Usage
4,4'-Diamino-3,3'-dichlorodiphenylmethane (MOCA) is an organic compound, and its main application pathways are as follows:
- Synthesis of Polyurethane Materials: MOCA is an important chain extender for polyurethane elastomers. In the production of polyurethane, isocyanate prepolymers need to react with chain extenders to form high - molecular - weight polyurethane polymers. MOCA has a relatively high reactivity with isocyanates, which can effectively extend the polyurethane molecular chain and improve the hardness, strength, wear resistance, tear resistance and other properties of the material. It is commonly used in the manufacture of high - load - bearing polyurethane elastomer products, such as sieve plates, rubber rollers, seals, etc. used in industries like mining, metallurgy, and petroleum. These products need to have good wear resistance and mechanical properties.
- Curing Agent for Epoxy Resins: MOCA can be used as a curing agent for epoxy resins. It undergoes a cross - linking reaction with epoxy resins to form a three - dimensional network structure, thus curing the epoxy resins. The cured epoxy resins have good mechanical properties, chemical corrosion resistance, and heat resistance. It is often used in the manufacture of some epoxy composites with high - performance requirements, such as in the fields of electronic potting materials and floor coatings. Electronic potting materials need to protect internal electronic components from the external environment. The epoxy resin cured with the participation of MOCA can provide good sealing and mechanical protection. Epoxy floor coatings need to have properties such as wear resistance and corrosion resistance to meet the usage requirements of places like industrial workshops and parking lots.
