Abstract

An artificial stone can be prepared by binding a suitable stone filler with a binder which contains a silicon bonded, hydroxyl-functional silicone resin also optionally bearing silicon bonded alkoxy groups, and an organosilicon compound which is a silane or siloxane bearing silicon bonded alkoxy groups. The artificial stone is resistant to the effects of UV light as well as heat.
