Tectyl 502C Class II Translucent Wax Corrosion Preventive Compound QPL Approved
Military Specification MIL-PRF-16173E Grade 2, Class II

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.
