Thermosetting Hard-Coating Liquid


Excellent scratch resistance

The liquids display hard coating properties during the steel wool test and Bayer test.

Excellent durability

The liquids show little deterioration from heat and light and cause little degradation in adhesion properties. They also have stability against various chemicals.

Excellent stability and preservation

Because of its excellent stability, the liquids can be transported and stored requiring no special conditions.
Note: They can be stored for two months when kept cold.

Application: Plastic Lenses
