Beschreibung
Zusammenfassung:	An isocyanate-functional prepolymer comprises the reaction product of: (A) a polyol; (B) an organopolysiloxane having at least two carbinol-functional groups per molecule; and (C) a polyisocyanate. Components (A) to (C) are utilized to provide a stoichiometric excess of isocyanate-functional groups in component (C) over the total amount of isocyanate-reactive groups of components (A) and (B). An isocyanate component comprising the isocyanate-functional prepolymer is also disclosed. The isocyanate component also comprises (E) a filler. In addition, a composition is disclosed, which comprises the isocyanate component and an isocyanate-reactive component. Further, a method of preparing a coating with the composition is disclosed, which method comprises applying the composition on a substrate and forming the coating from the composition on the substrate. A coated substrate comprising the substrate and a coating disposed on the substrate, the coating being formed from the composition, is additionally disclosed.
