Methylene bis 2,4 aniline (MOCA) (4,4-) is used to make
polyurethane products that are a significant component of many
common appliances. These are widely used in such items as gear
systems in modern office and home appliances, sporting goods,
mouldings for motor vehicle body parts and military equipment. The
compound is commonly used as a coating to set other glues, plastics
and adhesives. Its main purpose is to act as a curing agent for
other polyurethane and elastomer compounds. It is essential for
creating chemical reactions that bond other molecules in relatively
stable complex structures which comprise these compounds.

Methylene bis 2,4 aniline (MOCA) (4,4-) is a synthetic chemical
used to make polyurethane. It is moderately soluble in water but
soluble in alcohol, ether, organic and some solvents. It can be
gradually broken down by the action of sunlight in air and by
microscopic organisms in soil or water. When heated to the point of
decomposing it gives off toxic fumes of hydrochloric acid, complex
organic compounds and oxides of nitrogen.
The National Pollutant Inventory (NPI) holds data for all sources
of Methylene bis 2,4 aniline (MOCA) emissions in Australia.
