Description

Zinc borate appears as a white powder of variable composition. (typically 45% ZnO, 34% B2O3 and 20% H₂O). Slightly soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. It is used as a fungus and mildew inhibitor, to fire proof textiles, and for other uses.;DryPowder; OtherSolid; PelletsLargeCrystals
