Chelation Value vs. Chelation Strength
DOW CONFIDENTIAL - Do not share without permission 15
– Capacity = Quantity (chelation value)
• How much metal can a chelant hold?
• One gram of VERSENE™ 100 controls 102 mg of calcium carbonate
• One gram of VERSENEX™ 80 control 80 mg of calcium carbonate
– Strength = Stability/Power
• The ability to form strong, stable metal complexes (more arms are stronger)
• To out-compete other metal complexing agents (the bigger the better)

Typical VERSENETM Chelant Use Levels in Cleaners
DOW CONFIDENTIAL - Do not share without permission 19
0.2 - 0.5 wt%
• For general protection against metal ions’ effects
• To assure good appearance of cleaning products
0.5 - 1.0 wt%
• To enhance cleaning product performance in hard water
• For concentrated cleaning products
1.0 - 3.0 wt%
• To provide a safety margin of protection
• Where the chelant is an important active ingredient when soils or stains have metal components
3.0 - 10.0 wt%
• Where the chelant is doing some of the cleaning
• Typically, for cleaning of metal surfaces

• Improve product quality and reducing costs in pulp and paper operations.
» Control metal-catalyzed bleach degradation in peroxide bleaching.
» Increase brightness gains in hydrosulfite bleaching of thermomechanical or refiner pulps.
» limit reactions that cause brightness reversion or produce colored complexes in pulp or sheet.
• Peroxide bleaching
• Hydrosulfite bleaching
• Kraft peroxide bleaching

The Right, Bright Idea for Sheet Appearance
®
Hydrogen Peroxide
DOW CONFIDENTIAL - Do not share without permission 25
• Elemental Chlorine Free (ECF) and Totally Chlorine Free (TCF) bleaching processes
• are the trend for pulp bleaching with reduced footprint to environment.
• Hydrogen peroxide H2O2 is the key bleach in ECF and TCF processes.– Increase bleaching capability
– Lower cost than chlorine dioxide
– Process flexibility
– Stable brightness with little yellowing
– No chloride in waste water and little pollution
– Lower corrosion
– Chemistry and heat recyclability
• Bleaching Mechanism
H2O2 + OH- OOH- + H2O
• Metal ions like Mn, Fe and Cu, catalyze the decomposition of hydrogen peroxide, so
some improvement in the efficiency of peroxide bleaching can be achieved if the metal
levels are controlled.
