Wet coating

Presenting new functional films through the combination of diverse film materials and pigments

What is wet coating technology?

Wet coating is a technology for uniformly coating base films with resins that are dissolved in organic solvents and liquids. The mechanism is similar to that for relief printing. In that process, the portion that will not be covered is recessed, the portion that will be covered is raised, ink is applied to the raised portion, and this is transferred to paper.

It is different from dry coating, which is used primarily for the adhesion of metals. Wet coating enables an approach to functional additions for objectives from every perspective by combining different resins and solvents. Therefore, the important issues for technicians are what materials (resins and solvents) to select, and how to combine them.

Advanced facilities supporting wet coating technology

  • Clean rooms

    We were the first in the industry to build the most advanced clean rooms to prevent the adhesion of dust and other impurities in the wet coating process. The cleanliness for our coating head sections is rated at Class 100 according to US federal standards, and Class 5 according to ISO and JIS standards. Our superior clean facilities meet the needs for rigorous cleanliness in the production process.

  • Processing equipment for 2,000 mm width

    Wet coated films are primarily used in width of 1,200 mm to 1,400 mm. We have processing machines capable for use with width of 2,000 mm. We respond fully to the customer requests for wide films, which have been increasing in recent years.

Functions added by wet coating technology and its uses

  • Hard coating

    This base function is added to that for wet coating, used for touch panels, electronic equipment, and furniture. It is a film that makes it difficult to damage the surface of electrical or construction materials, so it is applied to many products in everyday use.

  • Electrostatic charge prevention

    It is also an anti-static film to prevent the adhesion of dust to electronic products.

  • Easy adhesiveness

    It’s easy to understand if you envision the peel-off stickers on release paper. The film is the replacement for the paper, and is used for electronics materials.

  • Printability

    Films suited for printing

  • UV protectionInfrared blocking

    Films for attachment to auto and home windows to provide insulation, block light, and to prevent glass from scattering when broken

  • Anti-bacterial properties

    Films with an anti-bacterial function, with materials that restrict the growth of bacteria on kitchen sinks, the decorative boards in unit kitchens, and other locations

The future of wet coating technology

At present, our efforts are focused on enhancing our lineup of wet coated films and providing them with more new functions. These include items that prevent scratches and make fingerprints less visible, as well as items that are flexible and bend while maintaining their hard coat. Our customers want functions in addition to the hard coating, so we are developing functions that respond to those requests.

We offer new functional films that combine a diversity of film materials and colors and that accurately meet the needs of the times. That is our role, and we hope to contribute to Japanese craftsmanship in the future while employing wet coating technology.
