Preparation of surface before powder coating is made in several stages:

First stage – deoiling: item surface cleaning of oiling, fuel, dust, mechanical particles by means of cleaning agent. 
Second stage – (intermediate) – washing: item surface washing after deoiling in technical water of any temperature within 3 minutes. 
Third stage – phosphating: by means of phosphate concentrate there is a phosphate film on the surface of an item, of 2 microns thickness which allows to economize to 9% of powder coating on better conductivity and item surface being homogeneous.
Forth stage (intermediate) – washing: washing of item surface after phosphate stage in technical water of any temperature within 3 minutes to remove from phosphate film of foreign solids.
Fifth stage – removing. Removing of item surface in distilled water.
Note: for time saving, it is allowed not to follow forth and fifth stages from coloring items preparation cycle, exploited inside.
Sixth stage – drying. It is held both, naturally and forced to get dry surface (without wet spots). Approximate time of drying naturally at temperature of environment 20°C – 5 minutes
Note: for items, having no strict requirements towards their surface quality, using of first and second stages only is possible because cleaning agent contains phosphate groups. In this case, not technical but distilled water is used on second stage. 

Cleaning agent

It is used for deoiling of all the kinds of steel (including galvanized) and aluminum.
Surface treatment methods:
          1. Spray (difusion). Consumption is 10 grams per 1 liter of technical water with temperature more than 20○C, to coat within 3-4 minutes.
          2.  Immersion Consumption is 20 grams per 1 liter of technical water with temperature more than 20○C, hold on in solution within 10 minutes.
Note: solution to heat to 50○C for deoiling of metal in solid oil 50°C.
        Packing: polypropylene bags 40 kg each.
