Powder Coating

The polyester powder coating on Aluminum extrusion offer an excellent protection and a wide range of color choice.

Special Polyester resins which have a proven record of corrosion protection and resistance against UV radiation are used along with binders and pigments.

The polyester powder is electro-statically sprayed on to the cleaned and chromated aluminum extrusions, then, thermally cured to produce the final product.

The polyester powder coating on aluminum extrusions produced at ALUTEX conforms to local and international aluminum finishing standards such as QUALICOAT.

Regular quality checks are made during production to ensure a high quality product as follows:

     A-    Pre-treatment : Prior to powder coating, the pre-treatment baths are regularly checked to ensure a clean chromated production.

     B-     Coat thickness :  Powder coat thickness on significant surfaces is checked by Eddycurrent instrument ( iso-scope ) to ensure a minimum of 60µm coat on exposed surfaces .

     C-     Gloss : Periodical  checks are made to confirm that gloss is  within a specified range .

       D-    Adhesion : Routine cross-hatch tests are done to

             confirm a good adhesion quality.

       E-     Elasticity : Routine tests are carried out such as

             bending and impact testing to confirm acceptable

             elasticity  of the coating.

     F-      Hardness :  Periodical tests are made to confirm the surface hardness of the coating .

     G-     Color : An international color code system is followed ( Ral code ).

H- Corrosion and Weather: Continuous tests in European Labs are made to check  the powder coating resistance to corrosion and different weather conditions.
