The present invention relates to a composition comprising (A) an isocyanate of formula (I) OCN-A-SiR
1
R
2
R
3
(I), wherein A is straight-chain, branched, substituted and/or unsubstituted aliphatic hydrocarbyl of 1 to 12 carbon atoms or substituted or unsubstituted cycloaliphatic hydrocarbyl of 4 to 18 carbon atoms, wherein R
1
is selected from the group comprising —O—R
alk
, wherein R
2
and R
3
are each independently selected from the group of substituents comprising —R
alk
and —O—R
alk
, and wherein —R
alk
is hydrocarbyl of 1 to 6 carbon atoms, and B) a Bronstedt or Lewis acid or a compound which releases a Bronstedt or Lewis acid at room temperature; and also to a process for producing a stabilized alkoxysilane-containing isocyanate comprising the step of adding a Lewis or Bronstedt acid or a compound which releases a Bronstedt or Lewis acid at room temperature to an alkoxysilane-containing isocyanate.
本发明涉及一种组合物,包括(A)式(I)OCN-A-SiR1R2R3(I)的异氰酸酯,其中A是1至12个碳原子的直链、支链、取代和/或未取代的脂肪烃基或4至18个碳原子的取代或未取代的环脂肪烃基,其中R1选自包括-O-Ralk的基团,其中R2和R3各自独立地选自包括-Ralk和-O-Ralk的取代基团的群,其中-Ralk是1至6个碳原子的烃基,以及(B)布朗斯特或路易斯酸或在室温下释放布朗斯特或路易斯酸的化合物;还涉及一种生产稳定的含烷氧基硅烷的异氰酸酯的方法,该方法包括向含烷氧基硅烷的异氰酸酯中加入路易斯或布朗斯特酸或在室温下释放布朗斯特或路易斯酸的化合物的步骤。
