The Polyester Powder is Electro-statically sprayed on the cleaned chromatic Aluminum Extrusions. Then, it is thermally cured to produce the Final Product, following standards such as QUALICOAT, DIN, BS, ASTM, and ISO.
-
Anodic Coat Thickness on Significant Surfaces is checked by current instruments (PERMASCOPE / ISOSCOPE) according to DIN 1615 and ISO 2360.
-
Significant Surfaces of Extrusions are checked out to ensue that the surface is free from mechanical and Metallurgical Defects.
-
Sealing (Stability) test is done by measuring the admittance value “Y” according to DIN 50949, BS 1615, and ISO 2931.
