    • A curable amine flux composition is provided, comprising, as initial components: a resin component having at least two oxirane groups per molecule; an amine fluxing agent represented by formula I: wherein R1, R2, R3 and R4 are independently selected from a hydrogen, a substituted C1-80 alkyl group, an unsubstituted C1-80 alkyl group, a substituted C7-80 arylalkyl group and an unsubstituted C7-80 arylalkyl group; wherein R7 and R8 are independently selected from a C1-20 alkyl group, a substituted C1-20 alkyl group, a C6-20 aryl group and a substituted C6-20 aryl group or wherein R7 and R8, together with the carbon to which they are attached, form a C3-20 cycloalkyl ring optionally substituted with a C1-6 alkyl group; wherein R10 and R11 are independently selected from a C1-20 alkyl group, a substituted C1-20 alkyl group, a C6-20 aryl group and a substituted C6-20 aryl group or wherein R10 and R11, together with the carbon to which they are attached, form a C3-20 cycloalkyl ring optionally substituted with a C1-6 alkyl group; and, wherein R9 is selected from a hydrogen, a C1-30 alkyl group, a substituted C1-30 alkyl group, a C6-30 aryl group and a substituted C6-30 aryl group; and, optionally, a curing agent. Also provided is a method of soldering an electrical contact using the curable amine flux composition.
    • 提供了一种可固化胺助剂组合物,其包含作为初始组分的树脂组分:每分子具有至少两个环氧乙烷基团的树脂组分; 由式I表示的胺助熔剂:其中R 1,R 2,R 3和R 4独立地选自氢,取代的C 1-8烷基,未取代的C 1-80烷基,取代的C 7〜80芳烷基和未取代的 C7-80芳基烷基; 其中R 7和R 8独立地选自C 1-20烷基,取代的C 1-20烷基,C 6-20芳基和取代的C 6-20芳基,或者其中R 7和R 8与它们 连接,形成任选被C 1-6烷基取代的C 3-20环烷基环; 其中R 10和R 11独立地选自C 1-20烷基,取代的C 1-20烷基,C 6-20芳基和取代的C 6-20芳基,或其中R 10和R 11与它们 连接,形成任选被C 1-6烷基取代的C 3-20环烷基环; 并且其中R 9选自氢,C 1-30烷基,取代的C 1-30烷基,C 6-30芳基和取代的C 6-30芳基; 和任选的固化剂。 还提供了使用可固化胺助剂组合物焊接电接触的方法。
