Industrial Coatings for Potash – Ecodur 201

Potash Plant
What is Potash?
Pronounced as pot ash, Potash refers to several forms of potassium salt and potassium-bearing materials, the most common being potassium chloride (KCL). It is currently one of the world’s three most important fertilizers, after nitrogen and phosphorus. But when combined with both those chemicals, potash can increase the yield of important crops like corn, soybeans, coffee, cotton, rice, etc. It also improves water retention, taste, color, texture, and resists crop diseases.
All commercial potash deposits originally come from marine deposits and are often found buried deep in the earth. To extract the potash, shaft mining is the typical method.
The old method of making potassium carbonate was to leach the wood ashes and then evaporate the resulting solution in large iron pots, leaving a white residue called ‘pot ash’. Potash is now the term more commonly applied to naturally occurring potassium salts and the commercial product derived from them.
Currently, about 95% of the world’s production of potash is used for fertilizing. The remaining amount is used in a variety of non-fertilized uses in industrialized economies like oil-well drilling fluid, snow and ice melting, steel heat-treating, water softening, soap manufacturing, etc.
Featured potash coating project
In January 2015, Ecodur 201 was used at a potash facility in the prairies of southern Saskatchewan. The temperature varied from 50 degrees Fahrenheit (10 C) down to a bitterly cold –22 degrees F (-30 C). We were dealing with the use of artificial heat on concrete pumps to raise the temperature above the Dew Point to avoid any trapped moisture.
Propane tiger torches were called in to heat the concrete before applying Ecodur 201S, which is VOC-free and non-toxic and the ideal product for use in temperature extremes and considerably outperforms most conventional epoxy coatings because of its unique ability to be sprayed in extremely low temperatures at a few degrees above the Dew Point.
Cure time took longer than normal and was achieved after 45 minutes to an hour at extremely cold temperatures.
The project was carried out in two stages:
60 mils of Ecodur 201s was sprayed on the upper portion of a containment wall with a clean finish achieved on the top edge of the wall. The concrete needed to be tiger torch heated over most of the area to remove the frost from the substrate.
