9. Applications
Superior technical properties of Tinuvin® 5333-DW vs. classical BTZ and alternative
UVA technologies for WB systems allow multiple potential applications:
 Wood coatings (clear and light pigmented coatings for natural and stained wood,
indoor furniture and flooring, joinery and many exterior wood finishing applications)
 General industrial paints (i.e. WB 2K-PUR clear coats)
 Plastic coatings (PC and PMMA sheets, panels, plates, foils, liners, tarpaulins…)
 OPV (graphic arts, printed goods, decals, signs…)
 Coatings for glass (architectural glazing, packaging materials)
 Architectural coatings (roofing, flooring, walls…)

10. Test results - joinery
 Main industry:
joinery (decking)
 1K WB acrylic dispersion:
Acronal® LR 9014
 Accelerated weathering test:
Q-UV (EN 927-6):
 Colour deviation (∆E*)
 60 ° gloss retention
Xe-WOM (DIN 4892-2):
 UVA retention
