ZERUST® Replaces Desiccant-Barrier Packaging for Corrosion Control and Cost Reduction

Problem

An international crating company needed to find a better corrosion control solution than their current method of desiccants with sealed barrier packaging. Finding an effective solution was crucial to the company since their worldwide shipments pass through temperature and humidity swings that can accelerate corrosion. The company was unhappy with the desiccant-barrier packaging method because the desiccants became saturated and needed to be replaced at least every six months, increasing material and labor costs. Also, the barrier packaging frequently became punctured, and moisture rapidly filled the desiccants, making them ineffective. Once the desiccants became saturated, they became a source of corrosion by emitting moisture back into the package.

Solution

ZERUST® helped them implement a corrosion control system for five 40′ cargo containers, fully loaded with conveyors, controllers, and other factory equipment, to be shipped from the East Coast to the Middle East. The machinery was wrapped in ZERUST® ICT®510-C Ferrous Film, then heat-sealed and heat-shrunk to provide a tight enclosure. Additional multimetal corrosion protection was provided to the inside of each piece of equipment by ZERUST® VC6-1 Vapor Capsules. Before shipping, they were stored crated outside for over one year, waiting to be loaded. The ZERUST® system was very effective; all machines arrived at their final destination free of corrosion. Comparing ZERUST® to the desiccant-barrier packaging method, the company found that ZERUST® packaging was more effective and reduced costs by 57%.
