H12MDA

Chemical formula: C13H26N2

Structural fomula:

Molecular weight: 210.36

Technical indicators: Colorless or light yellow transparent liquid

H12MDA is an important chemical intermediate. Used as epoxy curing agent for polyamide resin and polyurethane rubber manufacturing.H12MDA is used to process all kinds of environment-friendly polyurethane coatings and adhesives with good transparency and yellowing resistance. Epoxy resin cured by H12MDA has excellent heat resistance, dielectric property, solvent resistance, mechanical properties, as well as excellent optical properties, weather resistance, and can be used in damping materials, optical materials, coatings, engineering plastics, adhesives and other fields.

Packed in 2001,closed steel drums,with a net weight of 190kg per drum.(adjustable)

Keep away from sources of ignition,heat,and light,store in closed containers,away from incompatible substances such as strong oxidants and acids,and store in a cool,dry,and ventilated place.

According to the storage and transportation of flammable chemicals and corrosive substances.

ACUTE/CHRONIC HAZARDS: H12MDA is corrosive.

H12MDA is probably combustible.

On resorption, predominant clinical signs of intoxication were hyperexcitability, excessive salivation, and convulsions in animals; repeated oral dosing (50 – 100 mg kg -1 d -1 in rats and mice for 10 and 16 d, respectively, 50 mg/kg in dogs for up to 82 weeks) resulted in gastrointestinal hemorrhagic inflammations, nephritis, and fatty changes to the liver. No changes in methemoglobin or in other hematological parameters were induced in cats on repeated doses of 50 and 100 mg kg -1 d -1, given twice per week over 2 months. Several in vitro and in vivo mutagenicity studies gave no evidence of a mutagenic or clastogenic potential.
