用于涂料的疏水剂
摘要：
本发明涉及通式(I)MmDnToQp(I)的有机硅氧烷与通式(II)(A-B)qC(II)的环氧化物的混合物，其中M代表通式(Ia)R1R2R3SiO1/2(Ia)的端基，D代表通式(Ib)R4R5SiO2/2(Ib)的双官能基团，T代表通式(Ic)R6SiO3/2(Ic)的三官能基团，并且Q代表通式为SiO4/2的单元，其中至少一个烃基R6含有至少一个胺官能团并且所有基团中最多75％为羟基或烷氧基，条件是通式(II)的化合物含有至少一个环氧官能团，其中R1、R2、R3、R4、R5、R6、A、B、C、m、n、o、p和q具有在权利要求1中所规定的含义。本发明还涉及通式(I)的有机硅氧烷与通式(II)的环氧化物的混合物作为用于耐候性油漆和涂料的疏水化添加剂的用途；以及涉及含有通式(I)的有机硅氧烷与通式(II)的环氧化物的混合物的耐候性油漆和涂料。
摘要（英）：

The invention relates to mixtures of organosiloxanes of general formula (I) MmDnToQp (I), wherein M stands for a terminal group of general formula (Ia) R1R2R3SiO1/2 (Ia), D stands for a difunctional group of general formula (Ib) R4R5SiO2/2 (Ib), T stands for a trifunctional group of general formula (Ic) R6SiO3/2 (Ic), and Q stands for a unit of general formula SiO4/2, wherein at least one hydrocarbon group R6 contains at least one amine function and at most 75% of all groups are hydroxy or alkoxy groups, with epoxides of general formula (II) (A-B)qC (II), with the proviso that the compound of general formula (II) contains at least one epoxy function, wherein R1, R2, R3, R4, R5, R6, A, B, C, m, n, o, p, and q have the meanings specified in claim 1. The invention further relates to the use of the mixtures of organosiloxanes of general formula (I) with epoxides of general formula (II) as hydrophobing additives for weather-resistant paints and coatings, and to weather-resistant paints and coatings containing the mixtures of organosiloxanes of general formula (I) with epoxides of general formula (II).
