Patent ID: 8172936

Claim:
A process for hydrophobizing mineral fiber components, characterized in that, in the production of the mineral fiber components, siloxanes of the general Formula (I) are added M a M′ b D c D′ d D alkoxy e T f Q g (I) in which M=(R 1 3 SiO 1/2 ), M′=(R 1 2 R 2 SiO 1/2 ) D=(R 1 2 SiO 2/2 ), D′=(R 1 R 3 SiO 2/2 ), D alkoxy =(R 1 R 4 SiO 2/2 ), T=(R 1 SiO 3/2 ), Q=(SiO 4/2 ) a=0-22, b=0-22, c=5-400, d=0-20, e=0-40, f=0-10, g=0-10, with the proviso that a+b is greater than or equal to 2 and b+e is greater than or equal to 2, R 1 =identical or different, aliphatic or aromatic hydrocarbon radicals which optionally have ether functions and/or ester functions and optionally carry halogen atoms, R 2 =identical or different radicals from the group R 3 , R 4 , for e less than or equal to 1, R 2 =R 4 , R 3 =identical or different polyether radicals or H, R 4 =identical or different radicals of the general Formula (III) —(CH 2 ) k —Si(R 6 ) l (OR 6 ) 3-l (III) k=2-12, l=0-2, R 6 =identical or different alkyl or aryl radicals.
