Usage

General Description

1,1'-CARBONYLBIS(2-METHYLIMIDAZOLE) is a chemical compound that is used as a curing agent and accelerator in the production of epoxy resins. It is a dimer of 2-methylimidazole and is commonly known by its abbreviation MCI. This chemical is known for its ability to improve the flexibility, adhesive strength, and resistance to chemicals of epoxy resins. It is also used as a crosslinking agent in the production of thermoset polymers and as a hardener in the manufacture of coatings, adhesives, and sealants. Additionally, 1,1'-CARBONYLBIS(2-METHYLIMIDAZOLE) has been reported to have low acute toxicity, making it a relatively safe chemical for industrial use. However, it is important to handle this compound with care and use proper protective equipment due to its potential irritant properties.
