Corrosion & Rust Prevention : Protection Options Available

There are various methods of protection of metal spare parts, components, assemblies, machines and military hardware from corrosion and rust. There are following options of corrosion protection mainly used in industry :

• Oiling or Greasing (Contact corrosion inhibitors)
• VCI paper
• VCI Poly material
• Water soluble VCI liquid formulation

Each option of corrosion prevention has merits and demerits. Proper packaging solution involves selection of such option which gives optimum protection at minimum cost and ease of application in terms of saving of time and labour.

Advantages and disadvantages of above methods and options have been discussed as under:

Options for Consideration	Application of Oil, Grease etc	Using VCI Paper for Protection	Using Sealrust Poly Products for Protection
Suitability	Suitable where only metal items are to be Protected. Not suitable if metal parts contain rubber or other material	Suitable only for small items. Not suitable for Big size items and where visual inspection is required	Suitable for all sizes of Products and for all situations
Method of Application	To be applied by Brush or Hand. Time consuming Process	Packing or Wrapping is easy	Packing or Wrapping is easy
Drawback of Using	Degreasing and removing oil is expensive and time consuming	Not suitable if product require visual Inspection	No such Problems
Moisture Barrier Properties	No surety unless secondary Packing is done	No surety as Paper itself may absorb Moisture	Barrier of Moisture. Higher the thickness of Poly, better it is Barrier of Moisture
Availability and Sizes	In Liquid or Paste Form	While using large size Paper may get damaged. Hence suitable for only small components	Bags available with custom Width, Thickness and Color
Transparency	Transparent	Not Transparent	Almost Transparent and items can be inspected without opening packing
Additional Packing	Packed items require additional packing of material like Plastic or jute	Additional packing required to protect the paper	Additional Packing Not required. If necessary thickness of Poly can be increased
Cost/Benefits Effectiveness	Though Cost of Oil is not much, but this method is very Expensive due to cost of oiling and greasing and degreasing in terms of Labour Cost & Time involved and cost of secondary Packing	Costly than Sealrust Poly Packaging material in terms of monetary value and less features available than Poly material	Much more Cost effective than any other method of corrosion protection
