Summary

There are two hot topics in the field of building protection today: protection against ingress of water, and protection against all kinds of soiling, especially graffiti. Fluoroalkyl-modified silanes produce excellent hydro- and oleophobic effects on a large variety of surfaces. Our first fluoroalkyl silane product, Dynasylan® F 8261 was introduced commercially in 1997. Since then we have developed new water-based fluoroalkylsilane systems which generate invisible, weather-resistant and gas-permeable coatings on porous mineral surfaces: Dynasylan° F 8800 and Protectosil° Antigraffiti. The application fields include easy-to-clean surfaces and permanent anti-graffiti coatings with excellent cleaning properties. The combined application of alkylsilanes with water-borne fluoroalkylsilane systems offers exellent protection against both water ingress and surface soiling.
