Abstract

A composition that includes an amino-functional compound having at least one silane group, a fluorinated compound represented by formula Rf{—X—[Si(Y)3-x(R)x]y}z, and a non-fluorinated organic solvent having a flashpoint of at least 40° C. A method of making a treated article having a metal surface using a composition that includes an amino-functional compound having at least one silane group, a fluorinated compound represented by formula Rf{—X—[Si(Y)3-x(R)x]y}z, and an organic solvent having a flashpoint of at least 40° C. is also disclosed. Another method includes treating the metal surface with a primer composition including an amino-functional compound having at least one silane group to provide a primed metal surface and subsequently treating the primed metal surface with a treatment composition including a fluorinated compound represented by formula Rf{—X—[Si(Y)3-x(R)x]y}z. The compositions each include up to one percent by weight of an organic solvent having a flashpoint up to 40° C.
