Definitions
- the invention relates to coating compositions based on crosslinkable compositions comprising silane-crosslinking prepolymers, silicone resins and fillers, processes for their preparation and their use for coating, in particular of floors.
- Floors typically consist of a successive unit of substrate and wear layer.
- the subsurface is composed of a supporting layer, which is usually made of concrete, and optionally of an intermediate layer located thereon.
- the latter is usually screed or mastic asphalt. It serves to level the ground or to reduce a gradient. In pure industrial floors is often dispensed with an intermediate layer.
- the actual surface wearing course is applied to this substrate. It serves to protect the substrate against physical wear and also against chemical stress. At the same time, it must meet the optical requirements of the floor coating.
- epoxy resin systems are often too hard and brittle and have very poor adhesion properties, especially on moist substrates.
- Polyurethane systems tend to be moist on grounds of carbon dioxide release during the reaction of isocyanate groups with water to bubble.
- silane-crosslinking coatings which cure by the condensation reactions of alkoxysilyl groups would be extremely desirable. This reaction occurs on contact with atmospheric moisture, which is why such systems are usually one-component processable.
- the silyl groups can also react with a variety of reactive OH groups of the substrate, which is why the corresponding products often have remarkably good adhesion properties.
- silane-terminated prepolymers which have reactive alkoxysilyl groups which are connected by a methylene spacer to an adjacent urethane unit.
- This class of compounds is highly reactive and requires neither tin catalysts nor strong acids or bases in order to achieve high curing rates when exposed to air.

- steel punches with a square base with an edge length of 5 cm and a thickness of 1 cm with a quick adhesive (Fa. Delo, type Automix AD895; 2K epoxy resin adhesive) glued.
- the coating is cut at the stamp edges to the underlying concrete.
- the punches are peeled off with an HP 850 tensile tester from Herion, the tensile force starting at 0 N and increasing at a constant rate of 100 N / s until the tearing off takes place.
- Each adhesion measurement is performed four times and the results are averaged. These averages include Stan ⁇ deviation can be found in Table 2 below.
- the ready-to-use mass is applied by hand with a spatula in a layer thickness of about 3 mm on concrete terrace slabs with a thickness of about 3, 7 cm, on which a primer was previously applied with a brush, with a quantity of about 100 g Primer per m 2 was applied.
- the Ap- Plication of the coating then takes place wet in wet directly after application of the respective primer.
- compositions described in Examples 11 to 14 are self-leveling, i. form a smooth surface after application on a horizontal surface. The application is done by simply pouring.
