Residual moisture on metal parts can become a problem in industry; it always marks a starting point for corrosion. Unpleasant consequences may become apparent only much later on – such as rusting under the final coat of paint. This means costly rework or, ultimately, even the product’s disposal.
If you want to prevent corrosion, you should, therefore, ensure absolute dryness. There are different methods available here. Drying by heat is obvious. However, this takes a lot of time and is energy-intensive.
Another method is known as the dewatering process: So-called hydrophobic molecules infiltrate the aqueous film on the metal’s surface, at which point the water beads up and is completely displaced from the surface. Dewatering is, therefore, a dependable, time- and resource-saving method of corrosion protection.
