Resistance to boiling water- Qualicoat Testing
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 …

Electrostatic Painting Process
Electrostatic painting is a process in which a spray gun tip is electrostatically charged; making the paint charged electrically; thereby allowing the paint to be attracted to a grounded surface. This process wastes almost no paint through normal air flow, wind, or dripping. This is because the paint particles are actually attracted to the surface you are painting like a magnet. However, in order for the process to work the object you are painting has to be grounded. Electrostatic sprayingRead More …
Accelerated weathering test for Qualicoat
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 …

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 …
Tape Test for evaluating coating adhesion
By far the most prevalent test for evaluating coating ”adhesion”is the tape-and-peel test, which has been used since the 1930’s. In its simplest version a piece of adhesive tape is pressed against the paint film and the resistance to and degree of film removal observed when the tape is pulled off. Since an intact film with appreciable adhesion is frequently not removed at all, the severity of the test is usually enhanced by cutting into the film a figure XRead More …
Rapid Testing Methods for Production Control
For some years now, special time-compressed corrosion tests based on recommendations made by European quality associations have become more established. The following are worthy of mention: condensation test, acid and neutral salt spray test, filiform corrosion tests and specific automotive test standards. Despite the demand to speed up tests, testing times of between 40 and 60 days are typical, thus rendering the tests irrelevant as far as real-time production control is concerned. In this regard, rapid innovative corrosion tests areRead More …
