Introduction: 4,4-Diaminobenzene sulfone, abbreviated DDS, white or light yellow crystalline powder.
4,4-Diaminobenzene sulfone is an aromatic amine curing agent. The curing conditions are 130-150°C for 3 days to 2 hours. It has excellent heat and corrosion resistance, good electrical properties, and low toxicity.
The so-called curing agent, also known as hardening agent, curing agent or modifier, is an indispensable processing aid and can meet the requirements of various application fields. By chemical composition can be divided into aliphatic amines, aromatic amines, amido amines, latent curing amines, urea replacement.
The aromatic amines need to be heat-cured, and the heat resistance, corrosion resistance, and mechanical strength of the cured products are much better than those of aliphatic amines.
4,4-Diaminobenzene sulfone is used as a curing agent for aromatic amines and is widely used in industry, intermediates for organic synthesis, curing agents for epoxy resins, intermediates for pharmaceuticals, macromolecular materials, and treatment of various types of leprosy. Wait.
