<p>Modified silicate, obtained by reacting an aqueous solution of silicate compound (a) with at least one silane compound (b) at 5-100[deg] C, is new. Modified silicate, obtained by reacting an aqueous solution of silicate compound of formula (M 2O.nSiO 2) (a) with at least one silane compound of formula (R-(CH 2) n-Si-X 3) (b) at 5-100[deg] C, is new. M : cation such as Li +>, Na +>, K +>or NY1 4+>; Y1 : H, 1-22C alkyl or 1-22C alkenyl; X : CH 3, OCH 3, OC 2H 5, OC 3H 7, OCOH 3or Cl; R : optionally saturated, at least 2C-cyclic radical having at least one O and/or N; and n : 1-3. An independent claim is included for an aqueous agent comprising the modified silicate containing 10-90 (preferably 35-75) wt.% of the active substance.</p> |
