Anti-reflective coatings eliminate stray light and enhance image contrast. This is ideal for various glass products such as LCD displays, telescope lenses, and optical lenses. Sukgyung AT's (low refractive index) hollow silica and magnesium fluoride effectively fulfill this function at a reasonable price. Due to their ultra-fine particle size, there is no reduction in transparency caused by fogging, which is common with other inorganic particle coatings. Depending on the application, these materials can effectively adjust the refractive index of the original material.

Anti-reflective coatings eliminate stray light and enhance image contrast. This makes them ideal for polarized films in various glass products such as LCD displays, telescope lenses, and optical lenses. Sukgyung AT's aluminum oxide, titanium dioxide, and zinc oxide (high refractive index) effectively enhance anti-reflective properties at a reasonable price. Due to their ultrafine particle size, there is no reduction in transparency caused by haze, which is common with other inorganic particle coatings. Depending on the application, these materials can effectively adjust the refractive index of the original material.

Sukgyung AT's ultra-fine tin oxide is expected to become an alternative solution to titanium dioxide, especially for the toner industry. On February 18, 2020, the European Commission (EC) announced regulations classifying titanium dioxide (TiO2) as a hazardous substance under the CLP Regulation No. 1272/2008 concerning the classification, labeling, and packaging of dangerous chemicals. TiO2 has been used in various industries, including cosmetics, toners, paints, and the electrical and electronic industries. In particular, since most printing toners contain a certain amount of powdered TiO2, alternatives with other chemicals are necessary to maintain the market. Sukgyung AT's ultra-fine tin oxide offers various surface treatments depending on your application. Please contact us for more details.

Plastic microbeads are very small, non-biodegradable solid particles. They are used in a wide range of products for cleaning purposes, such as cosmetics, toothpaste, abrasives, and exfoliants. Why is it important to prevent microbeads from polluting the environment? Microbeads can pass through the filters of wastewater treatment facilities during face washing or showering, and those that cannot be processed flow into rivers and oceans, potentially harming marine life, the global environment, and human health. We at Sukgyung AT would like to contribute to your business with our micron-sized spherical silica solutions.

At Sukgyung AT, we have developed spherical silica powder to save toner usage. By applying the spherical silica powder, manufactured using the sol-gel method, to toner particles, it is possible to significantly reduce toner consumption. Our spherical silica powder, which has already received positive feedback from many leading overseas companies, does not contain any elements subject to RoHS regulations. Furthermore, our research and development center offers optimal particle size adjustments and various surface treatments to meet the diverse needs of our customers.
