A corrosion-resistant coating on an aluminum-containing substrate such as an aluminum substrate, an aluminum alloy substrate (e.g., AA 2024, AA 6061, or AA7075), or other aluminum-containing substrate includes a corrosion inhibitor-incorporated ZnAl layered double hydroxide (LDH) layer and a sol-gel layer. A zinc salt and a corrosion inhibitor (e.g., a salt of an oxyanion of a transition metal such as a vanadate) is dissolved to form a zinc-corrosion inhibitor solution, and the substrate is immersed in or otherwise contacted with the solution to form the corrosion inhibitor-incorporated ZnAl LDH layer on the substrate. A sol-gel composition is applied on the corrosion inhibitor-incorporated ZnAl LDH layer of the substrate to form a sol-gel layer, and the sol-gel layer is cured.

The present invention concerns anti-corrosive coating compositions, in particular coating compositions for protecting iron and steel structures. In particular, the present invention relates to silicate-based coating compositions comprising particulate zinc, conductive pigments, and glass hollow microspheres. The invention furthermore concerns a kit of parts containing the composition, a method for its application, as well as metal structures coated with the composition.

The composition described herein for the prevention of corrosion comprises: sacrificial metal particles more noble than a metal substrate to which the composition contacts; carbonaceous material that can form electrical contact between the sacrificial metal particles; and means for providing an anticorrosion coating material for the metal substrate. The composition can form a coating on a metal substrate surface. A method for applying the composition for the prevention of corrosion is also described herein.

The present invention is directed to a specific class on pigment reactive silicone polymers that contain both higher alkyl groups and reactive trialkoxy silanes present in the backbone of a specific silicone polymer. By carefully selecting the proper reactive silicone polymer and treating the pigment with said polymer a surprisingly stable and efficient coating is applied the pigment, most importantly ZnO and TiO.sub.2 as to render photo stability and alter solubility of the pigment in a variety of solvents.

A semifinished product is disclosed and includes a high-quality, weather-resistant coating. Also disclosed is a method for manufacturing the semifinished product and the use thereof.

Disclosed are Bisphenol A (BPA), Bisphenol F, Bisphenol A diglycidyl ether (BADGE), and Bisphenol F diglycidyl ether (BFDGE)-free coating compositions for metal substrates including an under-coat composition containing a polyester (co)polymer, and an under-coat cross-linker; and an over-coat composition containing a poly(vinyl chloride) (co)polymer dispersed in a substantially nonaqueous carrier liquid, an over-coat cross-linker, and a functional (meth)acrylic (co)polymer. Also provided is a method of coating a metal substrate using the BPA, BPF, BADGE and BFDGE-free coating system to produce a hardened protective coating useful in fabricating metal storage containers. The coated substrate is particularly useful in fabricating multi-part foodstuffs storage containers with easy-open end closures.

One or more techniques are disclosed for a method for functionalized a graphitic material comprising the steps of: 1) providing a graphitic material; 2) providing a first molecule comprising a first group, a spacer, and a second group; 3) providing a second molecule comprising a third group, a spacer, and a fourth group, wherein the third group is a different group from the first group; and 4) bonding the first molecule and the second molecule to the graphitic material. Also disclosed is a tunable material composition comprising the functionalized carbon nanotubes or functionalized graphene prepared by the methods described herein.

A tone ring attachment for a disc brake rotor. The disc brake rotor has a disc portion that includes a plurality of circumferentially-spaced lugs. Each one of the lugs has a groove. A discrete tone ring body has a plurality of bosses. Each one of the bosses is receivable in a respective one of the grooves in the lugs. A dart projection extends from at least one of the bosses. The dart projection engages a respective one of the lugs to inhibit relative axial movement and relative rotational movement in at least one direction between the tone ring and the disc brake rotor. A tab is formed on at least one of the bosses. The tab is engageable with a portion of the lug to inhibit relative rotational movement in a second direction opposite the first direction between the tone ring and disc brake rotor.

Corrosion and chip-resistant coatings for high tensile steel components, such as automotive coil springs, can be formed from a coating composition comprising a primer having an epoxy resin with the proviso that the epoxy resin does not have an EEW of about 860 to about 930, a polyhydroxyl functional phenolic curing agent having a HEW of about 200 to about 500, and a platy filler. The primer contains less than 20 wt % zinc. The topcoat includes an epoxy resin having an epoxy equivalent weight of about 450 to about 1400, an elastomer-modified epoxy resin having an epoxy equivalent weight of about 1000 to about 1600, a foaming agent and a reinforcing fiber.

A friction-enhancing lacquer contains a binder and hard material particles. The hard material particles include a titanium-boron compound or consist essentially of a titanium-boron compound, such as titanium diboride. The friction-enhancing lacquer is applied to the surface of a machine part, such as a bearing inner ring, outer ring or other bearing component, in order to increase its coefficient of friction and minimize or prevent slippage relative to another machine part clamped thereto. Also a bearing component coated with such a lacquer.
