Technical specifications
ULTRAFIP 638 is a liquid product, suitable for all ferrous metals and plastic materials (for zamak, galvanised and aluminium subject to reactivity test in our laboratory), specifically for the removal of polishing pastes and heavy grease.
It is used with excellent results in electroplating for costume jewellery parts and in the eyewear and cutlery industry.
Thanks to its special formulation, free of boron, EDTA, chlorinated or petroleum solvents, it does not oxidise brass or copper, even with long periods of contact. The use of ultrasound enhances its cleaning power.
The product is totally free of any type of VOC.
Usage and Applications
Ultrafip 638 is used in immersion baths, possibly with ultrasound.
Good degreasing results can already be achieved at temperatures of 50-60 °C; for heavily soiled situations (e.g. polishing pastes containing adhesives, which are very difficult to remove) it may be necessary to work at temperatures of up to 70-75 °C.
ULTRAFIP 638 is used in an aqueous solution, by immersion, under the following operating conditions:
Bath temperature: 50 - 75 °C
. Treatment time: 3 - 30 minutes
Bath formation 10 - 60 g/l

Bathroom control
With a graduated pipette, take 10 ml of the cooled bath at room temperature and place it in a 250 ml beaker.
. Add about 50 ml of demineralised water and 3-4 drops of phenolphthalein indicator.
The solution will turn pink.
Titrate with 0.1 N hydrochloric acid slowly until it turns from pink to colourless and read off the ml of hydrochloric acid consumed, representing the bath score.
A bath prepared at a concentration of 20 g/l will have a bath score of 7.7 ml.

Power supply
For each missing point add 2.6 kg of product per 1000 kg of liquor.
The Fiprokim Technical Service will provide, during plant start-up, the optimum conditions of use, depending on the quality and quantity of the foreign matter to be removed from the surface of the material and the type of plant itself.
