| Résumé : |
Test methods for the continuous production control in the powder coating must deliver results as quickly as possible. In the following article important tests are rated for process monitoring in terms of significance to the user. |
| Note de contenu : |
- THE CURING PROCESS
- THE DSC ANALYSIS
- MECHANICAL TESTING
- NATURAL WEATHERING - FLORIDA/ ACCELERATED WEATHERING
- CORROSION TESTS : Alkali resistance - Condensation-water atmosphere / Resistance to moisture - Salt spray test - Filiform corrosion
- ELECTROCHEMICAL MEASUREMENTS
- TABLES : 1. GSB QR AL 631 modification from 1978 to 2016 - 2. Calculating the degree of crosslinking /1/degree of crosslinking (%) = (Tg film - Tg powder)/(Tg film fully crosslinked - Tg powder) *100

Curing curves for different material thicknesses - 3. Process of film formation - 4. Determination of the degree of crosslinking with DSC - 4. Determination of the degree of crosslinking with DSC - 5. Radiation intensity development in Florida from 1993 to 2013 - 6. Guideline values of GSB International for total UV radiation - 7. QUV-B test specifications and GSB requirements - 8. Test results RAL 9001 - 9. Loss of gloss for GSB master and premium systems after 5 years florida - 10K. Test duration of different corrosion tests - 11. Evaluation of corrosion tests regarding correlation, relevance, acceleration and precision - 12. Evaluation of the acidic acid salt spray test (AASS) regarding correlation, relevance, acceleration and precision - 13. Evaluation of the filiform corrosion test (FFK) regarding correlation, relevance, acceleration and precision - 14. Comparison of results according to 1000 hours FFK test (DIN EN 3665 : 1997) with 10 years of natural exposure in the maritime industrial climate of Hoek van Holland |
