at least one polymer of the formula X n R 3-n Si-A-SiR 2 —(CH 2 ) 3 NHY (I) where n is 1 or 2, X each is the same or different and is a hydroxyl radical or hydrolyzable radical, R each is the same or different and is a monovalent, optionally substituted hydrocarbon radical, Y each is the same or different and is a hydrogen atom or a —Si(CH 3 ) 2 (CH 2 ) 3 NH 2 radical, and A each is the same or different and is a divalent organic or organosilicon radical, (b) at least one polymer of the structure X 1 k R 5 3-k Si-A 1 -SiX 1 k R 5 3-k (II) where k each is the same or different and is 1 or 2, R 5 each is the same or different and has the definition specified for R, A 1 each is the same or different and has the definition specified for A, and X 1 each is the same or different and has the definition specified for X, (c) one or more silanes of the formula R 6 m SiX 2 4-m (III) and/or partial hydrolyzates thereof, where m is 0 or 1, R 6 each is the same or different and has the definition specified for R and X 2 each is the same or different and has the definition specified for X, and (d) optionally, one or more silanes of the formula R 4 o SiR 7 p X 3 4-o-p (IV) and/or partial hydrolyzates thereof, where p is 0 or 1, o is 1 or 2, R 7 each is the same or different and has the definition specified for R, X 3 each is the same or different and has the definition specified for X, and R 4 each is the same or different and is a monovalent, SiC-bonded hydrocarbon radical substituted by nitrogen, oxygen, sulfur and/or halogen, with the proviso that the sum of o+p is less than 3.
