On top of the corrosion protection, Zerust® Valeno® film offers further properties including UV protection, high mechanical strength, transparency, flame retardation and ESD protection.
The Zerust® active anticorrosion molecules are impregnated in the polymer matrix and sublimate from both sides into the atmosphere. This means the user does not have to worry which way a round the product is used. Depending on the design, specific metals and alloys are protected both through direct contact and via the vapor phase within the enclosed packaging. The corrosion-preventing properties are in accordance with TL 8132-0043, Level 3.
Once the Valeno® film is opened, the protective molecules evaporate from the metal surface without leaving residue after one to two hours, and the packaged product can be assigned to its intended use without having to undergo any additional processing. Zerust® VCI is an odorless, non-toxic and invisible vapor.

The corrosion protection time depends on the application. Our team will estimate it with you. Long term corrosion protection for up to 15 years is possible, if provided instructions, specific logistic and technical packaging guidelines are followed.
Valeno® is available in a variety of different shapes and sizes, for instance flat, tubular and semi-tubular film, side gusset bags, box covers, bags, Ziploc bags, sheets, shrink film, bubble film, automatic packaging film, etc.
MAIN FEATURES: Valeno® corrosion protection film is based on polyethylene and active VCI molecules embedded in the polymer matrix. Active on both sides.
PROPORTION VCI/SURFACE TO BE PROTECTED: 1 m2 of film can protect up to 10 m2 of metal surface. The ratio of VCI to area to be protected varies depending on factors such as packaging design, logistical processes, part pre-treatment, etc. Therefore, prior technical consultation may be required. Our technical support will be happy to advise you.
PROTECTIVE COAT FORMATION: Approximately two hours for a 1 m3 hermetically sealed package at 20°C. The closer the product is to the VCI source, the shorter the protective layer formation time.
