Wiping Iron Phosphate

Wiping iron phosphate processes are made degreasing and phosphating at the same time. It works at the room temperature and it is the economic method.

It is applied with sponge, yarn-free cotton cloth or brush on the iron, steel and galvanized parts. It is preferred for such large and heavy metal parts.

It is also recommended to increase the bath temperature for better degreasing and faster drying.

It is not recommended to determine the bath active content by analytical methods and subsequently adding. It is recommended to rebuild the working bath instead of adding phosphating chemicals over used solution and it should be renewed depend on the treated part amount.

Wiping iron phosphate coating ranges in color light yellow to blue-green.

Iron phosphate coats a very thin layer on the surface for that reason to prevent the corrosion, the parts should not stay in wet. It is recommended to make fast drying or passivation.
