Modified MDI


Product Introduction

DG5412 is a modified organism of Diphenyl methane diisocyanate(MDI) which has higher functionality isocyanate. It is mainly used for producing cold cure high rebound foam, which applies to furnitures, toys, automobiles and other fields.

Physical Properties




Brown liquid

Specific gravity (25)


Viscosity (25, m.Pas)


NCO content ( %)


Packing 200kg/drum or 20kg/drum  

             As per the packing requirements of customers.

Storage suggestions Store in sealed container in 15-35;

                          Store in dry and well-ventilative place;

                          Prevent from freeze.  


1DG5412 can easily react with water to produce insoluble urea compounds and release carbon dioxide, resulting in high pressure  of  the drums and higher viscosity. Therefore, during  the storage process, ensure the container sealed and dry and  fill dry nitrogen gas.

2Storage under low temperature below 10could lead to crystallize, prevent form freeze. When there is crystal,  heat it at 70-80 as soon as possible so that it can melt, then stir it enough and to be cooled before use. The melting temperature does not need to exceed 80.

3Storage under high temperature could lead to produce insoluble substance resulting high viscosity, so this product can not be stored under high temperature.

4If there are red-brown solid grain, use it after filter and ensure the packing  sealed, fill dry nitrogen gas to protect if allowed.

Safe Protection:

    DG5412 have low toxicity when inhalation and touching skin.  Due to low volatility, its toxicity is little when short time exposure under normal conditions. However, DG5412 is still isocyanate compounds, it could moderately stimulate eyes and slight stimulate skin and cause skin irritation.

    In order to avoid to touch skin directly and splash into eyes ,operate carefully and wear the necessary protection equipment (gloves, goggles, labour suit and so on).Once splash into eyes and touch skin, immediately washing eyes using lots of flowing water and washing skin using soap. If swallow, seek medical care immediately.
