Ultrasonic Activated De-Painting (UADP)

Ultrasonically Activated De-Painting (UADP) Process is an environmentally friendly process to remove the paint and the primer from metallic components. The de-painting process involves the use of high energy ultrasonicator filled with an environmentally friendly water-based solution that is specific to the alloy being de-painted. The painted part is submerged in the ultrasonicator. The ultrasonic waves formed at the transducers of the ultrasonicator result in micro-cavitation that penetrates the paint via ultrasonic activation, gradually dis-bonding the paint from the part. This process does not require the use of harsh chemicals, high pressure spray, or media blasting. The ultrasonicator is closed for the entire de-painting process. Paint remnants in the ultrasonicator tank after UADP processing are easily filtered and discarded. This further reduces operator exposure and process risk. Extensive qualification testing has shown that there is no loss of substrate, corrosion or damage to the part after the de-painting process. The surface roughness is identical before and after the de-painting process.
