20110058948 | WINDMILL PROPELLER BLADE AND METHOD OF MAKING SAME - A windmill blade which comprises reinforcing fibers in a toughened resin matrix. The resin matrix is made from a composition which comprises (a) one or more epoxy resins and/or one or more epoxy vinyl ester resins, (b) one or more reactive diluents, and (c) at least one amphiphilic block copolymer. The amphiphilic block copolymer comprises at least two different polyether blocks and is present in the composition in an amount of from about 0.5% to about 10% by volume, based on the total volume of the matrix composition. | 03-10-2011 |
20110104498 | STRUCTURAL COMPOSITES WITH IMPROVED TOUGHNESS - A structural composite uses a block copolymer toughening agent to increase the fracture resistance (toughness) of the structural composite. The structural composite comprises (i) a carbon fiber reinforcing material and (ii) a thermosettable resin composition; wherein the thermosettable resin composition comprises (a) a thermosettable resin and (b) at least one block copolymer toughening agent. | 05-05-2011 |
20120010329 | CURABLE EPOXY RESIN COMPOSITIONS AND CURED PRODUCTS THEREFROM - Curable epoxy resin compositions, cured epoxy resin compositions, and processes of forming the same, including at least one epoxy resin, at least one sterically hindered amine curing agent and at least one non-sterically hindered amine curing agent which provides toughness properties to the curable composition and resultant cured product made from the curable composition. | 01-12-2012 |
20120142816 | Novel epoxy hardeners with improved cure and polymers with enhanced coating properties - A hardener composition for epoxy resins, the hardener composition including a mixture of 1,3-bis(aminomethyl)cyclohexane and 1,4-bis(aminomethyl)cyclohexane. A prepolymer hardener composition for epoxy resins, the prepolymer hardener composition comprising the reaction product of an epoxy with a mixture of 1,3-bis(aminomethyl)cyclohexane; and 1,4-bis(aminomethyl)cyclohexane. | 06-07-2012 |
20130274379 | POLYMER CONCRETE COMPOSITION - A curable composition for polymer concrete including (A) at least one epoxy resin composition comprising (A1) at least one epoxy resin, and (A2) at least one divinylarene dioxide; and (B) at least one hardener composition; wherein the divinylarene dioxide is present in the epoxy resin composition in a sufficient concentration such that the divinylarene dioxide reduces the viscosity of the curable composition and provides the necessary properties for cured polymer concrete product made from the curable composition. The divinylarene dioxide reduces the viscosity of the curable composition and, at the same time, provides the necessary properties for polymer concrete applications; and the divinylarene dioxide helps to increase heat deflection temperature (HDT) of the polymer concrete and improves the dimensional stability of a large polymer concrete part without sacrificing any of the other properties of the polymer concrete. | 10-17-2013 |
