A new UV-curing polyurethane dispersion specifically developed for coating mobile phones and other high-quality electronic devices can keep these products looking like new for much longer, according to Bayer MaterialScience (Leverkusen, Germany), which developed and markets the new coating.
Solvent-free, the Bayhydrol UV XP 2689 coating is comparable to the Bayhydrol UV coatings the supplier already markets for wood and furniture coating.
According to the supplier, the crosslinked molecular structures created through UV radiation curing help ensure resistance to, for example, hydrolysis and cosmetics, and also bring scratch- and abrasion-resistance to the party.
The dispersions work as clear coats for leveling any surface roughness of the basecoat, or can be used as one-coat systems to produce an opaque metallic effect. —[email protected]
