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.
