20090301762OLIGOMERIC HALOGENATED CHAIN EXTENDERS FOR PREPARING EPOXY RESINS - An oligomeric halogenated chain extender composition comprising the reaction product of: (a) an excess of a halogenated phenolic compound; and (b) a halogenated epoxy resin; in the presence of (c) a solvent; and a halogenated epoxy resin composition comprising the reaction product of the oligomeric halogenated chain extender composition with an epoxy resin.12-10-2009
20100237292ISOCYANATE MODIFIED EPOXY RESIN AND EPOXY POWDER COATING COMPOSITION THEREOF - An epoxy resin composition comprises an isocyanate modified epoxy resin, which is a reaction product of (a) a multi-functional epoxy resin having an epoxy functionality of greater than about 2.2 and (b) a diisocyanate compound. An epoxy powder coating composition comprises the epoxy resin composition. The isocyanate modified epoxy resin has a high resin softening point and a high cross-linked glass transition temperature Tg for powder coating applications.09-23-2010
20100240816EPOXY RESIN COMPOSITION CONTAINING ISOCYANURATES FOR USE IN ELECTRICAL LAMINATES - A resin composition comprising oligomers having a molar ratio of isocyanurate to oxazolidinone greater than 1:1, wherein the weight average molecular weight of the oligomers is less than or equal to 3000, as measured by gel permeation chromatography. Such resin compositions may be combined with a hardener to form a curable composition. Also disclosed is a process for forming a resin composition, including: reacting diisocyanates to form isocyanurates; reacting isocyanate groups in the isocyanurates and unreacted diisocyanates with an epoxy precursor to form a resin composition comprising oligomers having: a molar ratio of isocyanurate to oxazolidinone greater than 1:1; wherein the weight average molecular weight of the oligomers is less than or equal to 3000, as measured by gel permeation chromatography. Such compositions may be useful in prepregs and laminates.09-23-2010
20100261837DIMETHYLFORMAMIDE-FREE FORMULATIONS USING DICYANADIAMIDE AS CURING AGENT FOR THERMOSETTING EPOXY RESINS - Substantially homogeneous solutions including dicyandiamide and phenolic hardeners having the general formula; where R′ and R″ may be the same or different and each represents R— or RO— radicals, with R being an alkyl or aromatic radical; R′″ is hydrogen, an alkyl or aromatic radical, —CH10-14-2010
20100317768EPOXY RESIN HARDENER COMPOSITIONS AND EPOXY RESIN COMPOSITIONS CONTAINING SUCH HARDENER COMPOSITIONS - An epoxy resin hardener composition including a reaction product of (i) a compound having at least one vicinal epoxy group, and (ii) an amino alcohol; an epoxy resin composition including the epoxy resin hardener composition and a compound having at least one vicinal epoxy group; and a powder coating composition including particles of the epoxy resin hardener composition and particles of a compound having at least one vicinal epoxy group.12-16-2010
20110028602EPOXY-IMIDAZOLE CATALYSTS USEFUL FOR POWDER COATING APPLICATIONS - A process of forming a solid epoxy-imidazole catalyst, the process including: contacting an imidazole, an amine, and one or more epoxy resins, in the absence of added solvent, to form a solid epoxy-imidazole catalyst. In other aspects, embodiments disclosed herein relate to an epoxy-imidazole catalyst, as well as curable compositions, processes for forming curable compositions, and processes for forming a thermoset resin using the epoxy-imidazole catalyst formed in the absence of added solvent.02-03-2011
