Rust Protection for Marine & Offshore Environments
Salt accelerates corrosion. Marine conditions call for durable films, covered storage and sealed packing.
What puts metal at risk
Corrosion in this sector rarely has a single cause. These are the conditions we see most often.
Salt-laden air
Chlorides break down thin films and attack bare metal.
Condensation in transit
Temperature cycling forms condensation inside the packing.
Long exposure
Voyages and layovers last weeks to months.
Heavy equipment
Large parts need films applied by brush or spray.
Handling damage
Films must tolerate bumps and rubbing.
Inspection
Films should be easy to inspect and renew.
Matching the grade to the part
Start with the part and the process; the grade follows.
| Part / situation | Recommended grade | Why |
|---|---|---|
| Precision marine parts | KG-8 | 3–5 years; withstands seawater and salt spray |
| Large equipment and castings | KG-9 | Thick wax film resists salt spray, humidity and sunlight |
| Equipment shipped by sea | KG-1 | 2–4 years or more |
| Multi-metal or magnesium parts | KGY-1 / KGY-2 | Colorless hard film |

Frequently asked questions
Which oil resists salt spray best?
Among the standard grades, KG-2C / KG-3C and KG-8 list 96 h of salt spray on steel, and KG-9 lists 100+ h as a thick wax film.
Is the film suitable for outdoor storage?
Covered storage is recommended; KG-9 resists sunlight aging.
Do you hold marine certifications?
Contact us with your project requirements and we will confirm which documents are available.
How is KG-9 applied?
Heat to 90 °C and brush on; the film sets as it cools.
Can I run a trial for a specific voyage?
Yes — request a sample and describe the route.
