  • Type of Protection needed :

    Whether protection required during processing and Manufacturing or during storage, transportation and shipping?

    There are various options available for protection of metal components from corrosion and rust. Application of oil or grease is the conventional method of protection widely used in industry.

  • Packaging Environment and Packaging System :

    What are storage, transportation and shipping conditions - surrounding temperature, humidity, presence of salt, sulphur in the atmosphere?

    In adverse surroundings with high level of humidity, high temperature, salty atmosphere; the rate of corrosion is very high. It is, therefore, suggested to use sealrust® VCI packaging material for proper protection of metal surface. Use of VCI liner in cartons as a secondary packaging media will give added advantage for better protection.

  • Period and Duration of effectiveness :

    Whether protection from corrosion and rust required is for short term or long term; one week to eight weeks: or six months to two years or more?

    Duration of protection required is most important factor to be kept in mind while taking a decision regarding nature and type of corrosion protection material to be used in view of cost associated with the decision. For very short duration of 2 weeks to 4 weeks, application of oil or grease may be sufficient. For non critical applications application of anti rust material by brush or spray may serve the purpose. However, for long term protection one should use paper or poly having property of volatile corrosion inhibitor (VCI).

  • Method of application of VCI Products :

    Whether VCI application is by dipping, spraying, fogging, brushing or packing in paper or poly bags and wrappers?

    For protection of inner surfaces of metal items like tanks, containers, boilers, compressors, engines, water soluble VCI material may be used by dipping, brushing, spraying or fogging the metal objects. For tubular metal products like jumbo coils, best option is to use stretch cling film or wrapper having VCI properties.
