In general, coating agents qualified to be “functionalizing” add various capabilities to the articles to be coated.
Such capabilities include optical, electric/electronic, mechanical/chemical, and environmental capabilities.
●electric/electronic capabilities: antistatic capability, conductivity, electromagnetic shieldability
●Mechanical/chemical capabilities: Elasticity, water repellency and antifouling and antibacterial capabilities
●Environmental capabilities: photocatalytic activity
Antifouling Coating agents
The coating agents are made from silicone-modified acrylic resins that have ladder silicone (polysiloxane/silsesquioxane featuring a ladder-type structure) incorporated into their molecular skeletons. They have more durable water repellency than antifouling coating agents containing only conventional silicone additives.
In addition to a silicone-modified acrylic structure, fluorine-based coating agents are also available.

| TKA-270 | Hard coating agent with a pencil hardness of F and an elongation of 150% |
| TKA-370 | Soft coating agent with a pencil hardness of B and an elongation of 400% |
| UVTKA-520 | Hard coating agent with a pencil hardness of 2H and a pre-UV-curable elongation of 230%. It has better curling properties than solvent-based or solventless UV-curable hard coating agents. |
Black AG coatings(under development)
- By adding a small amount of special carbon, it improves the concealability of the inside while maintaining transparency and antiglare property.
- Because of its flexibility, it can be applied to urethane-based films.Flashlights with curved surface shapes, as well as light-emitting and display devices with enhanced design and anti-glare properties, can prevent damage and deterioration of the light source cover.
Anti-fog coatings(under development)
・ Due to the thermosetting type, it is possible to add various fillers to the coating film.
・ Due to its self-healing property, it is superior in scratchability to similar acrylic paint films.
・ Due to the low contact angle with water, water spreads on the coating film without water droplets.

Zirconium Oxide High Refractive Index Coatings(under development)
- Since the ratio of zirconium oxide is about 80% in terms of resin ratio, a high refractive index can be expected.
- Various properties can be imparted depending on the type of filler such as resin and metal oxide to be added.
- Excellent handling due to high filler concentration and low viscosity.
