WHATSACHEL THE SOLUTION TO METAL ION CONTROL THAT MANY INDUSTRIES NEED, BUT FEW RECOGNIZE. Chelating agents are chemicals that "tie u p " metal ions. W h e n found unrestrained in aqueous solu tions, these metal ions can result in undesirable color formation, scale and sludge buildup, spoil age of organic materials, and other problems. Yet f e w industries realize the link between uncon trolled metal ions and the problems they create. Fortunately, there's a solution—VERSENE* chelat ing agents, f r o m Dow. W h e n heat transfer equipment is used w i t h water, salts o f t e n deposit t o f o r m scale. VERSENE chelating agents successfully remove and also prevent this scale f r o m f o r m i n g . And in the textile industry. VERSENE* 100 chelat ing agent improves cleaning effectiveness and helps stabilize dye shades, while VERSENEX* 8 0 chelating agent stabilizes peroxide bleach baths. For the pulp and paper industry, chelating agents
are used to control metal ions and protect bleach ing agents to boost brightness. VERSENE 100 or VERSENEX 8 0 chelating agents are used for h y d r o s u l f i t e systems w h i l e peroxide systems require VERSENEX 8 0 . Household, industrial and institutional cleaners are generally formulated with chelating agents. They act as builders by improv ing soil removal and allowing built-in water hardness p r o t e c t i o n .

«INGAGENT? For PVC polymerization, the addition of VERSENE 100 or VERSENE CA will reduce the incidence of polymer buildup and improve suspending agent performance. VERSENE chelating agents control metal ions anywhere they may be found in the polymerization process. This helps to ensure high quality plastic products and longer life of the manufacturing «g^. ^ ^ ^ ^ M equipment.

And VERSENE chelating agents really help out in other industrial applications as well. Like photography, metal cleaning and plating of copper, and radioactive decontamination. In fact, any industry can t u r n t o VERSENE chelating agents w i t h confidence when they need help with metal-ion isolation problems.
