  • Patent number: 7816481
    Abstract: 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.

  • Patent number: 7169268
    Abstract: The present invention concerns a process for providing tertiary amine products which are color-stable, and have a greatly reduced tendency to take on color during their storage. According to the invention, an ethyleneamine derivative is added to the distillation pot prior to or during the distillation of the tertiary amine product. Preferably, the ethyleneamine derivative has a higher boiling point than the desired tertiary amine product so as to preclude the ethyleneamine from distilling over with the tertiary amine.
