Feature of KarenzBEI®

The characteristics of KarenzBEI®
Our customers are satisfied with the present Karenz series which characteristics are below.

・easily introduce UV-curable properties in a molecules
・easily reacts with functional molecules

Karenz series

We develop the new material, KarenzBEI ,
in order to meet customer’s expectation.

The new product, KarenzBEI , has one isocyanate
group and two acrylic groups in one molecule,
ensuring higher performance!

・Higher UV curing speed
・Stronger adhesion to a substrate
・Less shrinkage at the curing

The UV curing speed of KarenzBEI is very high because it has two acrylic group in it’s molecular structure.

The adhesion strength of to substrate (glass, metal, PET resin, etc.) is very high.

For Use
KarenzBEI is available for the following areas because of its high UV reactivity.
 ・ Photo resist ( film resist, color resist, liquid resist)
 ・ Surface modification, Adhesive, Printing, Paint coating

*This product is only for industrial usage. Please make contact with us if you think other usage.
