Changzhou Fengfeng Chemical Co., Ltd. was founded in 1972. Its predecessor was mainly engaged in the production of crude oil cracking, dichloroethane, demulsifier for oil field, polyethylene, polypropylene, styrene and other products. At present, it is specialized in the R & D and production of downstream products such as various ethylene amine aliphatic amines and alicyclic polyamines. Its products involve epoxy resin curing agent series, polyaspartate resin Hydroxyethyl ethylenediamine (AEEA), chelating agent (EDTA) series, etc, In 1986, the first set of vinyl amine production plant in China was introduced from Japan and focused on the production and R & D of downstream derivatives with "vinyl amine" aliphatic amines as the main raw materials. In 1992, 3000 t / A epoxy resin curing agent (polyamide resin and epoxy resin accelerator DMP-30), 3000 t / a hydroxyethyl ethylenediamine A 500 t / a triethylenediamine (polyurethane catalyst) production unit. In 1998, EDTA (chelating agent) project took the lead in breaking through the production scale of 10000 tons in China In 2016, the company established an epoxy resin curing agent production base with a capacity of 10000 tons / year in Anhui Dingyuan Salt Chemical Industry Park. Its products include tertiary amine salt epoxy resin accelerator (DMP-30), tertiary amine salt composite salt, special phenolic amine epoxy curing agent, cashew phenol epoxy curing agent, alicyclic polyamine (modified) epoxy curing agent, fatty amine (modified) epoxy curing agent (low viscosity and high temperature) special polyamide resin curing agent, waterborne epoxy resin emulsion and waterborne epoxy curing agent. The company has continuously strengthened the R & D process of epoxy resin curing agent for special application scenarios, actively responded to the policy requirements of "environmental protection", especially made use of the unique R & D and production advantages of special phenolic amine curing agent, and continued to launch solventless (zero VOC, low viscosity), high mechanics (high toughness, long service life), super salt spray resistance, yellowing resistance (high gloss) Epoxy resin curing agent for different special application scenarios such as low temperature quick drying and underwater wet surface curing.
