| abstract |
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. |
