A process and system to protect an apparatus such as parts, components, equipment, vehicles and the like from environmental effects such as corrosion or rust using the oil-based VCI and a water-based film. In one aspect of the disclosure, the water-based film can be applied on top of a layer of an oil-based VCI that has been applied on an apparatus such as a vehicle (described below). In other aspects of the disclosure, the oil-based VCI is mixed in with the water-based film and then applied on top of the apparatus. In still other aspect of the disclosure, the oil-based VCI is applied on top of a layer of water-based film that has been applied to the apparatus.

A corrosion inhibitor can include (a) an inorganic alkali and/or alkaline earth metal compound and (b) an aldehyde and/or ketone component comprising at least one aromatic ring comprising a ketone and/or aldehyde group and at least one pendant group represented by OR.sup.1. Each R.sup.1 is independently selected from hydrogen, an alkyl group, or an aryl group. The coating composition can be used in a multi-layer coating with additional coating layers. Methods of preparing coating compositions with corrosion inhibitors and substrates at least partially coating with such compositions are also included.

Disclosed is a corrosion inhibition coating, comprising: a base comprising a matrix and a metal within the matrix; and an inhibitor comprising: zinc molybdate, cerium citrate, magnesium metasilicate, a metal phosphate silicate, or a combination thereof, wherein the metal within the matrix comprises aluminum, an aluminum alloy, zinc, a zinc alloy, magnesium, a magnesium alloy, or a combination thereof. Also disclosed is a substrate coated with the corrosion inhibition coating.

The present invention relates to a powder paint for aluminum wheels, and more particularly, to a curing agent. The corrosion-resistance improved powder paint for aluminum wheels, which is the present invention, includes 70 to 80 wt % of an acrylic resin, 8 to 12 wt % of dodecanedioic acid, and 3 to 10 wt % of sebacic acid, and the corrosion resistance of the powder paint is improved according to the composition of the present invention, so that it is possible to reduce occurrence and diffusion of corrosion on corner pails.

A novel solution of an amine carboxylate. type of vapor phase migratory corrosion inhibitor (VCI), suitable for use as part of a corrosion resistant coating for metal surfaces. The solution contains a high concentration of the amine carboxylate VCI, thus facilitating, on application of the coating, a dry film coat containing an effective corrosion-inhibiting amount of the amine carboxylate VCI.

The present invention relates to a corrosion inhibitor and a corrosion inhibiting coating provided for coating a metal, particularly but not exclusively steel. The inhibitors pigment will also protect aluminium and magnesium alloys. The corrosion inhibitor particularly protects a sacrificial coating such as zinc or zinc alloy on galvanised steel, which in turn therefore provides improved corrosion resistance to the underlying steel. The present invention comprises an organic cation in a cation exchange resin.

Methods of employing corrosion inhibitors with oxidizing and/or non-oxidizing biocides, such as peroxycarboxylic acids, to provide corrosion protected compositions are disclosed. Various corrosion inhibitors further provide biocidal efficacy in addition to the corrosion protection providing further benefits for application of use. Methods of employing corrosion protected biocide compositions, such as peroxycarboxylic acid compositions, for corrosion protection are particularly well suited for treating fluids intended to flow through pipes, namely in the energy industry, water and paper industries, etc. Methods providing suitable corrosion protection in comparison to untreated systems and corrosion protected systems using conventional corrosion inhibitors, such as quaternary amines and imidazolines commonly used in the industry, are disclosed.
