    摘要： The present invention relates to a two-component putty comprising (1) a base component and (2) a curing component, wherein the base component comprises:— a polycarbonate diol having a hydroxyl number in the range of from 50 to 500 mg KOH/g;— a further resin component having a hydroxyl number of at least 300 mg KOH/g; and— an inorganic filler, wherein the curing component comprises a polyisocyanate, and wherein the amount of the inorganic filler is in the range of from 35 wt % to 60 wt %, based on the total weight of the putty, the putty contains less than 5 wt % of organic solvent, and the viscosity of the putty is in the range of from 30,000 mPa·s to 250,000 mPa·s. The present invention also relates to a method for coating a substrate by applying such putty and allowing the applied putty to cure. The invention further relates to a coated substrate obtainable by such method and the use of such two-component putty for improving erosion resistance of a substrate.
