  • Q At what pH does the silane coupling agent hydrolyze most slowly?

    A In general, silane coupling agents hydrolyze most slowly in water with pH equal to 7, that is, in neutral water. Acid or Alkali can accelerate the hydrolysis of silane obviously, so the pH of non-amino silane hydrolysis should be adjusted to 3 -5. And the solution of amino silane already has strong alkalinity, so the hydrolysis of most amino silane directly use neutral water on the line.
