Decoral System. Bologna 19-05-2011 - Aluminium 2000

  1. 1. METAL DECORATION BY DECORAL® TECHNOLOGY SUPERDURABLE WOOD GRAIN Alessandro Canevarolo Bologna, 19 maggio 2011
  2. 2. Wood Grain - Comparative test Wood EffectSublimation Process (Heat transfer) on coated metal surface
  3. 3. Sublimation Process (Heat Transfer)Phisical process by which some substances at given temperature move directly from solid to gas status.Sublimatic ink supportSublimatic ink (dyes)Powder coating layer 200°C Aluminum Sublimatic ink substrate Printed Sublimatic ink (dyes) Powder coating layer Aluminium
  4. 4. Used Raw Materials- Polyurethane Powder Coating- Heat Transfer Film(printed with sublimatic Ink)
  5. 5. Sublimation Process Advantage High print definition
  6. 6. Sublimation Process AdvantageSuitable to be applied to different shapes
  7. 7. Wood Grain Comparative testsWood Grain on Superdurable PUR Powder vs Wood Grain on Standard PUR Powder
  8. 8. Superdurable Polyurethane Powder Series DS 04XX S & Series DS 07XX SNew formulation of powder coating including: - special resins - special combination of UV inibhitors
  9. 9. Samples Preparation Powder Coating + Decoral Process- Powder coating, carried out in compliance with TDS temperature and time (20@ 200°C)- Decoration according to sublimatic film TDS (peak temperature 200°C)
  10. 10. Obtained Samples Two series of samples- A1, B1, …, N1 serie made by Superdurable powder coating (green line)- A2, B2, …, N2 serie made by Standard powder coating (red line)
  11. 11. TestsAccelerated Weathering Test – AWT- Decoral Laboratory- Controlled and repeatable- simulation of some natural exposure factor- 3000 hours durationNatural Exposure Test – NET- South Florida (AWSG)- Real enviroment- Unpredictable test- 12 months exposure
  12. 12. Accelerated Weathering TestDecoral Laboratory ISO 11304 - irradiation, 550 ± 20 W / m 2 (290-800 nm) - black panel temperature, 65 ± 5 ° C - wet cycle 18 minutes - dry cycle 102 minutes.
  13. 13. Accelerated Weathering Test Evaluated Parameter every 100 hours until 3000 hours- Residual gloss % (60° angle, ISO 2813)- Colour Variation (ΔE CIELAB, ISO 7724/3)
  14. 14. AWT – Residual Gloss%Remarks: 3000 hours are 3 times minimum required by international specification
  15. 15. AWT – Residual Gloss% Superdurable serie (DS 07XX S) - Residual gloss % of Superdurable wood grain > 80% @ 3000 Hours - Residual gloss % of Standard wood grain > 50% @ 1000 HoursRemarks: 3000 hours are 3 times minimum required by international specification
  16. 16. AWT – Colour VariationRemarks: 3000 hours are 3 times minimum required by international specification
  17. 17. AWT – Colour Variation Superdurable series (DS 07XX S) - ΔE of Superdurable wood grain < 2 @ 3000 Hours (all pattern!) - ΔE of Standard wood grain < 2 @ 1000 HoursRemarks: 3000 hours are 3 times minimum required by international specification
  18. 18. AWT – Tested Samples – 3000 h Tested Samples D1 D2(superdurable wood grain) (standard wood grain) Remarks: 3000 hours are 3 times minimum required by international specification
  19. 19. AWT – Tested Samples – 3000 h Tested Samples I1 I2 (superdurable wood grain) (standard wood grain)Remarks: 3000 hours are 3 times minimum required by international specification
  20. 20. Natural Exposure Test ATLASWeathering Service Site ISO 2813 - - south Florida site - - 12 months exposure  - facing south  - tilt angle 5°  - open backing
  21. 21. Natural Exposure Test – 12 months Evaluated Parameters(after 12 months exposure & cleaning process) - Residual gloss % (60° angle, ISO 2813) - Colour Variation (ΔE CIELAB, ISO 7724/3)
  22. 22. NET – Residual Gloss%
  23. 23. NET – Residual Gloss%- Residual gloss % of Superdurable wood grain > 90% after 12 months exposure- Residual gloss % of Standard wood grain > 50% after 12 months exposure
  24. 24. NET – Colour Variation
  25. 25. NET – Colour Variation- ΔE of Superdurable wood grain < 2 after 12 months exposure (all pattern!)
  26. 26. NET – Exposed Samples – 12 months Unexposed part D1 D2(superdurable wood grain) (standard wood grain)
  27. 27. NET – Exposed Samples – 12 months Unexposed part I1 I2(superdurable wood grain) (standard wood grain)
  28. 28. Conclusions- Excellent results are linked to a new formulation experience- Superdurable series (DS 04XX S & DS 07XX S) levels up the weathering resistance- Performance improvement for a wide range of finishing (different wood grain)
  29. 29. Future- Expand the exisiting market for heat- transfer technology- Open new fields of application- Complying with more strict requirements
