Three Applications For Vapour Degreasing Solvents

Posted on: October 23rd, 2013 by canadianfinishing No Comments

As the name implies, vapour degreasing is a method of surface preparation in which parts are cleaned of contaminants using suspended vapour. Vapour degreasing solvents are heated in a chamber below the piece to be cleaned. The heated vapour condenses on the cooler surface of the part where it dissolves and captures the contaminants which then drip away. In some instances agitation may be applied to remove stubborn debris. Here are just a few applications for vapour degreasing solvents.

 When Other Surface Preparation Methods Might Cause Damage

 The use of vapour degreasing solvents is ideal in instances where aqueous (water-based) cleaning methods would be impractical or potentially harmful to the materials being cleaned. Vaporized solvents can be used to eliminate oil, grease, flux, wax and other non-water soluble debris that aqueous cleaning methods might struggle to remove. The process avoids the potential for both oxidation and detergent buildup on materials that might be especially sensitive to such secondary contaminants.

 Using Vapour Degreasing Solvents On Small Or Intricate Parts

 Because the solvents are suspended in a vapor, they are able to penetrate into tiny holes, recesses and cracks in the parts to be cleaned. This makes the process ideal for smaller components of electronic subassemblies, both metal and plastic as well as any other materials that might be difficult to thoroughly coat with more traditional liquid solvents.

 Finishing Preparation

 Degreasing is often the first and, some would argue, most important step in the finishing process. In order to ensure a uniform and pristine finish, all surface contaminates must first be removed and vapour degreasing solvents leave properly prepared for painting, coating, welding or any other finishing technique.

 Every cleaning and finishing process requires its own unique combination of techniques and materials.
