Bounce Back

Last updated: August 24, 2015

What Does Bounce Back Mean?

This is a phenomenon that occurs during painting or coating, when the substance being sprayed is reflected from the surface of the substrate. This has been a problem in the painting/coating industry due to the amount of observable wastes. The efficiency of corrosion prevention under these circumstances is quite small.


Corrosionpedia Explains Bounce Back

Spray painting or coating is one of the most efficient, aesthetic finish technologies that solve the problem of time management, and large and intricate surface protection. However, air spray painting has been replaced by airless spray painting due to the difference in bounce-back effect. Almost 20–60% of the painting or coating goes to waste when the air convectional spray method is used.

The advantage of airless spray painting is brought about by reducing bounce back through:

  • Reducing the velocity of the substance being sprayed
  • The reduction of viscosity and pressure of the substance being applied
  • The increase in volume of the substance being applied
  • The use of heaters and elimination of air in the process
  • The use of booths to retain the bounced back substance

The essence of removing bounce back is to ensure that a dry thicker film is applied with every pass of the coating or paint substance. By ensuring that the coating or painting due does not dry up in the air, the bounce back problem will be eliminated and hence corrosion prevention is enhanced.
