Problems solved by technology

[0006] However, at least some coatings prepared using these compositions and methods can form corrosion and / or pits on the surface
In addition, at least some conversion compositions known in the art can also suffer from one or more of the following disadvantages: (1) a tendency for ingredients to precipitate in solution, leaving the metal surface as a slurry-like material; (2) difficulty Obtain a uniform coating that has no tendency to over-coat and exhibits poor adhesion to the substrate; (3) must use multiple steps and long periods of time to deposit the coating; and (4) must use Special pretreatment and solution compositions to coat multilayer alloys, especially aluminum 2024 alloy

Embodiment 1

[0201] Three aluminum 2024T3 bare substrates (Priority Metals, Orange County, CA), each measuring 3" x 10" x 0.032", were hand wiped with methyl ethyl ketone (100%) and a disposable cloth, and air dried, This was followed by chemical cleaning. Each plate was immersed in a bath containing SOCOCLEAN A3432 (a commercially available cleaning composition from Socomore, prepared according to the manufacturer's instructions) for 10 minutes at 55° C. under agitation. Then rinse with deionized water Each panel was spray rinsed for 30 seconds, followed immediately by immersion in deionized water rinse for 2 minutes. After immersion rinse, each panel was immersed in SOCOSURF Al858-Al806 containing SOCOSURF Al858-Al806 (commercially available from Socomore) with agitation. agent, prepared according to the manufacturer's instructions) for 5 minutes. Each panel was then spray rinsed with deionized water for 30 seconds and immediately immersed in a deionized water rinse for 2 minutes. After t...

Abstract

Disclosed is a conversion composition containing a trivalent chromium cation in an amount of 0.001 g / L to 20 g / L. Also disclosed is a system for treating a metal substrate that includes the conversioncomposition and a sealing composition comprising a lithium cation. Also disclosed is a method for treating a metal substrate that includes contacting at least a portion of a surface of the substratewith the conversion composition and then contacting at least a portion of the surface of the substrate with the sealing composition. Also disclosed is a substrate obtainable by treatment with the system and / or obtainable by the method of treating.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Application No. 62 / 374,188, filed August 12, 2016, titled "Sealing Composition," and U.S. Provisional Application No. 62 / 374,188, filed December 8, 2016, titled "System for Treating a Substrate," Priority of .62 / 431,454, both of which are hereby incorporated by reference in their entirety. [0003] field [0004] The present invention relates to compositions, systems and methods for treating substrates. The invention also relates to substrates obtainable by treating with such systems and methods. Background of the invention [0005] Oxidation and degradation of metals used in aerospace, commercial and private industry is a serious and costly problem. To prevent oxidation and degradation of the metals used in these applications, inorganic protective coatings can be applied to the metal surfaces. This inorganic protective coating, also known as a conversion coating, can be the o...
