Abstract: Adhesion-promoting compositions and the use of the adhesion-promoting compositions to provide adhesion-promoting interlayers to enhance adhesion between adjoining layers of sulfur-containing sealants are disclosed. In repair applications, the adhesion-promoting compositions can enhance the adhesion of an overlying radiation-curable sulfur-containing sealant to a damaged or aged sulfur-containing sealant.

Abstract: A solar reflective coating composition includes: a film-forming resin; a plurality of near-IR transparent pigments dispersed in the film-forming resin, the plurality of near-IR transparent pigments including a first perylene pigment and a second perylene pigment different from the first perylene pigment; and a near-IR reflective pigment dispersed in the film-forming resin, the near-IR reflective pigment different from the first perylene pigment and the second perylene pigment. When formed into a cured coating over a substrate, the cured coating exhibits an off-white or grey color. The solar reflective coating composition is substantially free of carbon black. The present invention is also directed to a substrate having a surface at least partially coated with a solar reflective coating composition and a method of preparing a low weight aerospace component.

Abstract: Coating systems are used to visually hide low-profile surface features and to establish the optical properties of high profile surface features. The coating systems are useful in hiding build lines on the surface of articles fabricated using three-dimensional printing. Using the coating systems, the optical properties of intentional surface features such as patterns and textures can be modified to achieve a desired optical effect.

Abstract: A composition for application to a metal substrate comprises an aqueous carrier, a hydroxide anion and/or a phosphate anion, and a corrosion inhibitor comprising an azole compound, a rare earth ion, an alkali earth metal ion, and/or a transition metal ion. A substrate or article includes the composition for application to a metal substrate and a coating on the composition. A method of fabricating a substrate comprises applying the composition to a substrate, allowing the composition to dry to form a dried composition, and applying a coating on the dried composition.

IPC: C25D5/34

Abstract: Methods for treating a substrate are disclosed. The substrate is deoxidized and then immersed in an electrodepositable pretreatment composition comprising a lanthanide series element and/or a Group IIIB metal, an oxidizing agent, and a metal-complexing agent to deposit a coating from the electrodepositable pretreatment composition onto a surface of the substrate. Optionally, the electrodepositable pretreatment composition may comprise a surfactant. A coating from a spontaneously depositable pretreatment composition comprising a Group IIIB and/or Group IVB metal may be deposited on the substrate surface prior to electrodepositing a coating from the electrodepositable pretreatment composition. Following electrodeposition of the electrodepositable pretreatment composition, the substrate optionally may be contacted with a sealing composition comprising phosphate and a Group IIIB and/or IVB metal. Substrates treated according to the methods also are disclosed.

Abstract: Disclosed is a method of treating a substrate. The surface is contacted with a sealing composition comprising a lithium cation; and optionally, with conversion composition comprising a cation of a lanthanide, a Group IIIB, and/or a Group IVB metal. The conversion composition is applied to provide a film on the substrate surface resulting in a level of the lanthanide, Group IIIB metal, and/or Group IV metal thereon of at least 100 counts greater than on a surface of a substrate that does not have the film thereon as measured by X-ray fluorescence (measured using X-Met 7500, Oxford Instruments; operating parameters 60 second timed assay, 15 Kv, 45 μA, filter 3, T(p)=1.5 μs for lanthanides, Group IIIB metals, and Group IVB metals except zirconium; operating parameters 60 second timed assay, 40 Kv, 10 μA, filter 4, T(p)=1.5 μs for zirconium). A substrate obtainable by the methods also is disclosed.

Abstract: Disclosed is a method of making a treatment composition. A lithium cation and carbon dioxide are combined in an aqueous medium to form the treatment composition comprising lithium carbonate in situ. Also disclosed is a system and method for maintaining a treatment bath formed from a treatment composition comprising lithium carbonate. Carbon dioxide and/or a lithium salt are supplied to the bath in an amount sufficient to maintain the pH of the treatment bath at 9.5 to 12.5, lithium in an amount of 5 ppm to 5,500 ppm (calculated as lithium cation) and carbonate in an amount of 15 ppm to 25,000 ppm (calculated as carbonate) based on total weight of the treatment bath. Substrates treated with the composition, system and method also are disclosed.
