Feature
Chemical name: 4,4'-Diaminodicyclohexylmethane
Molecular formula: C13H26N2
Molecular weight: 210.36
CAS No.: 1761-71-3
Melting point: 60-65℃(lit.)
Product Application:
H12MDA is a colorless or light yellow transparent liquid with a slight ammonia smell at room temperature. In addition to being used in the production of HMDI, H12MDA is mainly used in epoxy curing agents and is also widely used in coatings and polyamide materials.
Packaging:
208L galvanized drum, 180kg/drum
Storage and handling:
H12MDA should be stored in a cool, ventilated place away from fire and heat sources; avoid direct sunlight and keep the container sealed; it should be stored separately from oxidants, isocyanates
(esters), peroxides, and strong acids, and should not be mixed. Do not store in active metal containers and do not freeze. Equip with fire-fighting equipment of corresponding types and quantities. The storage area should be equipped with leakage emergency treatment equipment and appropriate containment materials.
From the date of production, the product is stored in the original sealed container under cool and dry conditions of 0~30℃. Be sure to keep away from heat sources and humid environments during storage.
Recommended melting conditions: The product may partially crystallize and phase separate under low temperature conditions. If the above situation occurs, the product needs to be heated at a temperature of 60℃-80℃ until the product becomes clear.
