Polyurethane composites comprising non-silane treated glass fibers and methods of manufacturing are described herein. The polyurethane composites can include (a) a polyurethane formed by the reaction of (i) one or more isocyanates selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, and (ii) one or more polyols; (b) a filler; and (c) non-silane treated glass fibers. In some instances, none of the glass fibers in the polyurethane composites are silane treated. The polyurethane composites comprising the non-silane treated glass fibers can have a flexural strength that is greater than the flexural strength of an identical composition wherein the non-silane treated glass fibers are replaced with silane-treated glass fibers. Articles comprising the polyurethane composites are also disclosed herein.

This invention pertains to coating compositions based on polyesters containing 2,2,4,4-tetrametbyM,3-cyclobutanediol (TMCD) and modifying polyester polyols. Coatings based on such polyester blends are capable of providing a good balance of the desirable coating properties, such as solvent resistance, acid resistance, retort resistance, crazing resistance, and bending ability, for metal packaging applications.

Disclosed is an acoustically and thermally effective engine and/or aggregate capsule which completely encloses the engine and/or aggregate.

There is provided a urethane resin that is excellent in adhesive strength, and maintains high adhesive strength even after exposure to high temperature and humidity. A urethane resin obtained by reacting a glycol-modified aromatic hydrocarbon-formaldehyde resin (A) modified with a glycol with a polyisocyanate (B) having two or more free isocyanate groups in a molecule.

A blowing agent for thermosetting foams is disclosed. The blowing agent is predominately the trans isomer of the hydrochlorofluoroolefin (HCFO) HFCO-1233zd alone or in combination with a hydrofluoroolefin (HFO), hydrofluorocarbon (HFC), hydrochlorofluoroolefin (HCFO), a hydrocarbon. The blowing agent is effective as a blowing agent in the manufacture of thermosetting foams.

An intumescent coating system contains: a polyol component; an isocyanate component; a latent crosslinker having two or more —NACH.sub.2OR groups, where A is selected from a group consisting of H and —CH.sub.2OR, and in each case R is independently selected from a group consisting of hydrocarbons having from one to four carbons, the latent crosslinker being present at a concentration of 30 weight-percent or more based on polyol weight; a boron component one weight-percent or more and 10 weight-percent or less based on total weight of the formulation; and expandable graphite at a concentration of 10 weight-percent or more and 50 weight-percent or less based on the total intumescent system weight; where the polyol and isocyanate are selected so that the reaction product at room temperature of the intumescent coating system components produces a coating having a tensile elongation of 40-percent or more as determined according to ISO 37.

The invention relates to a formulation comprising: —a first component which is formed from at least one isocyanate and at least one amino resin, wherein said amino resin is the condensation product of an aldehyde with a compound selected from the group comprising urea, melamine, benzoguanamine, glycoluril, acetoguanamine and mixtures thereof; and —a second component comprising at least one polyether, wherein said polyether comprises at least one ethylene oxide moiety and at least one isocyanate reactive group selected from the group comprising hydroxyl, amino, epoxy, and thiol, preferably hydroxyl.

A process comprising, consisting of, or consisting essentially of: forming a reaction mixture containing at least one polyisocyanate and an isocyanate-reactive compound comprising at least one alkoxylated triazine-arylhydroxy-aldehyde condensate composition wherein the alkoxylated triazine-arylhydroxy-aldehyde condensate composition is a reaction product of a triazine-arylhydroxy-aldehyde condensate and at least one alkylene carbonate, is disclosed.

A high-solid-content coating composition includes: (A) a hydroxy group-containing acrylic resin having a glass transition temperature (Tg) in a range of 20 C. to 70 C. and a weight average molecular weight in a range of 3,000 to 10,000; (B) a hydroxy group-containing polyester resin being a reaction product of a polyfunctional compound (b-1) having a carboxy group and a hydroxy group in total of three or more in one molecule, a monoepoxide compound (b-2) having a hydrocarbon group having 4 or more carbon atoms, and a caprolactone compound (b-3); and (C) a polyisocyanate compound, in which a solid content at the time of coating is 50 mass % or more.

A rigid polyurethane foam comprises the reaction product of an isocyanate and a thixotropic composition. The thixotropic composition comprises: a first polyether polyoi which is aromatic amine initiated and has ethylene and propylene oxide end capping; a second polyether polyoi having a viscosity at 25 C. of from about 500 to about 15,000 cps; a third polyether polyoi having a viscosity at 25 C. of from about 18,000 to about 60,000 cps and a functionality of from about 5 to about 7; and a hydrofluoroolefin. The thixotropic composition has a viscosity at 25 C. of from about 350 to about 5,000 cps. A method of forming a composite article comprising a substrate and the rigid polyurethane foam includes the steps of providing the thixotropic composition, providing an isocyanate, combining the thixotropic composition and the isocyanate to form a reaction mixture, and applying the reaction mixture to the substrate to form the composite article.
