Kemphos P is a phosphodegreaser for pre paint treatments of steel, aluminium, zinc, copper and his alloys.
Kemphos P is a liquid product with a quickly solubility in water.
The dosage of the product is possible with manual method or with automatic dosing equipments.
In Kemphos P there are particulary raw materials that in one step remove soil and produce a strong thin layer of amorphous iron phosphate, the medium weight of this layer is 0,5-0,8 gr/m2.
This amorphous layer improves corrosion resistance and provides a valid support to following painting.
Kemphos P have good performance at low temperature (30°-50°C).
The keep of solution at the righit working title it is enought to use the analysis kit.
