Curable compositions are provided comprising: (a) an isocyanate-functional prepolymer having a weight average molecular weight of 4000 to 15,000; (b) a curing agent comprising a mixture of polyamines, wherein at least one polyamine has an amine equivalent weight of 125 to 250; and (c) an abrasion resistant additive comprising organic and inorganic particles. The isocyanate-functional prepolymer is (i) a reaction product of a polyisocyanate and a polyamine having primary and/or secondary amino groups; and/or (ii) a reaction product of a polyisocyanate and a polyol. Upon application of the composition to a substrate as a coating and after curing to form a coated substrate, the coated substrate demonstrates a coating loss of less than 0.33 cm3 after being subjected to 1000 cycles of a TABER Abrasion Test using S-42 sandpaper strips and two 1000 gram weights. Coated substrates and footwear components prepared from the compositions are also disclosed.
