Containers of Suprasec 5008 should be kept properly closed and stored indoors in a well-ventilated area under normal factory conditions. Storage at temperatures ranging from 20 – 30 °Cprovides a convenient viscosity for handling. Storage at low temperature is not recommended because it may lead to some crystallisation; this material must therefore be protected from frost. If under abnormal storage conditions some crystallisation does occur, the material should be melted according to the procedures given in the publication PU 181- 15E. Storage at temperatures above 50 °C is not recommended, since this can lead to the formation of insoluble solids and also the viscosity build-up increases on extended storage.

Under the recommended storage conditions and if protectedfrom humidity and contaminants, i.e. in properly sealed drums,cans, etc., Suprasec 5008 has a provisional storage life of 9 months at the customer. In case of storage in bulk containers,please contact our Sales Representative for further details.Detailed information on how to obtain optimum bulk storageconditions, is available in the ISOPA document Guidelines forSafe Loading/Unloading, Transportation & Storage of TDI and MDI.

Reaction with atmospheric moisture, is prevented by storingSuprasec 5008 in carefully sealed containers under a dry airatmosphere. During handling, the product must be protectedfrom water ingress and from atmospheric moisture. Containersshould be re-sealed immediately after each sampling. Thereaction of isocyanates with water leads to the formation ofinsoluble ureas and carbon dioxide gas, which can lead topressure build-up in closed containers. Containers used forSuprasec 5008 must therefore be absolutely dry.The precautions necessary when handling Suprasec 5008, i.e.,MDI, and the decontamination procedures recommended to beused in case of spillage, are described fully in the publication PU193-1E; MDl-based compositions: Hazards and safehandlingprocedures. Should it prove necessary to melt Suprasec 5008,procedures are given in the publication PU 181-15E;Recommended melting procedures for MDI-based isocyanates.Should it prove necessary to melt Suprasec 5008 procedures aregiven in the the publication PU 181/15E Recommended meltingprocedures for MDl-based isocyanates.
