International Classification:

C23F 11/00
C23F 11/18
B32B 5/00

US Classification:

25238954, 252387, 42840224, 428403, 428407

Abstract:

The present invention provides for a slow-release inhibitor that is applied to a metal surface, such as by way of a paint or primer coating, for corrosion control of the metal. An exemplary embodiment of the slow-release corrosion inhibitor includes a water-soluble particle, or pigment, and an organic polymeric film that encapsulates the particle. This water-soluble particle may be either organic or inorganic and, preferably, is non-carcinogenic and non-toxic. An additional water-soluble particle having an encapsulating, organic polymeric film further may be provided along with a water-soluble, organic compound to form the corrosion inhibitor. The polymeric film(s) are of a desired hydrophobicity and permeability to permit, upon interaction of the particle(s) with water, controlled diffusion of particle ions therethrough.

Abstract:

A composition capable of coating a substrate and curing to provide a hydrophobic film inhibiting corrosion, the composition comprising: (a) a bis-silane comprising between about 0.5 weight percent to about 50 weight percent of the composition; and (b) a water soluble or dispersible polymer comprising between 10 weight percent to about 80 weight percent of the composition. A further exemplary superprimer in accordance with the instant invention includes a composition capable of coating a substrate and curing to provide a hydrophobic film inhibiting corrosion, the composition comprising: (a) a mixture of silanes; (b) a dispersible or soluble resin; and (c) an aqueous or non-aqueous solvent. Moreover, the invention includes the aforementioned superprimer composition, wherein the mixture of silanes includes at least one of a bis-sulfur silane, a bis-benzene silane, a bis-alkane silane, a bis-alkene silane, and a bis-amino silane.
