The present invention is generally directed to fire retardant compositions containing one or more fire retardants, one or more polymers (e.g., one or more biopolymers such as xanthan gum) and colloidal silica. Certain aspects of the present invention are directed to liquid fire retardant concentrate compositions that form a durable (e.g., water-resistant) barrier when applied. The compositions of the present invention optionally include micronized clay. The present invention is also directed to various other compositions, which may be referred to as water-resistant film forming compositions that contain one or more polymers (e.g., one or more biopolymers such as xanthan gum) and colloidal silica. The present invention is also directed to such compositions containing micronized clay and colloidal silica. A water-resistant barrier formed by the compositions of the present invention provide compositions suitable for use in a variety of other applications, in addition to fire retardant compositions.

The invention relates to the use of polymers and polymeric agents in preventing hard and soft fouling and corrosion, particularly although not exclusively, on the surface of marine equipment. Additionally, the invention relates to the novel combination of polymers with a ceramic coating, and its use as an anti-fouling or anti-corrosive agent.

A surface treated steel sheet excellent in weldability and corrosion resistance after electrodeposition coating is disclosed. The surface treated steel sheet of the present disclosure has a plated steel sheet having a Zn-containing plated layer and a surface treatment layer provided on at least one main surface of the plated steel sheet, wherein the surface treatment layer has at least a paint film as an outer layer, the paint film has an average film thickness of 0.5 m or more and 5.0 m or less, the paint film includes a binder resin, rust preventer, and conductive agent, and the binder resin includes a phenolic resin with a cross-linking degree of 40% or more or 80% or less.

The invention relates to a high temperature curable coating composition comprising: (a) at least one film-forming resin, (b) at least one crosslinker for the film-forming resin, wherein the crosslinker is not substantially reactive at temperatures under 120 C., and (c) an anticorrosive agent, which comprises a combination of a magnesium compound and a water-soluble Li salt. The invention further provides a method of coating a metal substrate and a coated metal substrate. The resulting coating has excellent anticorrosive properties without the use of Cr(VI) compounds, while being suitable for high temperature cure conditions typical in coil coatings.

Treatment compositions include a mixture of a corrosion inhibitor and a functionalized particulate in a solvent. The functionalized particulate includes both epoxy and amine groups. Surfaces coated with the treatment composition have improved corrosion inhibition performance, and/or greater duration of corrosion inhibition performance with respect to corrodents such as CO.sub.2 and H.sub.2S when compared to the corrosion inhibition performance of the same corrosion inhibitor coating in the absence of the functionalized particulate. The coatings including functionalized particulate are usefully applied to one or more interior and/or exterior surfaces of containments, separators, conduits, and other equipment, such well string completion components, that are contacted by fluids containing corrodents.

The present invention is directed towards curable film-forming compositions comprising metal particles; an alkaline earth metal compound comprising an alkaline earth metal oxide, an alkaline earth metal carbonate, an alkaline earth metal hydroxide, an alkaline earth metal sulfate, an alkaline earth metal monocarboxylate, an alkaline earth metal phosphate, or combinations thereof; and an organic film-forming binder.
