Abstract (en)
[origin: WO2007104494A1] A fluorine-modified additive having a content of isocyanate and also urethane and/or urea groups is described. It has been found that, surprisingly, the inventive fluorine-modified additive, even at very low dosage, is outstandingly suitable for permanent hydrophobic and/or oleophobic and/or soil-repellent in-bulk modification of products based on inorganic or hydraulic or mineral binders, without significantly influencing the fundamental property profile (for example compressive and flexural strengths) of these products. In addition, it was not foreseeable that, in the products treated with the inventive fluorine-modified additives (for example hardened building materials), a significantly lower water absorption (prevention of frost damage and corrosion) and suppression of blooms on the surface (prevention of visual impairments) are observed. Moreover, it could not have been expected that, in spite of the high fluorine modification, there is sufficient self-dispersibility.
