SHIN-ETSU SUBELYN®
Fluorinated Anti-smudge Additives
KY-1200 Series
KY-1200 Series are UV/EB curable fluorinated compounds. When small amounts of KY-1200 Series are added to UV/EB curable 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.
- Durability against scratches
- Protects surfaces from scratches.
- Low refractive index
- Low refractive layer is formed
when increasing the amount of the contents.
It can be used for Low Refractive (LR) materials.

Operating information
- Hazy mixture may depend on choice or mixing ratio of hard coating and thinner.
- By adding KY-1200 Series, curing speed of hard coating may change.
In case of insufficient cure, modify curing conditions. - The effect of the coating with KY-1200 Series may change depending on curing atmospheres even if they have the same components. We recommend to irradiate with UV light under the inert gas atmosphere for the best result.
- KY-1200 Series easily dissolves in ketone-based, ether-based, ester-based and fluorine-based solvent but doesn’t dissolve easily in hydrocarbon-based solvents and alcohol-based solvents.
- It may change compatibility and stability depending on mixing ratio of hard coating.
Please test under your conditions.
Application process
Applications
When small amount of KY-1203 is mixed with UV/EB curable compound, fluorinated chains are distributed on the outer surface, then anti-smudge, water/oil repellency, fingerprint removability and low dynamic friction are realized.
- Hardcoated film
- Anti-reflective film
- Displays
- Touch panel
- Electronic device housing
- Decorative film
Operational Infomation
Strorage
