VCI, ALU barrier + desiccants , Desiccants

During storage and transport, non-treated metals can corrode. Corrosion is a result of oxidation or aggressive elements in the air. Traditional protection materials against corrosion such as oil, grease or paint are time and labour intensive and not environmentally friendly .

VCI (Vapor corrosion inhibitor) technology protects untreated metal against corrosion/oxidation.

VCI creates an invisible molecular protection layer on the metal. The technology evaporates out of the different products (PE film, Pur foam, paper, tablets etc) to saturate the closed environment. Once the environment around the metal is saturated, a thin molecular protection layer is formed on the metal hence avoiding corrosion. Moisture or impurities in the direct air around the metal can no longer influence metal to corrode.

VCI technology is incorporated in different materials:

• Polyethylene film
• Foam pieces
• Paper and corrugated
• Powder and tablets
• Liquids (oil-based, water-based, Soya-based)
• Emitters
• Laminated products

Benefits of VCI products:

• Multi metal corrosion protection: all metals are protected
• Keeps during minimum 2 years an effective protection against corrosion. VCI can be used for storage and long distance transport purposes
• Can be applied as a normal packaging
• So many different products and solutions available that almost each requested protection can be done: total corrosion solution
• Also protect places that are difficult to reach (complex machinery)
• Safe to use (recyclable, environmentally safe)
• Approved by NATO and other important companies
• Some products are even FDA approved
• Do not affect the metal : after unpacking the VCI layer simply evaporates in the air.
• Opening and re-closing of the packaging does not affect the VCI functioning
• No extra handling after use (the VCI layer disappears once the active VCI source around the metal is taken away)

Nefab has excessive know how and is able to offer a broad range of products. Nefab customizes solutions to cope with specific protection need in range with the logistic flow and packing process of the goods (individually protected, outdoor and indoor protection, direct availability of goods after unpacking)

Types of Corrosion Protection Products

Film:

Corrosion protection film is available in bags, covers, and wide film. Films are commonly used to pack large machines, to protect complete pallet loads, and to wrap metal parts that need protection. Film is available in wide sizes so that large covers can be produced. In addition corrosion protection film also allows large machines to be transported long distanced without further treatment against corrosion.

Foam:

Corrosion protection foam pieces are available in different sizes. This product is often added to an existing non-corrosion protected packaging. Foam is often used inside electrical and electronical cabinets, inside boxes and crates, or in existing hermetic packagings. Corrosion treated foam is complementary to film. A higher concentration of VCI in the foam creates a faster saturation of the closed environment. Film and foam combined; allow packing complex machines with high-tech components where complete protection of the whole environment is quickly achieved.

Corrosion protection paper is used to wrap metal parts, as protective layer between metal parts in metal boxes, as inner covering of wooden crates, or as sheet in small boxes. The paper can be coated on one side to make it more resistant to existing oil and grease on the metal.

Corrosion protection emitters are perfectly suitable for use in closed cabinets to protect electrical and electronical parts. Emitters are a very user friendly protection method – unpack emitter, stick emitter in cabinet, close cabinet – ready.

Corrosion protection powder is mainly used in closed systems, on the floor of big machines, in closed pipes and constructions. It can be blown in or added to closed loop water systems. Tablets protect metal parts in small boxes or small packaging.
