Embodiments of the present invention disclose a method for limiting peak exotherm temperatures in epoxy systems comprising the step of: combining an amine hardener, an epoxy and a diluent to form an epoxy system, wherein the diluent is selected from the group consisting of: ethylene carbonate, propylene carbonate, butylene carbonate, delta-valerolactam, delta-valerolactone, gamma valerolactone, butyrolactam, beta butyrolactone, gamma butyrolactone, and combinations thereof.

Cycloaliphatic carbonates as reactive diluents in epoxy resins

Accelerator compositions useful in the curing of epoxy resins having at least one amine and a glycerin and methods for making the accelerator compositions are provided.

Accelerators for polymerization of epoxy resins

The present invention relates to an etheramine mixture containing a monoether diamine and its method of production by alkoxylating an initiator with an alkylene oxide to produce a precursor polyol and reductively aminating the precursor polyol to form the etheramine mixture. The etheramine mixture may be used in variety of applications including as a curing agent for an epoxy resin or as a reactant in the production of polyurea.

Etheramines and their use as intermediates for polymer synthesis

The present invention relates to an etheramine mixture containing a monoether diamine and its method of production by alkyloxating an initiator with an alkylene oxide to produce a precursor polyol and reductively aminating the precursor polyol to form the etheramine mixture. The etheramine mixture may be used in variety of applications including as a curing agent for an epoxy resin or as a reactant in the production of polyurea materials.

Etheramines containing flexible and rigid segments and their use as intermediates for polymer synthesis

In another exemplary embodiment, an amine functional curing agent has an Amine Hydrogen Functionality (AHF) of at least 7 and an Amine-Hydrogen Equivalent Weight (AHEW) of at least about 50.

High functionality amine compounds and uses therefor

Provided herein are polyamine precursors useful in the manufacture of epoxy resins. Use of a polyamine precursor according to the invention provides an epoxy resin formulation having an increased working time over prior art amines used for curing epoxies. Increased working times translate to the ability to manufacture composites which could not be made using conventional epoxy curing agents, such as composite blades for wind-driven turbines. Such polyamines are also useful in polyurea formulations for lengthening reaction time, thus allowing more flow of applied polyurea coatings prior to gellation.

Polyether polyamine agents and mixtures thereof

Polyether polyamine agents and mixtures therefor

Provided herein are amine blends which may be used in place of N-aminoethyl piperazine as accelerator in the curing reaction of epoxy resins.
