What is 4,4-Methylenedianiline CAS 101-77-9?
Usage restrictions:
Avoid direct contact. Local exhaust equipment should be installed in the operation area
Products exported to the European Union need to provide SDS documents and REACH test reports
Alternative solution:
It is recommended to use environmentally friendly curing agents (such as 4,4' -methylene bis (2, 6-diethylaniline), which have lower toxicity)
4,4-Methylenedianiline CAS 101-77-9 Use
Industrial curing agent
Epoxy resin curing: Endows the material with high tensile strength, heat resistance and electrical insulation
Polyurethane chain extender: Used in elastomers and waterproof materials (such as polyurea spraying process)
Chemical intermediates
Synthetic dyes (azo structure), pesticides and medicines (such as the antimalarial drug ethazine)
Restricted use range
Textiles/Leather: Do not use decomposable aromatic amine dyes (detection limit ≤20 mg/kg)
REACH Regulation: Third-party testing and certification are required (such as the ZDHC MRSL standard)
4,4-Methylenedianiline CAS 101-77-9 safety
Acute toxicity
Oral LD₅₀ in rats: 347 mg/kg (highly toxic)
Percutaneous stimulation in rabbits: 500 mg/24h (severe stimulation)
Carcinogenicity
The World Health Organization (WHO) has classified it as a Group 2B carcinogen (possibly carcinogenic to humans).
Long-term exposure may cause bladder cancer and liver cancer
Protection requirements
Operation protection: Wear a gas mask, rubber gloves, goggles and anti-toxic suit
Leakage handling: Cover with plastic sheeting and collect, avoiding contact with water (hydrolysis generates toxic gases)
