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
