MDA-100 is an aromatic diamine mixture containing more than 99.0% 4,4 '-diaminodiphenylmethane and slight 2,4' -diaminodiphenylmethane. The structural formula is as follows:

The molecular weight is 198.26, and it is white or light yellow solid granule at room temperature.

MDA-100 as an important chemical intermediate, it can be widely used in MDI, HMDI,PI, PEI, epoxy resin hardener, performance thermoplastic, chain extender of PU elastomer etc. These products synthesized with it have excellent properties of mechanics, electrical-insulation, heat-resisting, radiation-resisting and abrasion-resisting.

Warehouse and Storage

storage: Warehouse should be dry, ventilated and protected from light. It is strictly forbidden to be heated to prevent oxidation. Leakage, sun and rain are strictly prohibited during transportation.

Shelf life: Under the recommended storage conditions, the shelf life is 12 month. The shelf life beyond can still be used if it is tested to meet the technical specifications.

Safety precautions: Burnable, but nonflammable; Spray water or use dry powder, carbon dioxide, foam extinguishing agent after fire.MDA-100 can invade the body through the eyes and skin. Symptoms include severe liver poisoning, fever, upper abdominal pain, jaundice, anorexia, kidney damage and eye irritation.Wear clean and complete protective equipment (protective clothing, gloves, boots, helmet) to protect the skin; Wear protective goggles, masks and respirators in case of contact with eyes, rinse immediately with running water for at least 15 minutes. If skin is touched unexpectedly, remove the contaminated clothing and rinse the skin with plenty of running water.
