Application Of Optical Coating Zinc Sulfide in Optical Coating Materials
Leave a message
The high-purity Optical Coating Zinc Sulfide S-30, produced by Yunfu Hongzhi New Material Co., Ltd., is a white functional material. It possesses a refractive index of 2.37, high thermal conductivity, a Mohs hardness of 3.0, and remarkable dispersibility. It exhibits resistance to corrosion within the pH range of 4 - 12 and is insoluble in water and solvents. Owing to its relatively low Mohs hardness, it can offer certain wear resistance. With its high purity and absence of trace elements, it finds extensive applications in a variety of fluorescent materials, coating materials, plastics, rubber, paints, inks, and paper.
1. Optical Coating Zinc Sulfide S-30 is an outstanding infrared optical material and an essential raw material for the manufacturing of infrared imaging devices. It can be utilized to fabricate infrared imaging devices with high infrared transmittance and excellent optical uniformity, thereby enabling the acquisition of high-resolution, high-definition infrared imaging with minimal image distortion. In the military field, Optical Coating Zinc Sulfide can be applied to produce infrared windows and visors.
2. Optical Coating Zinc Sulfide is used for optical coatings, manufacturing anti-counterfeiting labels for laser coatings, mainly for anti-counterfeiting labels on currency, ID cards, and passports; and anti-counterfeiting marks on cigarette, alcohol, and pharmaceutical outer packaging.
A thin layer of Optical Coating Zinc Sulfide is coated on the surface, forming a Optical Coating Zinc Sulfide coating. Due to the high refractive index of Optical Coating Zinc Sulfide, the plastic film surface exhibits a metallic luster. This Optical Coating Zinc Sulfide coating not only has a metallic luster, but also can produce a strong, bright, and colorful light pattern effect under light irradiation, significantly enhancing the grade of printed products. For example, in the application of high-end printed products with paper-plastic composites, the Optical Coating Zinc Sulfide coating can be used after printing to create a high-end integrated holographic color-printed paperboard packaging, such as cigarette boxes, daily chemical product packaging, food packaging, and gift boxes. These packages exhibit a strong, bright, and colorful light pattern effect under light irradiation, enhancing the appeal and competitiveness of the products.
Optical Coating Zinc Sulfide coatings have an angle-dependent color effect. Under the condition of changing the incidence angle, the light changes with the angle, causing a shift in the reflection spectrum, resulting in a color change effect with the change of the observation angle.
3. Optical Coating Zinc Sulfide is also used to manufacture luminescent powders, mainly used for emergency evacuation signs, highway signs, and other luminescent signs.
