Liquid epoxy curing agents that have improved latency over conventional liquid curing agents while retaining the physical properties of the cured material are disclosed. These liquid curing agents can be used for curing epoxy resins, or in combination with dicyandiamide (DICY) based curing agents in order to accelerate DICY curing.

One component epoxy curing agents comprising hydroxyalkylamino cycloalkanes

The disclosure relates to solving problems associated with conventional latent epoxy curing agents by providing a new class of latent epoxy curing agents. In particular, the disclosure relates to epoxy curing agents with improved storage stability and low use level (e.g., less than about 10 wt % relative to the epoxy compound) by forming solid solutions of certain classes of amines in polyphenolic resins.

Amines and polymeric phenols and usage thereof as curing agents in one component epoxy resin compositions

Exercise glove

A heat curable epoxy composition comprising the contact product of an epoxy resin, an epoxy curing agent and an accelerator for the epoxy curing agent, the curing agent or the accelerator comprising the reaction product of (a) a phenolic resin (a) of general formula: Where R1, R2, R3, R4 are each independently of one another a hydrogen or unbranched or branched alky group having 1 to 17 carbon atoms, and n is an integer form 0 to 50; and (b) a modified amine compound which is the reaction product of an epoxy resin and a methylated polyalkylenepolyamine having one primary or secondary amine and at least two tertiary amines of the general formula: Where R1, R2, R3, R4 and R5 represent hydrogen, methyl or ethyl; n and m independently are integers from 1 to 10 and; X is an integer from 1 to 10.

Low temperature curable epoxy compositions

Carboxylic acid salts of tertiary amines for use as an accelerator for an anhydride based epoxy curing agents are disclosed. The disclosed carboxylic acid salts of certain tertiary amines are latent anhydride accelerators and enable epoxy resin curing when heated to an elevated temperature (e.g., an onset temperature of greater than about 50&#xb0; C.).

Anhydride accelerators for epoxy resin systems

Epoxy curing agents comprising imidazole-isocyanate adducts, including 1-(aminoalkyl)imidazole-isocyanate adducts and especially 1-(3-aminopropyl)imidazole-isocyanate adducts, and their use as curing agents in heat curable one-component epoxy resin compositions. Epoxy curing agents comprising imidazole-isocyanate adducts comprising the reaction product of at least one imidazole, at least one polyisocyanate and at least one diamine.

Fast curable epoxy compositions containing imidazole- and 1-(aminoalkyl) imidazole-isocyanate adducts

A heat curable epoxy composition comprising the contact product of an epoxy resin, an epoxy curing agent and an accelerator for the epoxy curing agent, the curing agent or the accelerator comprising a urea compound which is the reaction product of an isocyanate and an alkylated polyalkylenepolyamine having one primary or secondary amine and at least two tertiary amines of the general formula: where R, R, R, Rand Rindependently represent hydrogen, methyl or ethyl, n and m independently are integers from 1 to 6 and; X is an integer from 1 to 10.

Low temperature curable epoxy compositions containing urea curatives

A heat curable epoxy composition comprising the contact product of an epoxy resin, an epoxy curing agent and an accelerator for the epoxy curing agent, the curing agent or the accelerator comprising the reaction product of (a) a phenolic resin and (b) a urea compound which is the reaction product of an isocyanate and an alkylated polyalkylenepolyamine having one primary or secondary amine and at least two tertiary amines of the general formula: where R, R, R, Rand Rindependently represent hydrogen, methyl or ethyl; n and m are independently integers from 1 to 6 and; X is an integer from 1 to 10.

Processes are provided for the storage and release of hydrogen by means of a substantially reversible catalytic hydrogenation of extended pi-conjugated substrates which include large polycyclic aromatic hydrocarbons, polycyclic aromatic hydrocarbons with nitrogen heteroatoms, polycyclic aromatic hydrocarbons with oxygen heteroatoms, polycyclic aromatic hydrocarbons with alkyl, alkoxy, nitrile, ketone, ether or polyether substituents, pi-conjugated molecules comprising 5 membered rings, pi-conjugated molecules comprising six and five membered rings with nitrogen or oxygen hetero atoms, and extended pi-conjugated organic polymers. The hydrogen, contained in the at least partially hydrogenated form of the extended pi-conjugated system, can be facilely released for use by a catalytic dehydrogenation of the latter in the presence of a dehydrogenation catalyst which can be effected by lowering the hydrogen gas pressure, generally to pressures greater than 0.1 bar or raising the temperature to less than 250&#xb0; C. or less, or by a combination of these two process parameters.
