Technical overview

Solubor Flow is an aqueous suspension of sodium borate that comes in the form of a brownish liquid. For spraying, dissolve in water. For direct application, mix with a nitrogen solution. Always agitate prior to use. 

Storage: We recommend storing the product indoors, at a temperature range between 5-35°C. If frozen, the product returns to liquid phase when the temperature rises.

Shelf life: 8 months from production date.
