SHIN-ETSU SUBELYN®
Fluorinated Anti-smudge Coating KY-100 Series
KY-100 Series are coating materials consist of organofluorine group and reactive silyl group. When very thin coatings with KY-100 Series are applied onto various substrates, excellent surface characteristics are obtained.
Features of KY-100 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.
- Durability against scratches
- Protects surfaces from scratches.
- Very thin layer
- Preserves substance’s optical properties and texture.
