Which materials resist corrosion from pesticides?

Which materials resist corrosion from pesticides?

• A. Stainless steel
• B. Polyethylene plastic and fiberglass
• C. Aluminum
• D. Stainless steel, polyethylene plastic, and fiberglass

Answer: (D)

Corrosion resistance to pesticides depends on the chemical compatibility of the material with the formulations used. Stainless steel provides a protective oxide layer that protects against many pesticide components, making it a reliable choice for lots of handling equipment. Polyethylene plastic is highly resistant to a wide range of pesticides and solvents, so it’s commonly used for tanks, hoses, and containers. Fiberglass, when paired with chemical-resistant resins, also offers strong resistance to many pesticide formulations. Together, these three materials cover a broad spectrum of pesticides and conditions. Aluminum, by comparison, can corrode more readily under many pesticide exposures, especially with acidic or alkaline formulations, so it’s not as universally resistant. That’s why the combination of stainless steel, polyethylene plastic, and fiberglass represents the best set of materials that resist corrosion from pesticides.
