■What is a light-shielding film?

A light-shielding film is a coating film that blocks light. By coating a part with this film, light shining onto the surfaces of the part is diffused.

■Adoption example of the Light-shielding film

The light-shielding film is widely used for parts that should avoid reflection of light (such as lenses, apertures, and shutters of digital cameras and surveillance cameras, microscopes, and vision testers).

■What is a black lubrication coating?

A black lubrication coating is a black coating film that contains a solid lubricant in the coating film and therefore the surface has lubricity.

■Adoption example of the Black lubrication coating

The black lubrication coating is semi-matte coating film that blocks light. The coating is widely used for parts of cameras and digital cameras, such as body tubes and lens hoods.

■What is a matte coating for lens?

A matte coating for lens is a matte black coating film that prevents the diffused reflection of light. By applying this coating to the circumference of a lens, irregular reflection of light that occurs when the light transmits through the lens can be curbed.

■Main features

The coating can be applied using a paintbrush, brush, or sponge.

This coating can be baked at low temperatures. Even at normal temperatures, the coating solidifies by taking time.

*USE：Optics / Adapting for car / Monitoring camera&projector etc

*Material：Glass、Resin of PC etc

■What is electrostatic flocking?

Electrostatic flocking is a treatment method to plant finely chopped fiber (pile) in the surface of a base material vertically utilizing an electric field.

■Main features

The electrostatic flocking has the following effects: light blocking, non-slip effect, sound attenuation, decoration, heat insulation, prevention of chattering vibration sound, prevention of dampness, and velvet-like appearance and touch. This method is used for internal parts and lens hoods of cameras.

■What is a matte electrodeposition coating?

Matte electrodeposition is a method to deposit a matte black film electrically by applying a voltage of different polarities and a direct current to an electrode and an items to be coated, respectively with them immersed in paint. Our matte electrodeposition coating contains a composite high polymer emulsion.

■Main features

The coating has excellent weather resistance and can be applied to items in complicated shapes. It can be also used as an undercoat for painting.
