Abstract

A method of making a powder coating composition includes obtaining functionalized particles by reacting inorganic particles with alkoxysilanes having the general structural formula (I) R1Si(OR2)3, silane oligomers having the general structural formula (II) (R1)(OR2)2Si—O—[—Si(R1)(OR2)—O—]m−—Si(R1)(OR2)2 or mixtures thereof.
