Plastic Lens monomer


Easy to mold

It is possible to mold in the same manner as the CR-39 monomer.

Excellent surface workability

High performance is achieved by improved dye-affinity and combined use of TOKUYAMA hard coating liquid.

Excellent preservation stability

The monomer can be stored for 6 months at ordinary temperatures.

Excellent UV absorption properties

The monomer blocks UV.


Application: Plastic Lenses
