Patinal® Water- and Oilrepellent Coating Materials for Displays

Smartphone or Tablet PCs with touch sensitive screens are part of our daily life. Only a screen without fingerprints allows an unlimited multimedia enjoyment.
The readability of touch panels rapidly degrades when fingerprints accumulate on the surface. Apart from the less attractive appearance this reduces the usability of the equipment. EMD Performance Materials Photonics has developed sophisticated materials that reduce the adherence of dirt and fingerprints on surfaces. Displays can be cleaned more quickly and the reduced surface friction makes them less sensitive to scratching. The smooth touch sensitive surface guarantees outstanding ease of operation. No need for protective films.
With its WR Patinal®  product range, EMD Performance Materials Photonics meets todays very high requirements of the smartphone and tablet PC touch panel market for anti-fingerprint, anti-smudge and easy-to-clean surface treatments.
