Abstract:
1. A process for producing an artificial stone composite, comprising mixing an inorganic component comprising 10-40% by weight of particles having a size of <0.1 mm, 10-40% by weight of particles having a size of 0.1-0.6 mm, 1-80% by weight of particles having a size of 0.61-1.2 mm and 10-50% by weight of particles having a size of 1.21-15 mm, wherein the inorganic powder comprises at least 90% of the composite, with at least one organic polymer binder and simultaneously or subsequently mixing with a mixture comprising (A) at least one silane adhesion promoter of the formula (1) in which R R R w is 0 or 1, x is 0 or 1, y is 0 or 1 and z is 0, 1 or 2, with the proviso that w and x must not both simultaneously be 1, and one or more organosilicon compounds (B), (C), and (D): (B) siloxanes comprising in which R R (C) organosilicon compounds comprising in which R (D) organosilanes of the formula (10) in which R
