A coating composition for producing high performance heat-resistant coating materials for a variety of substrates including steel and metal and non-metal substrates as well as laminate structures and self-contained substrates. The coating composition includes an epoxy resin system comprising a fluorene-structured epoxy monomers and the like, along with a crosslinker or curing agent and a catalyst or catalyst package. The coating compositions when amine-, phenyl hydroxyl-, or carboxyl-functional may also be used as crosslinkers or curing agents.

An epoxide based composition that can be cured at a temperature of less than about 70 C is disclosed. The composition is a liquid at ambient conditions and, therefore, can be used to rehabilitate the interior surfaces of pipelines. The epoxide-based composition comprises at least one epoxide component (component A) and at least one curing agent component (component B) wherein (A) the epoxide component comprises a phenyl glycidyl ether polyepoxide; and (B) the curing agent component comprises a mixture of two salt compounds formed, respectively, from an N-alkanol piperidine and a carboxylic acid bearing 7-12 carbon atoms, and N-cyclohexyl-N,N-dialkyl amine and a carboxylic acid bearing 7-12 carbon atoms.

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.

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.

Latent epoxy resin formulations are suitable for liquid impregnation processes for production of fibre composite materials.

Provided is a liquid epoxy resin composition that is superior in workability and adhesion to a base material, and exhibits an unimpaired resin reliability even under a high-temperature and high-humidity environment. The liquid epoxy resin composition contains (A) an epoxy resin; (B) an imidazole-based curing accelerator; and (C) a maleimide compound. The weight-average molecular weight (Mw) of the maleimide compound (C) is 500 to 2,000, and a maleimide group equivalent per 1 mol of the maleimide compound (C) is 250 to 1,000 g/eq.

The present invention relates to a process for producing 2-(2,2,6,6-tetramethylpiperidin-4-yl)propane-1,3-diamine, which can be used as hardener in epoxide applications.
