Abstract: The present disclosure provides a polyurethane composition comprising a reaction product of an isocyanate component comprising one or more aromatic isocyanates, wherein the aromatic isocyanate has an isocyanate (NCO) content of about 2-30% NCO; and a polyol component comprising a polyol having an equivalent weight (EW) of about 1500-2500, an aromatic diamine, a moisture scavenger and a catalyst. A process for preparing the polyurethane composition and an article, coating or film comprising the polyurethane composition are also provided.

Abstract: A non-cytotoxic polyether polyurethane elastomer is made by reacting a polyether triol, polyether diol, and polyether prepolymer terminated with toluene diisocyanate. The reaction is catalyzed with a zinc based catalyst, such as zinc neodecanoate. Silicone oil is also added to the reactants. The polyurethane elastomer is a solid, soft elastomer having a hardness of from 15 Shore 00 to 50 Shore A. The elastomer is particularly suited for use as padding in sleeves, splints and braces where it is in contact with human skin.

Abstract: A fire-resistant coating composition and method that can be applied to various poles and substrates so as to substantially reduce the likelihood of fire and/or heat damage. The first-resistant coating composition having a first component and a second component. The first component may comprise isocyanate and a thickening agent, and the second component may comprise a multifunctional polyol, preferably a tetrafunctional polyol, most preferably an amine-based tetrafunctional polyol, titanium dioxide, diol ether, expandable graphite particles, a flame retardant additive, at least one thickening agent, and a catalyst.

Abstract: A multi-component variable hardness polyurethane system and method of creating a thermosetting composition having a particular hardness. In the preferred embodiment a polyurethane compound can be created having any desired hardness between 10 and 90 Shore A, by mixing the same two curative components in different proportions, according to the hardness desired, along with a stoichiometrically determined amount of isocyanate as a hardener.

Abstract: The present invention provides a composition comprising a solvated aromatic amine and a liquid carrier, wherein said solvated aromatic amine is the reaction product of an aromatic amine and at least one of any anhydride, an isocyanate or an acid in the liquid carrier. The present invention also provides a method of preparing a composition comprising a solvated aromatic amine and a liquid carrier, said method comprising the steps of providing a reaction mixture comprising: a) an aromatic amine; b) at least one of an anhydride, an isocyanate or an acid; and c) a liquid carrier; and heating the reaction mixture at an elevated temperature to provide the solvated aromatic amine in the liquid carriers. The present invention further provides the use of the compositions for the preparation of the curable compounds and for gasoline resistant coatings.

Abstract: A coating that can be adhered to a polyethylene gasoline container to substantially reduce its gas permeability, and a gasoline container treated with such a coating. A single-component cationic curing composition with increased impermeability to gasoline vapor uses a bis “F” epoxy in combination with a catalyst and oxetane. The invention takes advantage of a narrower ultraviolet absorption spectrum of the bis “F” epoxy, whereby ultraviolet radiation outside the UV absorption spectrum of the bis “F” will activate the catalyst, the highly active superacid from the antimonate anion, without any significant reduction of the cationic curing reaction. In the preferred embodiment the bis “F” and oxetane combination is used along with various additives included for flow and cosmetic purposes.
