Impregnating agents for natural and artificial stone

The Silsan® FC product line from Graf Chemie offers advanced impregnating agents based on modern, PFOA- and PFOS-free C6 fluorine compounds combined with silanes and siloxanes. These formulations provide not only long-lasting water repellency but also resistance against oil, grease, food stains, and dirt – making them ideal for demanding applications in kitchens, high-traffic floors, garages, and façades.

Silsan® FC agents penetrate deeply into mineral substrates, preserving full vapor permeability while forming an invisible protective barrier. Depending on the variant, they can either enhance the natural color intensity of the treated surface or leave it unchanged, ensuring flexibility in aesthetic requirements. Available as both water-based and solvent-based concentrates, they are diluted prior to use and offer reliable, long-term protection even under extreme weather conditions.

Typical applications include the impregnation of marble, granite, cotto, travertine, bricks, clinker, and other natural or artificial stones. They are equally effective for worktops, kitchen surfaces, façades, and exterior walls, providing a complete all-round protection that combines durability, easy maintenance, and preserved appearance.
