    Usage Information
    • Typical formulations range from 8 to 16 gallons of product, blended in water to 55 gals.
    • INC 2219 also blends easily with water soluble corrosion inhibitors to formulate combination corrosion/scale products.
    • Ethylene glycol at 15 to 30% by volume is recommended for winterization, although some blends may require IPA instead.
    • The customer should evaluate their winterizing agent carefully prior to sending a finished product out to the field.
