Fast-Drying Rust Preventive Oil for Steel, Copper & Aluminum
- 1–2 years of protection; 2–3 years with plastic-bag packing
- Dense, thin film once the solvent evaporates
- KG-3 stays light yellow and resists yellowing
Long-Term Storage Fast-Drying Rust Preventive Oil
- 3–5 years of protection for precision parts
- Withstands seawater and salt spray
- Non-tacky, dust-resistant surface
Water-Displacing Fast-Drying Rust Preventive Oil
- Strong water displacement
- 1–2 years of protection on steel
- Some protection for copper, aluminum and magnesium alloys
Engineered for protection
A rust preventive film works by blocking water, oxygen and salts physically while polar inhibitors bond to the metal chemically. We tune both effects to the substrate and the protection period you need.
- Humidity and salt-spray tested
- Removable before painting, plating or welding
- Dip, spray or brush application

What is rust preventive oil?
Rust preventive oil is a protective coating applied to metal surfaces to keep moisture, oxygen and salts away from the metal. It leaves a thin film — oily, waxy or dry-to-touch — that slows or prevents corrosion during processing, storage and transport.
How long does rust preventive oil last?
It depends on the product, film thickness, packaging and environment. MOERY fast-drying grades such as KG-2 protect steel for 1–2 years (2–3 years with plastic-bag packing); long-term grade KG-8 is rated for 3–5 years on precision parts. Real protection time is always set by storage conditions.
How do I choose a rust preventive oil?
Start with four facts: the metal (steel, cast iron, electrical steel, plated parts…), the required protection period, the environment (indoor, humid, marine, export shipping) and how you will apply it (dip, spray or brush). Then match a grade — for example KG-2B for cast iron or KG-8 for multi-year storage — and confirm with a short trial.
What is the difference between rust preventive oil and a rust inhibitor?
Rust preventive oils are oil- or solvent-based and leave a protective film on the part. Water-based rust inhibitors are used in water-based fluids such as cleaning baths, coolants and rinse stages to give short-term, in-process protection. Many plants use both: an inhibitor in process, a rust preventive oil for storage and shipping.
Can rust preventive oil be removed?
Yes. Solvent-based fast-drying films can be removed with solvent cleaners, and MOERY KG-3 film is easily removed in alkaline cleaning solutions. Confirm the cleaning method before a part goes to painting, plating or welding.
