20150337146 | ALUMINUM CHELATE, METHOD FOR MANUFACTURING THE SAME, AND PHOTOCURED INK INCLUDING THE SAME - An aluminum chelate, a method for manufacturing the same and a photo cured ink including the same are revealed. First rosin resin is modified by epoxy and acrylic acid to get acrylic acid modified rosin resin. Then an aluminum chelating agent undergoes a chelation reaction with the acrylic acid modified rosin resin to form a plastic fluid whose chemical structure contains a photoreactive group and a chelate structure with aluminum. The plastic fluid can be added into photo cured inks so that the photo cured inks have better ink tack, ink flow, color density and stability. | 11-26-2015 |
20160002460 | EPOXY RESIN COMPOSITION, PREPREG, AND FIBER-REINFORCED COMPOSITE MATERIAL - An epoxy resin composition according to the present invention comprises an epoxy compound (A), a block copolymer (B) and a curing agent (C), wherein the block copolymer (B) is composed of a polymer block (a) comprising a (meth)acrylic polymer and a polymer block (b) comprising an acrylic polymer that is different from the polymer block (a), said epoxy resin composition having such a property that a cured resin product produced by curing the epoxy resin composition forms a microphase-separated structure. A cured product of the epoxy resin composition forms a highly ordered phase structure, and therefore has excellent toughness and stiffness. | 01-07-2016 |
20160068439 | MOLDABLE ENGINEERED STONE - This invention provides a moldable engineered stone composition comprising an ethylenically unsaturated acrylic polymer capable of being covalently crosslinked, a mineral particulate, and an ionic crosslinking agent which forms ionic bonds within the syrup of unsaturated acrylic polymer via unreacted acid groups, causing thickening prior to curing and prior to the formation of covalent bonds via the double bonds of the polymer chain. The composition is then capable of being extruded and molded in a press. Articles formed by curing the composition and methods for producing the composition are also disclosed. | 03-10-2016 |
