NOX-RUST 502-DHS Class 2 provides excellent protection for manufactured cast and forged steel roles used in various rolling industries. A great choice for high-quality and reliable corrosion prevention for a wide range of applications in storage, machinery protection, and domestic or international shipping.

Product Uses

• Translucent, Amber-Colored, Corrosion Preventive Coating recommended for corrosion protection during extended undercover protection of internal or external machinery surfaces like steel transportation parts/components during storage and domestic/international shipping.
• Protects highly polished cold rolled steel and paper calendaring mill rolls during shipping.
• The translucent film permits easy visual inspection of mill roll surfaces for hardness and surface imperfections prior to shipment.
• Serves as an effective edge coating for steel coil and sheet stock during storage.
• Class II Volatile Organic Content/Compounds (VOC) does not exceed 2.8 lbs./gallon (340 grams/liter).
• Removal is possible with mineral spirits (or another similar petrolatum solvent), hot alkaline wash, or low-pressure steam.

Product Performance:

• When applied at the recommended wet film thickness (WFT) of 2-3 mils over the surface profile, it will deposit the recommended dry film thickness (DFT) of 0.9 mils.
• Fully cured in 30-45 minutes.
• Covers 1,125 square ft. per gallon when applied at the recommended film thickness.
• Can provide up to 1 year of outdoor protection and up to 5 years of indoor or undercover protection on metal substrates at the recommended dry film thickness.

Application Equipment Recommendations: 

• Pumps with ratios of 15:1 or greater are advised for efficient use of container content.
