After the last rinsing, drying inside the oven quickly removes the moisture remaining on the product.

Disassembly and cleaning. If you plan to paint a part that contains rubber bands, plastic, gaskets, wiring, then these elements will need to be removed, as they will melt when heated.
Removal of gases (degassing).Further preparation varies, depends on the type of metal, the condition of the current paintwork. If there is an old paintwork, then it can be removed with a special rinse, following the instructions.
Grinding / sandblasting.

Even if chemical flushing removes old paintwork well, it does not remove minor defects and rust. Therefore, sandblasting may be required.Cleaning after sandblasting. It is necessary to blow the dust with compressed air, then scratch the surface with a clean stiff brush, blow off the remaining dust again. Then gently clean with a clean towel with denatured alcohol. Then you can quickly walk with a torch with a propane burner, burning any remaining villi. Another option for cleaning the product from sandblasting dust is to immerse it in an acetone bath.

After that, it is placed in an oven heated to 200 degrees Celsius for 20 minutes. The powder sticks better when it hits a warm surface.As an additional step, phosphating or chromating can be used for absolute adhesion and durability. This is followed by rinsing and drying.Disguise. Some parts require masking before powder painting. All masking must be done in clean gloves, as this is the very last step before proceeding to powder painting.Hanging. The last step is to hang the object to be painted on a hook or wire.

Priming before powder coating

Thermosetting powder paints are usually applied to bare metal in one layer, without primer. Each subsequent layer “slows down” the static charge of the dry powder, promotes the formation of shagreen. The soil is usually an epoxy chemical composition. It enhances the adhesion of the subsequent layer, and can also serve as a filler (to smooth out the roughness of the substrate) or seals the porous cast metal from gas release.

There are certain types of powders that should not be combined with priming. The composition that gives the effect of wrinkles (wrinkles) should be applied directly to the substrate without primer. Otherwise, the primer will prevent the formation of wrinkles, thereby causing uneven finish coating.

The primer helps to extend the service life of the product and powder coating. The use of a primer is recommended if the product is operated under severe weather conditions.

To increase corrosion protection and increase adhesion, there are two main types of primers. One is without zinc content (ZINC FREE), the other is with zinc content (ZINC RICH). For ferrous metal (steel, iron), apply a primer with zinc, as it gives better protection. Aluminum is better primed with a primer without zinc content, otherwise there may be problems with adhesion, peeling.
