PAINTING CYCLE<br />
The paint finish in carried out by a continuous automatic system which passes trough the following phases:<br />
- Washing and desgreasing with an iron-phosphate degreaser at a temperature of <strong>55</strong>°C.<br />
- Slucing down with a passivating substance in two stages to complety clean all surfaces and provide a base for the finish.<br />
- Oven-drying at 120°C<br />
- Painting in a rodotized cabin (wich garantees the uniformity of thisckness of the film) with varnishes in exposy-poliestr heat-drying powders applied<br />
electrostatically.<br />
- Polymerization in an oven for about 18 minutes at 190°C<br />
