Usage Note
For precise dosing, perform solution-based trials: typical dosage ranges from 5 to 50 ppm depending on application. Dissolve fully and agitate consistently to maximize effectiveness.
Safety & Handling
Use dust suppression and wear gloves, goggles, and a dust mask. Store sealed in a cool, dry area, away from acids and strong oxidizers. Avoid inhalation, as it may release SO₂ gas.
