Various embodiments disclosed relate to a resin including nanoparticles including surface-bonded hydrophobically-modifying alkyl groups. The present invention provides a resin component that includes a curable resin. The resin component also includes nanoparticles dispersed in the resin. The nanoparticles each independently include surface-bonded hydrophobically-modifying (C1-C50)hydrocarbyl groups. At least one of the (C1-C50)hydrocarbyl groups is a (C1-C50)alkyl group and at least one of the surface-bonded hydrophobically-modifying (C1-C50)hydrocarbyl groups is a (C6-C50)aryl group.
