| Fluorinated Anti-smudge Additive KY-1200 Series KY-1200 Series are UV/EB curable fluorinated acrylic compounds. When small amounts of KY-1200 Series are added to UV/EB curable acrylic hard coatings, surface properties such as water/oil repellency and anti-smudge effect can be added or enhanced. |

Features of KY-1200 Series Anti-smudge
A smooth fluorinated layer is formed on the surface and prevents stains with dirt. Removability of fingerprint
Persistent fingerprint can be removed easily by wiping. Water and Oil repellency
Repels water/oil and keeps substances clean. Low dynamic friction
Low friction makes wiping off easy and protects surfaces from scratches. |
