ArmorThane pushes pre-harvest bin lining to reduce grain corrosion

ArmorThane says grain-bin corrosion can often be prevented before harvest with spray-applied polyurea linings that protect steel, preserve stored grain and support worker safety. The company is targeting operators heading into the harvest season across North America.

Why it matters: - Grain-bin corrosion can weaken storage structures, spoil grain and contribute to hazardous entry conditions. - Preventive lining work before harvest can reduce moisture intrusion and the corrosion cycle that often leads to costly bin failures. - The issue also intersects with federal grain-handling safety rules, including OSHA’s grain facilities standard.

What happened: - ArmorThane USA Inc. urged grain operators to line bins before harvest as part of a preventive-maintenance plan. - The company said seamless spray-applied polyurea linings can help keep moisture off steel and protect stored grain. - ArmorThane is working with grain operators and certified applicators on pre-harvest assessments and lining projects across North America. - Operators can learn more through Silo & Grain Storage Preservation or connect with a certified applicator through ArmorThane.

The details: - ArmorThane said bin corrosion often starts with daily temperature swings that create condensation on interior walls. - Moisture can mix with grain dust and organic acids in stored grain and corrode steel from the inside out. - Corrosion can thin bin walls, roughen surfaces and cause grain to cake and bridge against them. - Corrosion can also open paths for water intrusion that spoils stored product. - Troy Bacon, business development at ArmorThane, said most bin failures begin with condensation and grain dust quietly eating the steel from the inside. - Bacon said the goal of lining a bin is to break that cycle before it damages the structure or the grain. - ArmorThane said its spray-applied polyurea linings create a seamless, flexible barrier between stored grain and the steel or concrete shell. - The coatings cure quickly, becoming tack-free in under 45 seconds, which can reduce downtime versus slower-curing systems. - AquaSafe, ArmorThane’s pure polyurea, is certified to NSF/ANSI 61 for potable-water contact. - AquaSafe was tested at 450 percent elongation under ASTM D-412, which allows the lining to flex with thermal movement and bridge minor cracks. - ArmorThane said operators planning direct grain-contact use should confirm the right product and specification with the company. - For general bin and tank work, ArmorLiner bonds to metal, concrete, fiberglass and wood. - ArmorThane said corrosion, moisture and caking can contribute to the hazards workers face when entering grain bins. - OSHA’s grain handling facilities standard, 29 CFR 1910.272, sets requirements for entry into bins, silos and tanks and bars entry beneath a bridging condition or where wall buildup could break loose. - ArmorThane said lining a bin does not by itself satisfy OSHA requirements, but it can be part of a broader preventive-maintenance and safety strategy. - Bacon said the best time to line a bin is before it is full. - Bacon said a bin packed with grain cannot be lined and corrosion problems are better addressed before harvest.

Between the lines: - ArmorThane is framing corrosion control as both an asset-protection step and a safety measure. - The company is also positioning its coatings as a faster-turnaround option for off-season maintenance. - The messaging targets operators who want to avoid discovering damage in the middle of harvest, when downtime is most costly.

What's next: - ArmorThane is steering operators toward off-season assessments and lining projects before bins return to service. - The company expects corrosion prevention work now to protect a full storage season later. - Operators needing product selection for grain contact are being directed to confirm specifications with ArmorThane or a certified applicator.

The bottom line: - ArmorThane’s pitch is simple: line grain bins before harvest, while they are empty, to reduce corrosion risk, protect stored grain and help support safer bin entry.
