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…)
