Product Description

 

Product Description

COPOTHIN^® is an acrylic based, low molecular weight, polymer-type thinner used in most water-based drilling fluids up to 400°F It is effective thinner/deflocculant with exceptional tolerance to high temperature, divalent cautions, pH fluctuations and salinity. It will replace traditional thinners in most applications, exceeding those products in performance and cost effectiveness. COPOTHIN^® is used to maintain rheological stability in the presence of electrolyte contamination from salt, gypsum and cement. It will also aid in the prevention of high-temperature mud gelation.

Applications/Functions

• Deflocculates most water-based systems
• Helps minimize thermal flocculation
• Reduces shear strength development

Advantages

• Stable at temperature up to 400°F
• Readily soluble in water and can be added directly to agitated mud pits
• Excellent performance at low concentrations 
• Effective in the presence of salt and divalent ions
• Not pH dependent
• Environmentally acceptable

Typical Properties

• Appearance: Colorless to yellow, viscous liquid
• Specific gravity: 1.10-1.25; pH: 4-8
• Boiling Point: 180-212°F; Solid Content: 45%

Recommended Treatment

• A typical range is 1- 4 ppb, but specific drilling conditions will dictate a suitable concentration

Package

• 55 GAL DRUM or 5 GAL PAIL
