Order: One ton Delivery term: FOB,CNF,CIF Shipment: prompt Payment terms: T/T L/C AT SIGHT shelf life One year Quality: as per your requirement Application domain: 1. ODA as one of the important raw material of polyimide film, polyetherimide, aromatic polyamide which are belong to new type special engineer plastics material . 2. ODA as also the synthesis material of tetramino phenyl ether. 3. ODA also as the crosslinking agent and raw material of epoxy resin and polyurethane 4. ODA can take place of the benzidine which produce the azo dye, reactive dyes and aromatics. Using the ODA as the raw material we have developed all kinds of direct dye, such as bright red ,brilliant red, sand red, yellowish brown, green, grey, blue, brilliant yellow, black. It used for the dye of silk, hair, cotton, ephedra. Its color fastness and the use of dye is better than the dye of benzidine. Storage, Packing& Transportation: Packed in carton or fiber drum lined with aluminum film bag
