Tectyl 502C Class II is a Qualified Product Listed (QPL) for Govt Designation MIL-PRF-16173E; Grade 2, Class II formulated to also fulfill the requirements of MIL-PRF-1713E Grade 2, Class I and MIL-P-116J, Type P-2 Specifications. Contrary to Class I, Class II indicates this product is lower in Volatile Organic Content/Compounds (VOC), not exceeding 2.8 lbs. per gallon (340 grams/liter).
Tectyl 502C Class II is a solvent-based, grease-like, semi-firm wax corrosion preventive compound designed to protect various ferrous (contains iron) and non-ferrous (no iron) metal/steel surfaces like installed gearboxes from corrosion without the need for removal. Tectyl 502C Class II cures to a translucent, amber-colored, soft wax film that is completely miscible with lubricating oil and greases, eliminating the overall necessity for removal in some cases.
Tectyl 502C Class II is the ultimate protection for manufactured cast and forged steel roles used in various rolling industries. A perfect choice for high-quality and reliable corrosion prevention for a wide range of applications in storage, machinery protection, and domestic or international shipping.
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.
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 1-2 mils.
Dry to touch in 1 hour, weather-resistant in 2 hours, and fully cured in 24 hours.
Covers 995 square ft. per gallon when applied at the recommended film thickness.
Can provide up to 6 months of outdoor protection and 2 years of indoor or undercover protection on metal substrates at the recommended dry film thickness.
