Qualicoat Test

All organic coatings except class 2 and 3 powder coatings: EN ISO 1519 Class 2 and 3 powder coatings: EN ISO 1519 followed by a tape pull adhesion test as specified below: Apply an adhesive tape to the significant surface of the test panel following the mechanical deformation. Cover the area by pressing down firmly against the coating to eliminate voids or air pockets. Pull the tape off sharply at right angles to the plane of the panel after 1Read More …

Method 1 with boiling water: 2 hours immersion in boiling demineralised water (maximum 10 μS at 20°C). Remove the test sample and allow it to cool down to room temperature. Apply an adhesive tape (see § 2.4) to the surface, ensuring that no air is trapped. After one minute, remove the tape at an angle of 45° with a sharp even pull. Method 2 with a pressure cooker: (to be used for powder and electrophoretic coatings only) Add demineralised waterRead More …

EN ISO 11341 Luminous intensity: 550 ± 20 W/m2 (290 – 800 nm) Black standard temperature: 65 ± 5°C Demineralised water: maximum 10 μS Special UV filter (290 nm) Cycles of 18 minutes in a wet medium and 102 minutes in a dry medium. After 1000 hours exposure (2000 hours for class 3), the test panels should be rinsed with demineralised water and checked for: Gloss variation: EN ISO 2813 angle of incidence 60° Colour change: ΔE CIELAB formula according toRead More …

(for powder coatings only) The impact shall be carried out on the reverse side, whereas the results shall be assessed on the coated side. -Class 1 powder coatings (one- and two-coat), energy: 2.5 Nm: EN ISO 6272- 2 (indenter diameter: 15.9 mm) -Two-coat PVDF powder coatings, energy: 1.5 Nm: EN ISO 6272-1 or EN ISO 6272-2 / ASTM D 2794 (indenter diameter: 15.9 mm) -Class 2 and 3 powder coatings, energy: 2.5 Nm: EN ISO 6272-1 or EN ISO 6272-2Read More …

Exposure in Florida according to ISO 2810 , The natural weathering test should start in April. Class 1 organic coatings Samples shall be exposed facing 5° south to the horizontal and facing toward the equator for 1 year. 4 test panels per colour shade are required (3 for weathering and 1 reference panel) Class 2 organic coatings Samples shall be exposed facing 5° south for 3 years with an annual evaluation. 10 test panels per colour shade are required (3 per yearRead More …

Test Methods and Requirements The test methods described below are used to test finished products and/or coating systems for approval (see chapters 4 and 5). For the mechanical tests (sections 2.6, 2.7 and 2.8), the test panels must be made of the alloy AA 5005-H24 or -H14 (AlMg 1 – semihard) with a thickness of 0.8 or 1 mm, unless otherwise approved by the Technical Committee. Tests using chemicals and corrosion tests should be performed on extruded sections made ofRead More …
