    Sodium Bisulfate

    Sodium Bisulfate is an effective alternative to sulfamic acid or citric acid for lowering the pH of drilling fluids. Sodium Bisulfate comes in the form of dry (anhydrous) water-soluble, odourless granules that are white to off-white in colour.

    The primary advantages of Sodium Bisulfate over citric or sulfamic acids are availability and cost-effectiveness. Di-Corp’s Sodium Bisulfate is sourced from within North America and therefore less subject to high overseas shipping costs and international supply chain interruptions.

    Physical Application

    When used as an alternative to Sulfamic Acid for pH adjustment, lab testing has shown that at least 50% more Sodium Bisulfate is required in order to achieve the same result.

    Mixing & Handling

    Under normal conditions of storage and use, hazardous reactions will not occur.

    Do not store dry product where exposed to moist conditions. Sodium Bisulfate is reactive or incompatible with the following materials: oxidizing materials, acids and alkalis.

    Rubber gloves, full clothing, rubber apron and eye and face protection are recommended when mixing to avoid contact with unprotected skin. Contaminated clothing should be laundered before reuse.
