  • Publication number: 20150132239
    Abstract: The present invention relates to a material comprising dendritic molecules each constituted of fragments that are at least bifunctional and of fragments that are of least trifunctional joined together by ester or thioester bridges, alone or in combination with amide or urea bridges, said bridges being formed from two functions carried by different fragments, said molecules containing, on the fragments located at the ends of the dendritic branches, associative end groups capable of forming associations with one another by hydrogen bonds and joined covalently to the functions that are not involved in said bridges. It also relates to the method of production thereof, as well as to its uses and to compositions, notably cosmetic, containing this material.

  • Publication number: 20110319524
    Abstract: Resins and thermoset composites comprising them, these materials being able to be hot-fashioned. These compositions resulting from placing at least one thermosetting resin precursor, this thermosetting resin precursor comprising hydroxyl functions and/or epoxy groups, and optionally ester functions, in contact with at least one hardener chosen from carboxylic acids, in the presence of at least one transesterification catalyst whose total molar amount is between 5% and 25% of the total molar amount of hydroxyl and epoxy contained in the thermosetting resin precursor. Process for manufacturing these materials, process for transforming and process for recycling these materials. New solid forms of resins and of thermoset composites that may be used in the implementation of these processes.

  • Patent number: 6866803
    Abstract: A slip casting mold includes a water absorption layer having self water absorption capability and substantial water resistance. With the water saturation percentage of the water absorption layer being controlled, a slurry layer is deposited in the slip casting mold mainly under capillary attractive forces of the slip casting mold. The water absorption layer comprises an open porous body which is manufactured by stirring a mixture of an epoxy compound having at least one epoxy ring in one molecule, a hardener for reacting with the epoxy compound to harden the epoxy compound, a filler for developing self water absorption capability and mold releasability, and water into an O/W-type emulsion slurry, and casting the emulsion slurry into a mold impermeable to water, hardening the emulsion slurry in the mold while containing water.

  • Patent number: 6489405
    Abstract: A curable epoxy resin formulation comprising a) 40 to 100% by weight of an epoxy group-terminated polyester of a dimerised or trimerised fatty acid and a polyhydric alcohol, and 0 to 60% by weight of a diepoxide which is not an epoxy group-terminated polyester, b) a hardener for epoxy resins consisting of 50 to 99% by weight of a polyoxyalkylene di- or triamine and 1 to 50% by weight of a hardener which is not a polyoxyalkyleneamine, and comprising as further optional components c) a curing accelerator, and d) customary modifiers for epoxy casting resins, with the proviso that the sum of the constituents in component a) as well as in component b) is in each case 100% by weight, is suitable for use as casting resin formulation for encapsulating electrical or electronic components.

  • Patent number: 6462106
    Abstract: Disclosed is a novel amino-polyether-modified epoxy for an electrodeposition paint. The amin-polyether-modified epoxy compound is obtained by reacting amino polyether represented by a formula as follow: wherein m is an integer of 5 or more, R is hydrogen, methyl group or ethyl group, and n is 2 or 3, with polyglycidyl ether having a molecular weight of 1,000 to 7,000 and an epoxy equivalent of 500 to 3,500, wherein an equivalent ratio of a primary amino group of the amino polyether to an epoxy group of the polyglycidyl ether is controlled within the range of 0.52 to 1.0.
