What is degreasing

Degreasing is an important stage in pretreatment. There are mineral greases on metal surfaces which are preventing oxidation by cutting the direct air diffusion. These minerals bring on difficulties to phosphate and chromate conversion coatings.

Degreasing application can be applied at 50 – 90 ° C, 5 – 10 minute by wiping, immersion or spray. Temperature, time and concentration are the important parameters. If concentration or temperature is low, it can be compensated by long time application. Generally, it is preferred to use soft water in degreasing baths.

The easiest way to define grease on surface is to observe the workpieces in rinsing bath. If there are accumulated water droplets on workpieces, it means that grease is not completely cleared.
