VCI Emitters — Vapor Corrosion Protection for Metal Parts

VCI emitters provide targeted, dry corrosion protection for metal parts stored or shipped in enclosed spaces where traditional packaging methods may not be practical. Using vapor corrosion inhibitor (VCI) technology, these emitters release protective vapors that circulate within sealed containers, cabinets, crates, and packaging to form a microscopic corrosion-inhibiting layer on metal surfaces—preventing rust and oxidation without oils, greases, or coatings.

VCI emitters are commonly used as a standalone corrosion protection solution or in combination with VCI bags and films to create a complete protection system for industrial storage, export shipping, and long-term warehousing. They are especially effective for protecting parts after cleaning with aqueous parts washers or solvent parts washers, when freshly cleaned metal surfaces are most susceptible to corrosion.

Within this category, SolventRS offers multiple emitter formats—including foam VCI emitters—to match different enclosure sizes, coverage requirements, and application needs.

FAQ

Q: What are VCI emitters?
A: VCI emitters are corrosion protection devices that release vapor corrosion inhibitors into enclosed packaging to protect metal parts from rust and oxidation.

Q: How do VCI emitters work?
A: Emitters release microscopic corrosion-inhibiting vapors that form a protective molecular layer on metal surfaces, blocking moisture and contaminants.

Q: Where are VCI emitters typically used?
A: They are used in industrial storage, export packaging, long-term warehousing, and any application where dry corrosion protection is needed without oils or coatings.

Q: What metals can be protected with VCI emitters?
A: VCI emitters are effective for carbon steel, stainless steel, aluminum, copper, brass, and mixed metal assemblies.

Cortec VpCI Emitters — Set-and-Forget Rust Protection for Enclosed Spaces

VCI emitters protect metal inside any enclosed space — electrical cabinets, control panels, junction boxes, toolboxes, gun safes, marine electronics, and stored equipment. Peel the backing, stick the emitter inside the enclosure, and the Vapor phase Corrosion Inhibitors saturate the air space, forming a protective molecular layer on every metal surface, including ones you cannot see or reach.

We stock Cortec VpCI-105 and VpCI-111 emitters plus foam VCI emitters. Each device protects up to 5 or 11 cubic feet respectively for up to 2 years, is non-toxic, and does not interfere with electrical, optical, or mechanical performance — which is why emitters are standard practice for protecting relays, contacts, and circuit boards in humid or corrosive plant environments.

Sizing is simple: measure the enclosure volume and match the emitter. Protecting bigger spaces or bagged equipment? Combine emitters with VCI bags and film. Call (847) 833-7010 for help or request a quote for case pricing.
