Generally speaking, paints consist of resins, additives, coloring agents (pigment), and solvents. The resin is the main element in paint which dries to form a film. Polyester, epoxy, acrylic, urethane, and silicone are used.
We manufacture solvent based acrylic and urethane resins. Acrylic resin has translucent and weather resistant features. Urethane resin is flexible and can be used as a top coat for various plastic products, as an outdoor ink, and as a vehicle for paints, primers, and adhesives.
We also handle special resins with special features such as a silicone denatured acrylic resin that incorporates ladder silicone as a main frame.

The Hi-Coap AU series is UV-setting resin developed from TOKUSHIKI's unique technology. This UV-setting resin has low-pollution, energy-saving, and high-productivity qualities. It needs very little energy to dry because of its short hardening time, compared with resins that harden by heat or with constant temperature hardening systems. We are developing UV-setting resins that use urethane acrylate as their main ingredient.

Urethane acrylate forms a tough, flexible layer that offers excellent adherence to base materials. The layer consists of polyol, isocyanate, and acrylate, as shown in Figure 1 below.

The physical properties of a urethane acrylate hardened object depend upon the design of the polyol, the type of isocyanate used, and the number of acrylic groups. Therefore, urethane acrylates are designed by changing these factors to offer different characteristics which will match each application. Some combination of these factors will produce a resin with suitable physical properties such as hardness, elongation level, and adherence to a base material. Since it can be used to denature other resins, it may be possible to use a urethane acrylate where it is not possible to use a normal urethane resin.
