Industrial Coatings for Chlorine – Ecodur 201

If you’ve ever swum in a swimming pool, you’ll be familiar with chlorine, the unique smelling chemical that keeps pools squeaky clean.
So what is this chemical that we’ve been swimming in since we were kids?
The History of Chlorine
Strangely, chlorine doesn’t exist individually as it combines with nearly every element, so it’s never found on its own in nature.
Inventor of Chlorine_Carl Wilhelm ScheeleIn fact, chlorine was first produced by Carl Wilhelm Scheele, a Swedish chemist who had the nickname “hard-luck Scheele” as he was thought to have made many discoveries and rarely got the credit for them.
Scheele founded chlorine when he combined the mineral pyrolusite with hydrochloric acid in 1774. He called chlorine “dephlogisticated muriatic acid”.
Scheele thought the gas produced in his experiment contained oxygen. But Sir Humphry Davy proved in 1810 that it was actually a distinct element without oxygen and called it Chlorine (derived from the Greek word chloros which means greenish-yellow).
Today, most chlorine is produced through the electrolysis of aqueous sodium chloride.
The Many Uses of Chlorine
1. Antiseptic
Chlorine is used in bleaches and disinfectants as it destroys the outer surfaces of bacteria and viruses. These solutions are regularly used in places such as hospitals, homes, hotels, and restaurants.
2. Water disinfectant
Chlorine is used in small amounts to treat drinking water as it greatly reduces the risks of waterborne illnesses.
3. Industrial and consumer products
Chlorine is used in the production of paper products, plastics, dyes, textiles, insecticides, solvents, and paints.
4. Pharmaceuticals
Surprisingly, it is estimated that chlorine chemistry is critical for the production of at least 93 percent of prescription pharmaceuticals currently sold in North America. These drugs are produced to treat high cholesterol, diabetes, cancer, stomach ulcers, anemia, depression, asthma, high blood pressure, inflammation, and epilepsy.
Featured Chlorine Coating Project
Early this year, Ecodur was used at a Nashville, Tennessee business park fountain that was built more than 20 years ago. The fountain’s rubberized lining was failing and causing significant leakage directly into the ground. The deterioration of the lining was further caused by coins thrown into the fountain and reacted with the chlorine in the water, which accelerated the corrosion of the lining. The owners wanted costs to be kept down, as replacing the lining is difficult to replace and removing them can get costly.
Ecodur was chosen as an overcoat – after the removal of degraded patches – because it could provide a tough, permanent non-toxic seal that has the ability to re-bond to itself. Ecodur is VOC-free and has zero noxious odors.
The applicator sprayed 50-60 gallons of Ecodur during one daylight shift in unshaded 90ºF temperature range. And in 24 hours, the coating achieved tack-free dryness, was fully cured, and had a final sign-off post inspection.
