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.
Claims13
A method of producing functionalized particles by reacting inorganic particles with a silane oligomer having the general structural formula (II)
- (R1)(OR2)2Si—O—[—Si(R1)(OR2)—O—]m−—Si(R1)(OR2)2
- or mixtures thereof, and
- If necessary, subjecting a resulting reaction mixture to drying,
- wherein:
- R1 is a nonhydrolyzable, aliphatic, straight-chain or branched-chain hydrocarbon radical having 1 to 18 carbon atoms, with —O— in the chain, having at least one functional group which is able to enter in an addition reaction or condensation reaction, and wherein said at least one functional group of R1 is selected from the group consisting of amino, epoxy, vinyl, and methacrylate,
- R2 is H or a hydrolysable group, and
- m=0-10.
