210L iron drums, 250kg/drum Bulk
Storage
Since WANNATE® PM-200 is a reactive chemical, reaction with atmospheric moisture
happens easily and leads to the formation of insoluble ureas and carbon dioxide gas, which
can result in pressure build-up in closed containers and viscosity increase of the product.
Containers must therefore be absolutely dry and carefully sealed after congested with
nitrogen.
If crystallization does occur, the material should be heated by rolling the drum in a hot air
oven at 70-80℃ to melt it out, and should then be thoroughly agitated before use. Melting in
a water bath is not recommended.
Extended storage at temperatures above 50℃ is not recommended to prevent from the
formation of insoluble solids and viscosity increase.
Shelf Life
Under recommended storage conditions, the shelf life of WANNATE® PM-200 is one year
since the date of production.
Containers of WANNATE® PM-200 should be kept properly closed and stored indoors at
ambient temperature (15-35℃) in a well-ventilated area. Storage at low temperature (below
5℃) may lead to some crystallization; this material must, therefore, be protected from frost.
