Corrosion ProtectionDEYAP

Corrosion is a constant indiscriminate and costly enemy of metal, especially when packaging for storage and transportation.

Traditional corrosion prevention methods are costly and ineffective. They can be hazardous to personnel and the environment.

Vapor phase corrosion inhibitor (VpCI) technology represents a breakthrough solution in corrosion prevention. Our VpCI products protect metals with a chemically absorbed molecular layer that provides multi-metal corrosion protection. All surfaces, crevices, gaps, voids and other inaccessible empty spaces receive full protection. The VpCI barrier is self-renewing, even for repeatedly opened packages, and typically provides protection for up to 24 months.

Transportation Protection

Corrosion costs billions of dollars during the transportation of products. When water, moisture and oxygen come together, products are quickly exposed to corrosion. Especially in harsh sea and winter conditions, products become even more vulnerable to corrosion.

Long Term Storage

Corrosion becomes the biggest enemy, especially when products to be stored for long periods of time are not protected.

With DEYAP's environmentally friendly, highly efficient, cost-effective and easy-to-use VpCI bags and dehumidifiers, your products become resistant to harsh transportation conditions.

Outdoor Protection

The exteriors of production facilities, buildings, machinery located outside are areas open to corrosion formation.

DEYAP continues to provide services with all its knowledge and experience for the protection of all structures and products that have corrosion risk in the outdoor areas of companies.

What is VpCI?DEYAP

All corrosion inhibitor VpCI® products, whether used indoors or outdoors, work on the same principle: they protect metals from corrosion with the corrosion inhibiting vapor they emit.

The protection process starts when the vapor meets the metal surface and condenses, forming a thin layer of micro-crystals on it. The protective ions are absorbed by the metal surfaces and form a thin layer of molecules that prevent the connection between the metal and an electrolyte. The presence of an invisible layer of monomolecules does not remove any of the important properties of the metal; this is true even for the most sensitive electronic applications where conductivity, magnetic permeability or dimensional tolerance are crucial, and where the slightest deviations can lead to failure.

VCI products do not need to be applied directly to be effective; they provide protection through "evaporation". VCI products condense and are absorbed by all metal surfaces, including the most difficult to reach and recessed areas. Within reasonable limits, the VCI product provides protection that renews itself over and over again.
