CL2213 - Phosphonic Acid (Scale Inhibitor)


CL2213 Phosphonic Acid is a scale inhibitor that will provide inhibition of Calcium Carbonate and Calcium Sulfate scales at concentrations between 0.5 to 5.0 ppm., depending on the type and severity of the scale problem.


Density (Lbs. /Gal):  9.193

Specific Gravity:  1.103

Flash Point (TCC):  >200oF

Pour Point:  -20oF

pH:  1.0 to 2.0


Fresh Water:  Soluble

High TDS Brine:  Soluble (depending on calcium content)

Calcium Tolerance:  Less than 8,000 mg./L.

Diesel Oil:  Insoluble

Heavy Aromatic Solvent:  Insoluble

Crude Oil: Insoluble


CL2213 may be used in water based drilling fluids either in addition to or in place of CL9390 when Calcium Carbonate or Calcium Sulfate scaling is problematic.  Typically 5-10 gallons of CL2213 added at the suction pit daily is sufficient.


CL2213 is shipped in 55 gallon plastic drums.  For information regarding safety precautions in handling, health hazards, and exposure, please refer to the safety data sheet.  In case of an emergency, please call 800-669-8023.
