LEB-H
HIGH pH ENZYME BREAKER

Description:

LEB-H is a high pH stable enzyme breaker. LEB-H is the breaker of choice for fluids having a pH of 6.0 or higher. Conventional enzyme breakers exhibit maximum enzyme activity at a pH of 5 to 6 and are lose than 50% active at pH 7. In contrast, LEB-H has maximum activity at pH 7-8 and greater than 80% activity at pH 10. This makes LEB-H ideally suited for the high pH of preserved biopolymer systems and reactive systems that become alkaline in pH level. LEB-H is a freeze-proofed suspension of active enzymes in carrier liquid.

LEB-H Benefits:

• Effective Up To 140 °F Functions up to pH 11.0
• Convenient Liquid Form Ideal for breaking Borate Gals

LEB-H Physical Properties:

• Form: Liquid Charge: NA
  
• Color: Light brown Chemical Family: Protein
  
• Odor: Fermentation Flash Point: None
  
• Solubility: Water, brine Wt. per Gal: 9.0 lbs.

Application and Use Rate:

The use rate or dosage of LEB-H will vary according to the application. Polymer type, fluid pH, fluid temperature and the presence of salts (KCI, CaCI2, etc...) all affect the amount of breaker required for a particular break time, flow condition and trench fill temperature. We recommend running break tests to determine the optimum and most economical dosage of LEB-H. The desired amount of LEB-H may be diluted with water to a volume which can be metered easily and added continuously on the fly. Batch mixing LEB-H is not recommended as premature gel breaks may occur.

Compatibility:

LEB-H must not be blended with any other additive (except water) prior to use.

Handling and Storage Recommendations:

LEB-H should be stored in cool, dry location. Shelf-life is typically 1-2 years but can be extended by storing under refrigeration. Keep all containers tightly closed. LEB-H is non-toxic and virtually harmless. It may be irritating It contacted with the eyes. It may irritate the skin of extremely sensitive individuals. Chemical splash goggles and impervious gloves are recommended when handling LEB-H. Refer to the Material Safety Data Sheet for more detailed information.

Packaging:

LEB-H is packaged in 1 gallon, 5 gallon, and 55 gallon containers.
