    摘要: An object of the present invention is to provide a modified cyclic aliphatic polyamine having a low viscosity and a small content of unreacted polyamine which can provide, when it is used as a curing agent for epoxy resin, an epoxy resin composition having an improved workability without adding solvent or diluent and an excellent property of epoxy resin cure product. The above modified cyclic aliphatic polyamine is obtained by addition reaction of a cyclic aliphatic polyamine such as isophoronediamine and norbornanediamine and an alkenyl compound such as styrene. The modified cyclic aliphatic polyamine thus obtained is added in epoxy resin to be used as a curing agent for epoxy resin.

    摘要: Products prepared from polycarboxylic anhydrides and active hydrogen-functionalized elastomeric polymers, in particular polyoxyalkyleneamines, are suitable as builder components (prepolymers) for epoxy resin compositions. The reaction products are distinguished by having a plurality of carboxyl groups, but no imide groups, in each molecule. The reaction products may optionally be further reacted with epoxy resins and may optionally be formulated together with polymers having at least one glass transition temperature of −30° C. or lower and epoxy-reactive groups and/or reaction products of said polymers with epoxy resins to provide resin systems useful in adhesives. Such adhesive formulations may additionally contain liquid and/or solid epoxy resins and/or hardeners and/or accelerators and/or fillers and/or and/or other impact-modifying components and/or rheology auxiliaries. Such compositions exhibit excellent shelf life and are particularly suitable as impact-resistant and peel-resistant adhesives in vehicle construction and in electronics. Particularly at very low temperatures, these adhesives exhibit very good impact and peel properties combined with very good corrosion resistance and aging resistance of the adhesive bond.

    摘要: An aqueous epoxy resin system suitable for coatings comprises (a) water, (b) at least one epoxy resin and (c) a curing agent prepared by (i) reacting at least one polyamine having at least 3 active amine hydrogen atoms per molecule and at least one epoxy resin in an epoxy equivalent to to polyamine mole ratio of from 0.9:1 to 1:10 to obtain an amine-terminated intermediate; (ii) reacting the amine-terminated intermediate with from 0.5 to 25 weight percent, based on the amine-terminated intermediate, of an acid-terminated polyalkylene glycol to yield an amine-terminated curing agent. The amine-terminated intermediate can be capped with a monoepoxide in an amine hydrogen to epoxy groups ratio of from about 1.5:1 to 30:1 prior to reaction with the acid-terminated polyalkylene glycol, or the amine-terminated curing agent following step (ii) can be capped with a monoepoxide in an amine hydrogen atoms to epoxy groups ratio of from about 2:1 to 30:1.
