Solder for use in electronics

Solder with our own rosin-based flux

Our flux technologies


Rosin is made by refining the sap (crude turpentine) of pine trees.

For more than 135 years since our company's establishment, we have been manufacturing various rosin-based products including printing chemicals, printing ink, tackifiers and adhesives. Our recent strategies focusing on the electronic industry are encouraging the development of rosin-based unique flux for electronic applications.
