This paper introduced the synthesis of three novel low viscosity, low toxicity, and room temperature curable epoxy resin, long application period, heating quick curing epoxy resin curing agent PA1, PA2, PA3. The amine value, viscosity, acid number, infrared spectroscopy, differential scanning calorimetry of three curing agents were analyzed. Analysis was discussed about these three curing agents cured epoxy resin. The adhesive dosage for the curing rate, adhesive and adhesive liquid flow properties, research the best curing the best ratio of agent and epoxy resin were studied. The results showed:the curing rate of PA1>PA2>PA3, PA2>PA1, Bonding Properties>PA3. In the glue liquid flow , these preparation of solid content of three kinds of curing agents are nearly, the coverlay are not too big difference after processing. The films of the fast curing epoxy have long application period and can be cured fast, good property for FPC manufacturers.
