During abrasive blasting and immediately after, the relative humidity is a critical factor, as the substrate surface becomes vulnerable to corrosion such as flash rusting. The electrolyte in atmospheric corrosion is usually the water in the air. Introducing dehumidified air into an enclosed work area will reduce the RH significantly. If the humidity is reduced to below 50% RH, you can effectively ‘hold the blast’ on uncoated, blasted steel for days â€â€� sometimes weeks! This typically will have a huge impact on a production cycle â€â€� imagine being able to blast non-stop for a week before having to stop, clean up and paint!
