European Community (EC) Number: 253-733-5

Chemistry: PBTC
Usage: Calcium carbonate scale inhibition
Features: Halogenated systems and highly alkaline water

Description
Belclene 650 supplies excellent calcium carbonate and iron oxide control to cooling water treatment formulations for those who prefer phosphonate-based programs.

Application
Belclene 650 is widely used in industry as a sequestering agent and calcium carbonate scale inhibitor for industrial water treatment, industrial cleaning, and highly alkaline conditions.

Benefits
Belclene 650 provides the cooling water formulation:
• Excellent calcium carbonate scale inhibition and calcium compatibility in systems where LSI approaches 3.0
• Excellent choice when operating in high ORP and high pH conditions
• Good iron oxide dispersancy
• Moderate mild steel corrosion protection
• Very good halogen stability

As an excellent inhibitor to both scale and corrosion, Belclene 650 is an excellent stabilizer for zinc salt.
Belclene 650 is widely applied in the refilling system and circulated cooling system for oil fields, steel mills, and mines.
Belclene 650 can be used in situations of high temperature, high hardness, high alkali, and high concentration index.

Belclene 650 is excellent as both antiscalants and corrosion inhibitors, because of its structural feature of carboxylic acid and phosphoric acid.
Belclene 650 is stable and high efficiency in the condition of high hardness, temperature, pH value, and indexed matter concentration.

While usually building with other organophosphates, Belclene 650 also widely works together with zinc salts whose solubility it will increase.
Belclene 650 can improve zinc salt solubility.
Belclene 650 also have a higher tolerance to oxidation agents like chlorine or bromine in the system.

Belclene 650 is composed of the chemical compound 2-Phosphono-1,2,4-butanetricarboxylic acid in an aqueous solution.
Based on the composition, the product is a nonaromatic organo-inorganic compound indicated for use in industrial water treatment facilities as a scale/deposit control additive.

Phosphonobutane Tricarboxylic Acid, (or PBTC) has low phosphoric content.
It has structural features of both phosphoric acid and carboxylic acid groups, which enable its excellent scale and corrosion inhibition properties.
Its antiscalant property under high temperature is far better than that of organophosphines.

2-Phosphonobutane-1,2,4,-tricarboxylic Acid (PBTC) is a very effective scale inhibitor used in various industrial applications.
Due to its higher performance properties it is a very cost effective inhibitor compared to standard Phosphonates such as HEDP/ATMP.
This is mainly due to superior stability to chlorine, bleach and bromine.
In cooling water PBTC performs well at high PH or temperatures.
It further shows high effectiveness in high alkaline solutions such as industrial cleaners.
