Ethylsilicate polymers and a method of making, specifically ethylsilicate polymer binders with reduced levels of regulated volatile organic compounds (VOCs) for use in the coatings industry and casting industry, and more specifically to stable, fast cure ethylsilicate polymer binders with low levels of regulated VOCs.

Provided are a resin molded body and applications thereof. The resin molded body includes a resin layer containing a resin and a compound represented by Formula (1), and on at least one surface of the resin layer, a protective layer that contains at least one substance selected from the group consisting of urethane resin, acrylic resin, and polysiloxane. In Formula (1), Het.sup.1 represents a divalent 5-membered or 6-membered aromatic heterocyclic residue. X.sup.a, X.sup.b, X.sup.c, and X.sup.d each independently represent a hetero atom, and Y.sup.a, Y.sup.b, Y.sup.c, Y.sup.d, Y.sup.e, and Y.sup.f each independently represent a hetero atom or a carbon atom. A ring bonded to Het.sup.1 may have a double bond at any position.

The current disclosure provides reinforced aerogel compositions that are durable and easy to handle, have favorable performance in aqueous environments, have favorable insulation properties, and have favorable, reaction to fire, combustion and flame-resistance properties. Also provided are methods of preparing or manufacturing such reinforced aerogel compositions. In certain embodiments, the composition has a silica-based aerogel framework, reinforced with an open-cell macroporous framework, and includes one or more fire-class additives, where the silica-based aerogel framework comprises at least one hydrophobic-bound silicon and the composition or each of its components has desired properties.

The present invention relates to hydrophilic anti-fog coatings. In particular, the coatings use two types of nanoscale particles, colloidal silica and porous organosilicate micelles, in a polyurethane matrix. The invention is an anti-fog coating for optically clear substrates (polycarbonate, polyurethane, nylon, polyester and other clear plastics) without the need for a primer and glass substrates with an additional primer layer, comprising monosized colloidal silica nanoparticles and porous organosilicate micelles in a polyurethane matrix. The silica is preferably 1-5% by weight and the micelles are loaded at 0.1 to 10% volume percentage by volume. The polyurethane prepolymer is dissolved at 10-40% by weight in a mixture of tertiary amyl alcohol and diacetone alcohol to customize for dip, flow or spray coating processes.

Stabilised and aquated polymeric silicate compositions are described in which the compositions are poorly condensed compositions in which the silicates are resorbable and are capable of undergoing efficient dissolution to provide bioavailable soluble silicic acid. In particular, stabilised and aquated polymeric silicates are described that are capable of intravenous delivery, useful in the treatment of cancer or systemic infection, or for topical administration, e.g. in the form of a solid or semi-solid ointment useful in the treatment of wounds or the prevention of bacterial infection.
