The present disclosure relates to a two-component, solvent-based coating composition comprising i) a base component comprising one or more polyesterdiols with a hydroxyl value in the range of from 150 to 500 mg KOH/g and one or more organosilane-modified inorganic fillers, and ii) a polyisocyanate curing component. Said composition can be formulated such that it has a viscosity suitable for spray application (low viscosity under high shear rate) and yield coatings with very good erosion resistance. The present disclosure further relates to a method for coating a substrate using said two-component coating composition, to a coated substrate obtainable by such method, and to use of such coating composition for improving erosion resistance of a substrate.
