Anti-blocking agent

Our products are used as anti-blocking agents for transparent films and anti-sticking agents for transparent tare bags. At the same time, our products contribute to speeding up customers' processes (improving slippage and rewindability) and reducing masking.

Our Features

  • Anti-blocking agent composed of ultra-fine particle materials.
  • It is applied as an anti-blocking agent for polarizing film which requires high transparency.
    • A wide variety of particle surface designs are available to adjust the compatibility with coating agents and the surface ubiquity of particles.
    • Available in a wide range of media, including various solvents and low-viscosity monomers.

    Hard Coat Related Products (Abrasion Resistance)

    These products are used to increase the hardness and abrasion resistance of clear hard coatings used in decorative films and optical discs.In recent years, the market has been expanding to flexible displays and 3D displays. Recently, there has been an increase in applications for surface coating of flexible displays and 3D moldable films.

    Our Features

    • Products composed of ultrafine particle materials.
    • It can be used without interfering with the transparency of the coating film.
    • The surface of the particles is designed (functional groups are added) according to the resin of the coating agent.
    • We can provide products dispersed in various media, such as various solvents and low-viscosity monomers.
