Technical specifications
ULTRAFIP 638 is a liquid product suitable for all ferrous metals and plastic materials (for zamak, galvanized materials, and aluminum, subject to a reactivity test that can be performed at our Laboratory), specifically designed for removing polishing pastes and heavy greases.
It is used with excellent results in electroplating for costume jewelry components and in the eyewear and cutlery industries.
Thanks to its special formulation, free from boron, EDTA, chlorinated or petroleum solvents, it does not oxidize brass or copper, even during long contact periods. The use of ultrasound enhances its cleaning power.
The product is completely free of any type of VOC.
Use and Applications
ULTRAFIP 638 is used in immersion tanks, preferably with ultrasound.
Good degreasing results can be achieved at temperatures as low as 50-60 °C; for heavy soil situations (e.g. polishing pastes containing adhesives, which are very difficult to remove) it may be necessary to operate at temperatures up to 70-75 °C.
ULTRAFIP 638 is used in aqueous solution, by immersion, under the following operating conditions:
Bath temperature: 50 – 75 °C
Treatment time: 3 – 30 minutes
Bath concentration: 10 – 60 g/l

Bath control
Using a graduated pipette, take 10 ml of bath cooled to room temperature and place them in a 250 ml beaker.
Add approximately 50 ml of demineralized water and 3-4 drops of phenolphthalein indicator.
The solution will turn pink.
Titrate slowly with 0.1 N hydrochloric acid until the color changes from pink to colorless and read the ml of hydrochloric acid consumed, which represent the bath points.
A bath prepared at a concentration of 20 g/l will have a points value of 7,7 ml.

Power supply
For each missing point, add 2.6 kg of product per 1000 kg of bath.
The Fiprokim Technical Service will provide, during the system start-up phase, the optimal conditions of use, depending on the quality and quantity of foreign substances to be removed present on the surface of the material and the type of system itself.
