Synthetic Resins

Our history with synthetic resin products started in the printing ink field, which was the typical application for our core natural resin product of shellac. In trying to meet the needs of improving and developing the utility of conventional shellac, we learned about styrene grafted shellac emulsion as a shellac modification technic. Here is where we entered the field of synthetic resins.

Currently, we utilize various chemical reactions, from reactions at atmospheric pressure to applied pressure reactions; from bulk, solution, and suspension polymerization to emulsion polymerization and more, with a focus on radical polymerization reactions. We then apply functional polymers with functional groups to the central axis. The resultant graft polymers and various fine polymer materials have won the praise from customers and users for meeting their needs.

In terms of applications, we have a variety of resins available: pigment dispersion resin for water-based printing ink, let-down emulsions and resins for water-based overcoat varnishes. In addition to the printing field, we have also made advances in the electronic materials field, in the field of sizing agents for inorganic textiles, and the cosmetics field, etc., and we have received high praise from customers and users with all types of needs.
