Material engineering

The best-choice coating born from our accumulated know-how.


The term “weatherstrip” literally means the sealing part which is exposed to all-weather conditions. Moreover, certain types of part will sustain a sliding effect by glass or sheet metal.
It is a tough job to secure and maintain the sealing property solely with rubber; the coating material to be applied on the seal surface also plays significant role.
We continue to develop the surface treatment material that matches with the product specific requirements using our accumulated know-how.
We are the early developer in the industry of a water-based material that is free from organic solvent, and most of the materials we used have been replaced with this material.
