STORAGE AND HANDLING

The reaction of isocyanates with water leads to the formation of insoluble ureas and carbon dioxide gas, which can result in pressure buildup inside closed containers. Therefore, extreme care must be taken to assure containers used for TDI T-80 remain dry. containers that have become contaminated with moisture should not be subsequently sealed; otherwise a hazardous increase in pressure may result.
