KEY #3Able to transformed into any shape with high processing and highly adhesive coating

Products that can be applied to pre-coated metal can be molded even after coated.

Compatible with pre-coated metal systems

Good coating surface quality can be obtained with natural roll coating and reverse roll coating systems.

Molding and forming ability 

Excellent metal adhesion, processing followability, and hardness create a coating that can withstand complex molding processes after coated.

We want to aim such kind of co-creation!

In the period of changes in mobility market, co-creation of adding functionality through coating is required.
We aim to deliver polymer technology in any form.

What we can do for that!

A variety of functions such as metal adhesion, corrosion resistance, insulation, and hardness can be added to metal surfaces with complex shapes.
