In industrial and manufacturing environments, metal corrosion is one of the most persistent challenges affecting productivity, product quality, and cost efficiency. Whether in machining, component assembly, or storage, exposure to moisture and oxygen can quickly trigger rust formation. This not only compromises the surface integrity of parts but also leads to increased rework, rejection rates, and maintenance costs.
That’s where CUMI KOTE DW 120 Rust Preventive Oil makes a difference — offering superior protection and reliability for machined components during production and indoor storage.
Understanding the Need for Rust Preventive Oils in Manufacturing
Rust preventive oils play a vital role in safeguarding metal surfaces between various stages of manufacturing and storage. After machining or cleaning, even trace amounts of moisture left on a metal surface can initiate corrosion. When oxygen and water combine with iron, they form iron oxide (rust), which weakens the material’s surface.
To prevent this, a high-quality rust preventive oil forms a thin protective barrier that seals the metal against corrosive elements such as humidity, oxygen, and contaminants. This is especially important in industries like automotive, engineering, and precision manufacturing, where even minor rust can impact the accuracy and performance of components.
What Makes CUMI KOTE DW 120 Different from Conventional Rust Preventive Oils
CUMI KOTE DW 120 is a specially formulated rust preventive oil designed to provide long-lasting protection during ongoing production processes. It ensures corrosion resistance for machined components stored indoors and transported domestically — making it an ideal choice for manufacturers seeking reliability and cost-effectiveness.
Developed by Carborundum Universal Limited (CUMI)—a trusted name in industrial solutions—this product combines advanced chemistry with proven performance to enhance the life and durability of metal components.
Key Features and Benefits of CUMI KOTE DW 120
1. Excellent Water Displacement
After machining, cleaning, or washing, metal parts often retain surface moisture that can trigger corrosion.
CUMI KOTE DW 120 eliminates this risk by effectively displacing water molecules from the surface.
How it works:
- Breaks the moisture–oxygen link using surface-active agents that push away water molecules.
- Forms a uniform protective barrier preventing contact between metal and corrosive elements.
2. Superior Corrosion Protection
CUMI KOTE DW 120 provides dual-action protection—physical and chemical.
- The thin film seals the surface from oxygen and moisture.
- Corrosion inhibitors chemically passivate the metal.
This ensures:
- Reliable rust prevention under fluctuating humidity
- Enhanced durability during indoor storage
- Consistent protection for precision-engineered parts
3. Thin, Adherent Film for Precision Components
Unlike conventional oils that leave a greasy residue, CUMI KOTE DW 120 forms a thin, clean, adherent film ideal for:
- Fine tools and precision parts
- Components requiring further machining or coating
- Applications where easy removal and cleanliness matter
Its fast-drying nature ensures protection without slowing down production.
4. Economical and Efficient Solution
CUMI KOTE DW 120 offers excellent coverage and protection per volume, reducing consumption and overall operating cost.
Application methods:
- Spraying
- Dipping
- Brushing
Key economic benefits:
- Long-lasting rust protection
- Reduced oil consumption
- Lower cost of corrosion management
5. Environmentally Friendly and Safe Composition
With sustainability becoming a priority across industries, CUMI KOTE DW 120 is formulated without heavy metals or hazardous materials, ensuring worker and environmental safety.
This makes it ideal for manufacturers seeking environmentally friendly rust-preventive solutions without compromising on performance.
