Toluene diisocyanate

Lupranate® T-80 Ex Korea must be protected from moisture. Oxygen and UV-light cause discoloration which normally does not affect the processing of the material. The recommended storage temperature is between 20°C and 40°C. Under these conditions and if moisture and oxygen are excluded, Lupranate® T-80 Ex Korea can be stored for at least 18 months. Drums must be kept airtight. Storage tanks should be blanketed with nitrogen. Storage at higher temperature can lead to discoloration and to a formation of solids. These solids cannot be dissolved by heating. Storage for longer periods under + 15°C can lead to crystallization. Crystallized material must be melted out by short term heating in a hot air oven. Product temperature must not exceed 40°C. Local overheating must be avoided, as Lupranate® T-80 Ex Korea will decompose with formation of gas at temperatures above 250 °C. Rolling of the drums in a hot air oven is the recommended method of dissolving the crystals. After melting out, the contents of the drum must be thoroughly mixed.

Labelling, transportation, storage, processing, waste treatment and disposal must comply with nation regulations. Occupational exposure limits are to be observed. Lupranate® T-80 Ex Korea is classified as very toxic by inhalation. It is irritating to the eyes, respiratory system and skin. It may cause sensitization by inhalation and skin contact. Lupranate® T-80 Ex Korea is classified as a category 3 carcinogen (i.e. a substance which causes concern for man owing to possible carcinogenic effects in animal experiments). Lupranate® T-80 Ex Korea is harmful to aquatic organisms and may cause long-term adverse effects in the aquatic environment. Before processing the product we recommend reading the safety data sheet. For further information consult our Technical information “Safety and Precautionary Measures for the Processing of Polyurethane Systems”. In order to avoid accidents the residual product in the drums must be handled with care. Any water or moisture which is allowed to enter the drum will react with Lupranate® T-80 Ex Korea and release carbon dioxide. Unless action is taken to prevent moisture entry or gas entrapment, the drums will become pressurized and could rupture. If it is intended to use BASF isocyanate materials for the manufacture of consumer goods (e.g. products which will come into contact with foodstuffs or with the skin, toy, etc.) or medical products, national and international regulations have to be observed. We recommend contacting our Sales and our Ecology and Product Safety departments.
