The particular advantages of the curing component proposed in accordance with the invention, such as effective producibility, high environmental friendliness, and excellent storage stability of the resin/curing agent mixtures, make these azetidine derivatives outstandingly suitable for one-component, moisture-hardening polymer compositions, which are of special interest in particular for the production of (floor) coatings, sealants, and adhesives.

The binder component consists essentially of urethane dispersions with defined structural components which, in turn, consist of special reaction products. Such polyurethane resins are used for the production of fluorine-modified polyurethane coatings and generally in construction or industrial applications for the permanent oil-, water- and dirt-resistant coating of mineral and non-mineral surfaces on the basis of, for example, hydraulically setting components.

At a simultaneously reduced fluorine content, these compositions have considerably improved application properties and, in combination with suitable stabilizing components and hydrophilic silane components, they exhibit excellent hydrophobic, oleophobic and soil-repellent properties, having overall excellent storage stability.

Abstract: An aqueous fluoromodified polyurethane system for one- or two-component anti-graffiti and anti-soiling coatings is prepared by (a) preparing a binder component based on an aqueous solution or dispersion of optionally hydroxy- and/or amino-functional oligourethanes and/or polyurethanes having fluorinated side chains, and, optionally, (b) subsequently reacting the binder component with a crosslinker.

Abstract: A fluoromodified admixture containing isocyanate and urethane and/or urea groups is described. Surprisingly, it has been found that the fluoromodified admixture according to the invention is outstandingly suitable even at a very low dosage for the permanent hydrophobic and/or oleophobic and/or dirt-repellent in-bulk finishing of products based on inorganic or hydraulic or mineral binders, without the fundamental property profile (e.g. compressive and flexural tensile strengths) of these products being substantially influenced. Moreover, it was not to be foreseen that in the case of the products treated with the fluoromodified admixtures according to the invention (e.g. hardened building material compositions) a markedly lower water absorption (avoidance of frost damage and corrosion) and a suppression of bleeding on the surfaces (avoidance of visual impairment) are to be observed. Furthermore, it could not be expected that in spite of the high fluorine modification an adequate self-dispersibility is afforded.
