Preparation and Coating
The raw aluminum surface receives a traditional pretreatment of a chemical conversion, creating a thin layer of amorphous oxide with coating. Electrostatic guns then apply a 2.5 mils layer of nonhazardous powder paint. The polymerization is done with a 400°F temperature for 20 minutes. The base coat ensures adequate hardness of the final product, and protects the aluminum from light, weather, abrasion, corrosion and humidity.
Decoration A preprinted film transfer with organic photosensitive pigments and cellulose resin is completely wrapped around the product. The profile is positioned on the surface of a movable trolley, and air is removed through a vacuum suction system. The result is a perfect thermoprint. The trolley is then placed in a special oven, where the decoration is effected, turning the ink pigments from solid into gas and back to solid inside the paint layer. After cooling, the film is removed. Combined with other breakthrough technologies we apply to the endeavor, this process accounts for why Decoral System is a global leader in color coating quality.
Decoral System adheres to stringent product standards, and we have earned the AAMA certificates and Qualicoat label, acknowledged by the European Laboratory and Research Organization. Backed by a comprehensive warranty and certified for both indoor and outdoor applications, our coatings rise to the highest standards of performance excellence and design innovation. Our exacting quality-control regimen includes these state-of-the-art procedures:
* Stereoscope observation * Microscope test with infrared rays * Electronic scan microscope test * Valuation of the brightness, thickness, adherence, hardness * Embossing test, impact resistance, accelerated corrosion test * Resistance to salt-acid room, accelerated aging test * Lime resistance test, boiling water resistance test, condensed water resistance test * Cutting, milling, drilling, flaring, slicing analyses
