Corrosion Challenges for Electronics and Electrical Equipment

Electronic and electrical equipment can be affected by corrosion even when the equipment is stored indoors or installed inside a cabinet. Humidity, condensation, salt air, temperature changes, industrial contaminants, sulfur compounds, and moisture introduced during transportation can attack metal contacts and conductive surfaces.

Corrosion may affect circuit boards, connectors, terminals, switches, relays, wiring, contacts, sensors, control components, and metal housings. Even minor surface corrosion can contribute to increased electrical resistance, intermittent connections, signal disruption, equipment malfunction, and premature component failure.

Cortec® VpCI® Solutions for Electronics

Cortec® VpCI® technology uses Vapor phase Corrosion Inhibitors that diffuse through an enclosed space and form a protective molecular layer on metal surfaces. The vapor can reach recessed areas, complex geometries, contacts, and other difficult-to-access surfaces without requiring direct application to every component.

Depending on the product and application, Cortec® solutions can protect electronics inside control cabinets, junction boxes, equipment housings, sealed packages, storage containers, and shipping systems. Other products provide direct cleaning, thin-film protection, conformal coating, moisture control, cushioning, or static-dissipative packaging.

VpCI® Emitters for Electrical Enclosures

Cortec® VpCI® emitters are designed to release corrosion-inhibiting vapors inside enclosed, non-ventilated spaces. These compact devices can be installed inside control panels, cabinets, junction boxes, instrument housings, and other electrical enclosures where direct application to every metal surface may be difficult.

Available emitter sizes include the VpCI®-101 Device, VpCI®-105 Emitter, and VpCI®-111 Emitter. The correct emitter should be selected according to the internal volume of the enclosure, ventilation, environmental exposure, protection period, and equipment configuration.

Emitters may be used with operating, packaged, or stored equipment when permitted by the product instructions and equipment manufacturer. The enclosure must be sufficiently closed to retain the protective vapor concentration.

Circuit Board and Electronic Assembly Protection

Printed circuit boards and electronic assemblies contain multiple metals, narrow spacing, complex geometries, and sensitive conductive paths. These characteristics can make conventional corrosion prevention difficult, especially in high-humidity, marine, tropical, industrial, or outdoor environments.

ElectriCorr® VpCI®-286 is an acrylic conformal coating developed for compatible new and repaired electronic assemblies. It combines moisture-intrusion protection with Vapor phase Corrosion Inhibitor technology to help protect coated circuit boards and difficult-to-reach metal surfaces.

Before applying any cleaner or coating, compatibility should be confirmed for the circuit board, components, plastics, elastomers, labels, existing coatings, optical surfaces, and equipment operating conditions.

Electronics Cleaning and Direct Surface Protection

Oils, grime, dust, salts, fingerprints, and industrial contamination can hold moisture against electronic and electrical components. Proper cleaning can help remove these contaminants before corrosion protection is applied.

ElectriCorr® VpCI®-238 is formulated for compatible electrical and electronic equipment used in enclosed or controlled environments. ElectriCorr® VpCI®-239 provides cleaning and thin-film corrosion protection for compatible equipment exposed to more aggressive outdoor, marine, industrial, or tropical conditions.

Equipment should be safely de-energized before cleaning or direct product application unless the product instructions and equipment manufacturer specifically permit another procedure. Adequate drying and ventilation requirements must also be followed before power is restored.

Corrosion-Inhibiting and Static-Dissipative Packaging

Electronic components may be exposed to moisture, static electricity, handling contamination, and changing temperatures during manufacturing, warehousing, and transportation. Packaging should be selected to address the sensitivity of the component and the conditions it may encounter.

Cortec® offers VpCI®-125 static-dissipative films and bags for applications requiring both corrosion protection and control of electrostatic discharge. VpCI®-130 Series foams can combine corrosion protection, cushioning, desiccant action, and antistatic properties for sensitive parts and assemblies.

Additional options include Desicorr® VpCI® pouches, Cor-Pak® products, emitter devices, foam tapes, and clean-room films for specialized electronic and aerospace packaging applications.

Electronics Manufacturing and In-Process Protection

Electronic assemblies may spend days or weeks waiting between manufacturing, testing, integration, and final packaging. During these in-process hold periods, exposed metal surfaces can be affected by humidity, fingerprints, process residues, and airborne contamination.

Cortec® VpCI® packaging, emitters, foams, and compatible surface-protection products can be incorporated into work-in-process storage and final packaging procedures. These solutions help protect parts without relying solely on conventional oils or heavy protective coatings that may require removal before assembly or use.

Storage, Shipping, and Long-Term Preservation

Electronic equipment can encounter significant temperature and humidity changes during warehouse storage, ocean transportation, air shipment, and movement between climate-controlled and uncontrolled environments. These changes can cause condensation to form inside packaging or equipment enclosures.

A corrosion-control packaging system may combine a properly sealed barrier, VpCI® protection, static-dissipative materials, cushioning, and moisture management. The correct combination depends on the equipment’s sensitivity, packaging volume, shipping method, storage duration, destination, and expected environmental exposure.
