Storage:
Since it 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.Containers of 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. 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 is one year since the date of production.
