Beschreibung
Zusammenfassung:	The present application discloses an acidic-stabilised alkyl silicate composition comprising 0.5-30% by solids volume of inorganic fibres, wherein the fibres have (i) an average length of 25-250 μm and an average thickness of 1-50 μm, and a ratio between the average length and the average thickness (aspect ratio) of at least 5; and (ii) a specific surface area (BET) of 0.01-6 m2/g. A corresponding acidic-stabilised alkyl silicate composition comprising zinc and inorganic fibres, wherein the zinc constitutes 50-95% by solids weight of the total composition, and the fibres constitutes 0.5-30% by solids volume of the non-zinc fraction of the composition, is also disclosed. The application further discloses a method for the establishment of a crack resistant alkyl silicate paint coat by applying one of the compositions to a metal surface.
