摘要： The present invention discloses a waterborne amine curing agent, process of making such curing agent, and curable amine-epoxy compositions. The curing agent comprises the product of the reaction of a first polyamine containing primary amine functionality and a first polyepoxide in a ratio of moles of polyamine per equivalents of polyepoxide sufficient to provide an amine terminated intermediate (a) comprising an adduct of about two moles of polyamine and one mole polyepoxide, intermediate (a) being then reacted with urea or formaldehyde to provide an amine terminated intermediate (b), intermediate (b) being then reacted with a second polyepoxide to provide an amine terminated intermediate (c), intermediate (c) being end capped with a monoepoxide composition comprising an aromatic glycidyl ether or an alkyl substituted aromatic glycidyl ether, or a combination of both, to form a polyamine-polyepoxide adduct, and contacting the polyamine-polyepoxide adduct with a second polyamine having two or more active amine hydrogens.

摘要： An electrochemical oxygen sensor includes a sensing surface having a working electrode and a reference electrode, a hydrophilic layer formed from an oxygen diffusion-limiting layer emulsion overlaying the working electrode and a hydrophobic membrane formed from a hydrophobic solution disposed over the hydrophilic layer. The hydrophilic layer contains an epoxy network and a hydrophilic polymer. The hydrophobic layer contains an acetate copolymer and a cross-linking agent that reacts with the liquid epoxy resin in the hydrophilic layer forming the epoxy network where the hydrophobic member is water vapor and oxygen permeable.

摘要： A group of polyfunctional oxetane-based compounds having a structure as represented by general formula (I) or a product obtained by a reaction between a compound of general formula (I) and epichlorohydrin, an ester compound, or an isocyanate compound. When these polyfunctional oxetane-based compounds are used as cation polymerizable monomers in combination with an epoxy compound, the curing speed is high, and the cured product has highly excellent hardness, flexibility, adherence, and heat resistance.

摘要： Methods for manufacturing a pouch-type battery cell include disposing one or more electrode pairs between a first aluminum pouch layer and a second aluminum pouch layer, sealing the first pouch layer and the second pouch layer to form a peripheral seal joining the first pouch layer and the second pouch layer to form a pouch with an outer edge encasing the anode and the cathode, applying a photocatalytic polymer coating precursor to the outer edge of the pouch, and photo-curing the photocatalytic polymer coating precursor to form a conformal edge coating. The photocatalytic polymer coating precursor includes one or more photo-initiators, one or more acrylates, and one or more polyamines. The polyamines can include tertiary amines including α-CH functional groups, diamines represented by the formula H2N—R—NH2, wherein R represents saturated and unsaturated aliphatic moieties, and N,N′-(2,2-dimethylpropylidene) hexamethylenediamine. The photo-initiators can include Diphenyl(2,4,6-trimethylbenzoyl) phosphine oxide, 2,2-Dimethoxy-2-phenylacetophenone, and p-tert-butylphenyl 1-(2,3)-epoxy)propyl ether.
