Frequently Asked Questions (FAQ)
4,4'-Methylenebis(2-methylcyclohexylamine), also known as MACM or DMDC, is a cycloaliphatic amine curing agent with CAS number 6864-37-5. It is widely used for curing epoxy resins to provide excellent thermal resistance and mechanical properties.
Its primary application is as an epoxy resin curing agent. It is also used in polyurethane chain extenders, high-performance coatings, structural adhesives, composites, and wind energy blade manufacturing.
MACM provides excellent chemical resistance, high glass transition temperature (Tg), outstanding mechanical strength, and superior optical clarity, making it ideal for high-transparency and high-durability formulations.
Our product meets a strict high-purity standard of ≥99% (with actual batch results typically reaching 99.83%), ensuring stable reactivity and low moisture content (≤0.5%).
It should be stored in a cool, dry, well-ventilated warehouse, away from fire, heat sources, and direct sunlight. Keep the container tightly sealed to prevent moisture absorption, and avoid contact with strong oxidizers and acids.
