- Polyester (PE-F) powder coating.
- Super Durable (PE-SDF) Powder coating
- Durasol Powder coating
- Cool Shade Powder coating
- Wood coatings.
- PVDF Kynar coating.
Wet Coatings:
- Enamel – based coatings
- Epoxy Coatings
- Polyurethane Coatings
- Zinc – rich Coatings
Coating procedure consists of the following stages: –
- Chemical pre-treatment process consisting of 7 steps, these are:
- Water rinsing 1 no.
- Acid itching/degreasing tank 1 no.
- Water rinsing 1 no.
- Chrome Free rinse 1 no.
- Water rinse 1 no.
- DI water rinse 1 no.
- Heating dryer 1 no.
- Powder application: After drying off the material it is directly sent for powder coating through an automatic powder spraying booth supported with 10 advanced GEMMA super corona guns to get the perfect powder finish on the material or coated with PVDF(Kynar) coating facility consists of four booths
- After powder coating the substrates, go through curing oven at a temperature of 210 degrees CO for 10-25 min, According to the powder specification.
- The final process is to ensure the quality of the products through visual inspection and laboratory tests according to the Qualicoat standards, upon completion of the tests, packing process is done with polyethylene film to protect the coating in the finest manner.
Our Quality Control Procedure:
- Color Comparison: To insure the color matching with the reference samples
- Gloss test: According to ISO 2813 (using incident light 60 degrees), then compare the results with the required
- Film thickness: According to ISO 2360, this test is done by using film thickness gauge to ensure the film thickness in a range of (60-90 microns)
- Adhesion test: According to ISO 2409, by using cross hatching cutter with 2mm and 3mm blades gaps to insure the adhesion between powder and substrates
- Pencil hardness test: According to ISO 15184, by using pencils with various harness values to insure scratching
- Impact test: According to ISO 6272 by using impact tester to insure the coating resistance for impact action without
- Bending test: According to ISO 6860, by using conical mandrel to ensure the flexibility of the coating when bending action happens.
- Polymerization test: By using solvents to insure the curing process for the coating
- Boiling water test: A deep cross is made on the coated panels made for testing purposes and submerged in boiling water for 2 hours, upon completion the panels are taken out to check the powder adhesion quality on the material.
Advantages
Advantages of Powder Coating
-
- A thick layer can be applied in one process (50-200 micron).
- The finished result guarantees uniform surfaces.
- Suitable for outdoor use – good resistance to UV and corrosion
- A beautiful and uniform quality finish without paint runs
- Cost efficient – even on small batches or single items
- The electrostatic powder process ensures complete coverage – even on complex shapes
- Choice of finishes – clear, plain color, metallic or textured
- Exceptional gloss and color retention
- Robust mechanical and chemical performance – good at resisting abrasion, acids, solvents etc.
- Good electrical insulation capabilities
- Contains no Volatile Organic Compounds (VOC’s)
Advantages of Wet Coating
- A very elegant appearance / finish can be achieved.
- Wet coating is very suited for materials to appear multi-colored.
- Very long outdoor life if the correct layer thickness is chosen.
- Materials with holes down to and including 1.0 mm diameter can be wet coated. (If the holes are smaller than 1.0 mm further investigation is required)
