Chemistry Application Area Application Use Features and Benefits

Belcor® 585

Enhanced Phos-phonocarboxylic

Acid (EPOC)

Open cooling systems

Mild steel corrosion control, all organic

and zinc based programs, effective

scale control in moderate hardness

waters

• Multifunctional deposit control in a single additive. • All organic corrosion inhibitor allows metal-free formulations. • Effective in a wide range of waters including soft and hard water. • Combines well with low zinc levels providing robust corrosion control in soft waters. • Halogen resistant. • Effective carbonate and phosphate scale control. • Forms synergistic combination with Belclene 440.

Belcor® 593 Tricarboxylic Acid

Closed cooling systems

Mild steel corrosion

• All organic. • Environmentally compatible alternative to nitrite in closed cooling systems. • Synergize with Belcor 575.• Cost effective, all organic programs across a range of water chemistry.

Belcor® 575

Hydroxyphos-phonoacetic Acid

(HPA)

Open cooling systems

Mild steel corrosion control

• Excellent all organic corrosion inhibitor allows for metal- free formulation.

All organic and zinc based

programs

• Effective in a wide range of soft and hard waters. • Combines well with low level zinc providing robust corrosion control in soft waters. • Forms outstanding synergistic combinations with Belclene 440.

Closed cooling systems

Mild steel corrosion control

• An environmentally acceptable solution for closed system corrosion control. • Effective in the presence of aggressive ions (chloride sulfate). • Provides effective inhibition in brine systems ( e.g., 30% CaCI2).

Belclene® 500

Phosphinocarbox-ylic Acid Polymer

(PCA)

Open cool-ing systems,

especially with halogen- based microbiological

control

Mid steel corrosion control

• Combines well with zinc providing strong corrosion protection in lower hardness waters.• Tolerates high levels of iron / oxidizing biocides. Formulations are not deactivated by iron and are effective with halogens.

Belclene® 640

Aminotris- (meth-ylene phosphonic

acid) (ATMP)

Open cooling systems

All organic programs

• Effective in non-halogenated systems. • Effective calcium carbonate scale control in moderately alkaline waters.

Belclene® 650

Phosphonobu-tane tricarboxylic

acid (PBTC)

Open cooling systems

All organic programs

• High performance calcium carbonate threshold inhibitor. • Effective calcium carbonate scale control and corrosion protection in highly alkaline waters.• Formulates well with Belclene 200 or Belclene 283 for complete all organic formulations.

Belclene® 660

Hydroxy ethylidene

diphosphonic acid (HEDP)

Open cooling systems

All organic programs

• Calcium carbonate threshold inhibitor.• Effective calcium carbonate scale control and corrosion protection in moderately alkaline water. • Formulates well with Belclene 200 or Belclene 283 for complete all organic formulations.
