摘要： 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.

摘要： Provided herein are catalysts useful in reductive amination, which include nickel, copper, zirconium and/or chromium, oxygen, and tin. The presence of the tin increases the selectivity of the catalyst in reductive aminations over the catalysts of the prior art.

摘要翻译： 本文提供可用于制造环氧树脂的多胺前体。 根据本发明使用聚胺前体提供了环氧树脂制剂，其相比用于固化环氧化物的现有技术胺具有增加的工作时间。 工作时间的增加转化为生产复合材料的能力，这种复合材料不能用传统的环氧树脂固化剂制造，如用于风力涡轮机的复合材料叶片。 这种聚胺在聚脲配方中也可用于延长反应时间，从而在凝胶化之前允许更多的涂布的聚脲涂料的流动。
