CORROSION PREVENTIVE OILS (CPOs)

Comprehensive protection for metal components in storage, transport & manufacturing

Corrosion Preventive Oils are specialized formulations that safeguard metal components from rust, oxidation, and environmental degradation during intermediate storage, long-term warehousing, or global transport. CPOs form a protective film over the metal surface, preserving structural integrity and appearance until the next processing step or end use. Available as solvent-free, dewatering, and thixotropic grades, they serve industrial, automotive, aerospace, and military requirements.

Key Features & Functional Advantages

  1. Rust & corrosion protection:
    • Creates a reliable barrier against humidity, salt air, and airborne contaminants.
    • Options for short-, medium-, and long-term protection depending on storage or transit needs.
  2. Environmentally adaptive formulations:
    • Solvent-free oils: Eco-friendly, low odor, and safe for indoor use.
    • Dewatering oils: Displace residual moisture, light machining oils, and fines.
    • Thixotropic oils: Form stable, non-drip films on vertical and horizontal surfaces.

Product Types & Specialized Variants

Product Type Key Attributes Ideal Use Cases
Solvent-Free Oils Non-hazardous, high flash point, VOC-compliant Indoor metal storage, galvanized surfaces, cold-rolled sheets
Dewatering Oils Displace water/debris, quick-drying, light protective film Freshly washed parts, complex geometries, assembly line pass-through
Thixotropic Oils Gelled at rest, fluid under shear; non-dripping, robust film Vertical steel structures, stacked coils, outdoor/covered storage
Deep Drawing Oils Forming additives + rust inhibitors for dual functionality Sheet metal forming with simultaneous corrosion protection
Water-Soluble Oils Emulsifiable; multifunctional (cleaning + rust protection) Dual-stage applications in production lines
Weapon-Grade Oils Synthetic/mineral blends; high lubricity and rust protection Firearm maintenance, military storage, precision mechanical parts

Applications Across Industry

CPOs support a wide range of substrates and manufacturing stages:

  • Pipes, profiles & structural steels: Bars, strips, beams, galvanized sheets.
  • Components & assemblies: Bearings, small tools, fittings, fasteners.
  • Machinery & equipment: Gears, housings, hydraulic parts.
  • Storage & logistics: Indoor/covered warehousing, export packaging/overseas shipment.
  • Process integration: Cold rolling, assembly lines, electrostatic lubrication.

Formulation Highlights

Base oils: Highly refined mineral or synthetic.

Advanced additives include:

  • Phosphoric acid–ester corrosion inhibitors for long-term protection.
  • Antioxidants to prevent oil degradation.
  • Dewatering agents to remove residual moisture for cleaner application.
  • Anti-staining agents to preserve surface appearance.
  • Optional barium-free & low-viscosity variants for easier removal with alkaline degreasers.
