When it comes to safeguarding metals during manufacturing, shipment, and storage, there are two primary methods to consider: Rust Preventatives (RPs) or oils, and Volatile Corrosion Inhibitor (VCI) packaging. Let's explore the benefits and challenges of each option to help you make an informed decision.
RP Oils:
Pros:
- Cost-effective for work-in-progress protection.
- Helps displace water from parts.
- Can be applied using automated equipment.
- Provides immediate protection upon application.
- Offers a wide range of options for different applications.
Cons:
- Requires thorough coating for effective protection.
- Messy to use and can attract dirt and spills.
- Must be washed off before secondary operations like painting or welding.
- Provides relatively short-term corrosion protection.
- Maintaining dip tanks can be challenging.
- Oils and solvents may require special handling due to their hazardous and flammable nature.
- Disposing of used oil can be costly.
VCI Packaging:
Pros:
- Easy to use without special equipment.
- Environmentally friendly and recyclable.
- Long-lasting protection for several years when used correctly.
- Safe and clean, with no health hazards or oil spills.
- Cost-effective with no special disposal fees.
Cons:
- Requires complete sealing of packaging for full effectiveness.
- Takes some time for VCIs to reach metal surfaces.
- Challenging to incorporate with large or complexly shaped parts.
- May not be suitable for applications where packaging is easily damaged.
At Highmark Solutions, we tend to prefer VCI packaging over RP oils. The flexibility of the VCI packaging and the faster deployment of protected parts with reduced cleanup generally outweigh the added costs. When you work with Highmark Solutions, know we will work with you to ensure your bare metal parts stay rust free for as long as required.
