摘要： The present invention relates to an epoxy resin system containing an epoxy resin and a mono-alkylated diamine. The epoxy resin system can further contain a second amine. The present invention also relates to a method for producing an epoxy resin system comprising combining an epoxy resin with a mono-alkylated diamine. The mono-alkylated diamines of this invention enhance desirable processing and cured properties of epoxy resin compositions without the negative impact on mechanical properties in the cured product normally seen with cycloaliphatic amine-based curing agents.

摘要： The present invention relates to an epoxy resin system containing the reaction product of an epoxy resin component and an amine-based curing agent component comprising a first amine component and a second amine component, and a method for producing the epoxy resin system comprising combining an epoxy resin component with an amine-based curing agent component to form an initial epoxy resin composition, the amine-based curing agent component comprising a first amine component and a second amine component; and allowing a chemical reaction to occur between the amine-based curing agent component and the epoxy resin component to form a cured epoxy resin composition. The first amine component is N-(3-aminopropyl) cyclohexylamine and the second amine component is the hydrogenated product of oligomeric structure from the 4,4′-Methylenedianiline process.

摘要： The present invention relates to a PVC plastisol composition comprising at least one vinyl chloride polymer selected from polyvinylchlorides and copolymers of vinyl chloride with one or more monomers; at least one plasticizer; at least one epoxy resin; and at least one isocyanate resin blocked with cardanol. The PVC plastisol composition of this invention provides strong adhesion to the surface of various metals or various undercoats of metals by thermal treatment for a short time at 100° C.-200° C. and is excellent in storage stability. In addition, it offers good rheological properties with improved yield value dosing and viscosity stability during applications compared to the nonylphenol blocked isocyanate PVC adhesion promotor.

摘要： A curing agent composition comprising anhydride and approximately equimolar amount of tertiary amine or imidazole and carboxylic acid, the amine being 1-piperidinylethanol (N-hydroxyethyl-piperidine, NHEP) represented by the structure below or an imidazole represented by the structure below: where R1=H, a C1-C20 straight chain or branched alkyl, or a monocyclic aryl; R2=a C1-C20 straight chain or branched alkyl, or a monocyclic aryl. The carboxylic acid is represented by RCOOH; R=a C1-C20 straight chain or branched alkyl, or a monocyclic aryl. The composition comprises a lower ratio of epoxy resin to anhydride (1:0.4-0.6) than typically used (1:0.8-1.1). In addition, it uses a higher loading of the hindered latent tertiary amine or the imidazole in combination with the carboxylic acid (wt % ratio of combined amine and carboxylic acid to anhydride ˜10%). With this composition a full cure can be achieved in less than 2 hr at a significantly lower temperature (˜100° C.).

摘要： The present invention relates to an amine-based curing agent comprising at least 1% by weight of at least one tertiary amine and, optionally, primary and/or secondary amines. The tertiary amine is preferably an N-substituted piperidine tertiary amine and, more preferably, N-hydroxyethyl piperidine (NHEP). The present invention also relates to an epoxy resin composition formed using this amine-based curing agent and a method of making the epoxy resin composition. These tertiary amines enhance desirable properties of epoxy resin compositions without the negative impact on mechanical properties in the cured product normally seen with tertiary amine-based curing agents.
