Shelf Life
It should be storage in a closed container at 10°C to +30°C.
Standard shelf-life is 12 months. The expired day is marked on label for each drum.
Remark
Emulsion type silicones should be agitated thoroughly before use.
Emulsion type silicones may freeze at low temperatures, so users in colder regions should take special care with regard to storage.
Emulsion type silicones should be storage in a closed container at 10°C to +30°C temperature.
