Patent ID: 7419564

Claim:
A binder composition for providing barrier properties comprising: a) a compound containing at least one NCO group and at least one radiation-curable reactive functional group, as component (A), and b) an organosilicon compound as component (B), wherein component (B) is a reaction product of at least one polyisocyanate with at least one organosilicon compound of the formula (III): provided that the reaction product in component (B) contains at least one NCO group: Y 1 —A—Si(Z) n (X) 3−n (III); wherein: Y 1 =—OH, —COOH, —SH, —NH 2 , NHR″ group; R″=linear or branched, saturated or unsaturated C 1 -C 18 alkyl; C 5 -C 8 cycloalkyl, C6-C 10 aryl, C 7 -C 12 aralkyl radical; oxyalkylene radical having up to 4 carbon atoms, A—Si((Z) n )(X) 3−n ; an alkyl-, cycloalkyl- or aryl-substituted siloxane radical containing about 1 to about 20 silicon atoms; A=a linear or branched, saturated or unsaturated alkylene group having 1 to 12 carbon atoms; Z=a C 1 -C 18 alkyl group; X=—NH 2 ; —NH—CO—R; —OOC—R; —O—N═C(R) 2 or OR′; R=a linear or branched, saturated or unsaturated C 1 -C 18 alkyl radical; R′=R; or an (oxyalkylene) m radical wherein the oxyalkylene has up to 4 carbon atoms; a C 5 -C 8 cycloalkyl radical; a C 6 -C 10 aryl radical or a C 7 -C 12 aralkyl radical; m=1 to 40; and n=0, 1, or 2.
