Frequently Asked Questions (FAQ)
Q: What is 4,4'-Methylenebis(2-methylcyclohexylamine) (MACM)?
It is an alicyclic amine co-monomer, commonly known as MACM or DMDC, with the CAS number 6864-37-5. It is widely used in high-performance polymer applications.
Q: What is the primary application of MACM / DMDC?
The product is mainly used as an epoxy resin curing agent. It is ideal for formulating high-durability coatings, structural adhesives, and composite materials requiring excellent chemical and thermal resistance.
Q: What is the purity level of your MACM product?
Our specification requires a purity of ≥99%. The actual test results show a high purity level of 99.83%, ensuring stable performance in sensitive formulations.
Q: What are the moisture and monamine limits for this chemical?
The moisture content is limited to ≤0.5% (tested at 0.02%), and the monamine content is strictly controlled at ≤0.1% (tested at 0.03%), which helps maintain optimal curing reactions.
Q: What is the physical appearance of 4,4'-Methylenebis(2-methylcyclohexylamine)?
It is a colorless, clear liquid with a low blackness level (specification ≤12, tested result is 8), which ensures it does not affect the color profile of the cured epoxy resins.
