Recently, KCC, a global applied materials chemical company, developed a UV-curable high-refractive index coating technology suitable for plastic (PET) for the first time in Korea, and completed a patent application.
The technology introduced this time uses automatic roller coating equipment to carry out continuous roller coating on the surface of the material, which has faster speed, shorter drying time, higher production efficiency, thin coating and uniform coating, and can be designed in various colors to reflect the product. high-level sense.
At present, the main technology used in the market is to heat and evaporate the metal or compound, so that its vapor forms a thin film on the surface of the object. Due to the expensive equipment used, it is difficult to ensure mass production of products, so it is only applicable to some color products, but the technology developed this time overcomes this limitation.
In the drying process, the chemical reaction of the coating is promoted by ultraviolet curing technology, and the coating film is cured in a short time. Titanium dioxide (TiO2), ensuring safety.
KCC started the plastic coating business in 2015, established production bases in China and Vietnam in 2016, and gradually developed domestic and foreign markets. Specially developed pollution-resistant soft-touch coatings, which are suitable for various wearable products such as smart watch straps and wireless earphones, and launched coatings for electronic cigarettes to seize market opportunities; in addition, KCC’s high-quality environmental protection and functional coatings are expanding their applications In the field of AI audio and home appliances, this technology will also be applied to the latest mobile phones in 2023.
A person from KCC said, “This achievement is of great and far-reaching significance in response to the rapidly changing mobile terminal market trends and the development of domestic independent research and development technology. KCC will further strengthen its strength based on the technical strength of this development to ensure that Improve the market competitiveness that can be applied to a variety of materials and products, and continuously create higher quality and brand trust.”
