A composition comprising: (a) 1 to 30% by weight of at least one hydrogen phosphate selected from the group consisting of mono- and dihydrogen phosphates of sodium, potassium, ammonium, magnesium, calcium, aluminum zinc, iron, cobalt and copper, optionally in combination with aqueous phosphoric acid 1 to 90% by weight; (b) 1 to 40% by weight of at least one compound selected from the group consisting of oxides, hydroxides and oxyhydates of magnesium, calcium, iron, zinc and copper; (c) 40 to 95% by weight of at least one particulate filler selected from the group consisting of glass, magnesium, calcium, barium and aluminum mono-, oligo- and polyphosphates, calcium, barium sulfate, simple and complex silicates including sodium, potassium, calcium, aluminum, magnesium, iron and / or zirconium, simple and complex aluminates including sodium, potassium, calcium, magnesium and / or zirconium, simple and complex titanates including sodium, potassium, calcium, aluminum, magnesium, barium and / or zirconium, simple and complex zirconates including sodium , potassium, calcium, aluminum and / or magnesium, zirconium dioxide, titanium dioxide, aluminum oxide, silicon dioxide, silicon carbide, aluminum nitride boron nitride and silicon nitride; and (d) 0 to 25% by weight of at least one component different from the components (a) to (c). Component (a) may comprise up to 10% by weight of free water, referred to component (a) in its entirety, component (d) may comprise up to 10% by weight of water, referred to component (d) in its entirety, the composition is in the form of a two or more component system, and the components (a) and (b) are at least substantially separate from one another, or, are separated from each other in the case where component (a) comprises phosphoric acid. |
