- Electronic materials and coating materials
Glass coatings and inks to provide coatings with variable reflectivity (high reflectivity, low reflectivity)
These products can be used to give high or low reflectivity to various types of displays and touch screens, contributing to their optical functionality.
By adjusting the refractive index of coatings and employing optical interference, these coatings contribute to optical functionally by enabling either high or low reflectivity.
MITSUBOSHI Hi-COLOR™ R, MITSUBOSHI Hi-COLOR™AR (High-reflectivityć»low-reflectivity type)
Benefits
- Screen printing and other types of wet deposition can be used to reduce cost.
- As entirely inorganic films, these products offer superior hardness, abrasion resistance, weatherability and heat resistance.
