The present invention is directed to environmentally benign coatings that can prevent fouling of submerged structures and surfaces in the marine environment. The coating is essentially a grease composition composed of an organic acids salt, mineral oil, a solvent and alkaline silicate. The sulfonate thickener is an oil soluble dispersing agent selected from a plurality of organic acids in a form of alkali metal salt or alkaline earth metal salt thereof, such as calcium sulfonate. Coating compositions of the invention can be used to coat surfaces, such that when such surfaces are exposed to or kept submerged in seawater they will prevent fouling of such surfaces when exposed to the marine environment for extended time.

Described herein is a surface coating composition useful to provide durability and fire resistance to building panels, as well as methods to prepare the same. The coating composition comprises silicate present in an amount from about 65 to about 85 wet wt. %; hectorite clay present in an amount from about 0.15 to about 0.5 wet wt. %; silica present in an amount from about 1 to about 3 wet wt. %; and polysorbate present in an amount from about 0.5 to about 10 wet wt. %.

The present disclosure relates to one-pot, water-based/waterborne dry erasable paints, anti-graffiti paints, and surfaces. The dry erasable paints can be used to create dry erase coatings on virtually any type of substrate surface. The paints comprise an Si-containing compound, water, and an ingredient selected from the group consisting of binders, acids, salts, surfactants, and glycerin, and create a dry surface where the flexibility, adhesion, dye resistance, and chemical resistance best matches the substrate and use.
