ALBERDINGK® LUX 220 VP
UV-curing PU-Dispersions for high demanding applications for:
• Pigmented furniture coatings
• On site UV
• Vinyl flooring
Challenges for UV-curing dispersions in pigmented coatings
• High UV reactivity in certain colours (yellow, orange,etc.)
• High chemical resistance (kitchen)
• High scratch resistance• High scratch resistance
• Good adhesion properties
Alberdingk‘s approach:
• Strong physical drying prior to UV-curing
• Scratch resistance as high as possible
• High resistances even in shadow areas

• High resistances even in shadow areas
• Safer handling of coated parts
• High UV-crosslinking density
