[INTRO] Where does innovation begin? With a force that moves everything, from unseen places. At KCC, it begins at the core. Built on technology and experience, we expand what’s possible. And we create solutions for a better future.
[BODY 1 - Company Introduction] KCC, a global advanced materials company representing Korea. Founded in 1958 as Kumkang Slate Industries, KCC has expanded its capabilities across four core businesses: building materials, coatings, advanced materials, and silicone. Built on these four divisions, KCC has led the development of Korea’s building materials and chemical industries. Today, working alongside global partners around the world, KCC contributes to innovation across architecture, lifestyle, automotive, electronics, and shipbuilding. Through these collaborations, KCC has become a trusted name across diverse industries. Beyond delivering products of outstanding quality, KCC deeply understands the needs of its partners and, grounded in technology and experience, provides solutions that drive shared success and growth.
[BODY 2 - Building Materials] KCC Building Materials respond to climate change by creating healthy, energy-efficient spaces. KCC windows minimize energy loss through high-performance insulation and airtight design, serving as a key element in zero-energy and eco-friendly certified buildings. In addition, Klenze, KCC’s high-end window, provides consistently comfortable indoor environments even amid changing outdoor conditions. It brings vitality to everyday life through the beauty of light and its gentle warmth. KCC Building Materials are developed using eco-friendly technologies, designed for both residential and office spaces. Insulation materials made from inorganic substances secure critical golden hour in the event of a fire, helping to protect precious lives. Eco-friendly gypsum boards with the highest HB Mark rating can be applied to create optimal indoor environments. From standard gypsum boards to fire-resistant, moisture-resistant, antibacterial, sound-insulating, and fully moisture-resistant solutions, they offer a wide range of functional options. In addition, premium ceiling materials that combine advanced performance with refined design complete the value of spaces, delivering both functionality and aesthetic excellence.
[BODY 2 - Coatings] KCC Coatings go beyond simply adding color to spaces. They evolve through technologies that protect the environment and enhance safety. As a leader in high-performance, eco-friendly water-based coating technologies, KCC Coatings extends beyond architecture and continues to expand across a wide range of industries. Through its dedicated research organization, KCC also advances the development of diverse, functional, and sophisticated color solutions. Marine coatings, developed alongside Korea’s shipbuilding industry, provide stable protection for vessels even in extreme marine environments while reducing frictional resistance to improve fuel efficiency. Automotive coatings deliver performance optimized for electric vehicles and the future mobility era, combining strong durability, refined appearance, and excellent scratch resistance. In addition, KCC offers fireproof coatings that prevent the spread of flames, automotive refinish coatings, and industrial coatings that enhance the durability of machinery and equipment. Today, KCC Coatings are evolving from Korea’s leading coatings brand into a trusted name in the global market.
[BODY 3 - Advanced Materials] Future industries driven by advanced technology begin with advanced materials. Across electric vehicles, AI, aerospace, and next-generation mobility, KCC focuses on the key materials that power advanced industries and accelerate technological innovation. From VI Ceramics, the global market leader, to ceramic substrates for power electronics, Korea’s first EMC developed for power modules, and glass fiber materials essential across a wide range of industries, KCC’s advanced materials technologies are shaping the foundation of the future.
[BODY 4 - Silicone] Covering sectors from lifestyle and industry to medical and aerospace, KCC has focused on the future value of silicone, a key material across virtually all areas of modern industries. With independently developed technologies, KCC became the first company in Korea to build a fully integrated value chain spanning from raw materials to secondary products. Leveraging this technological expertise, KCC has grown into a global leader in specialty silicone solutions.
[BODY 5 - R&D] Centered around its Central Research Institute and four specialized research centers, KCC is committed to advancing research in architecture, materials, the environment, and design, all in pursuit of a better life and a sustainable future. KCC is advancing AI-driven future technologies and self-driving coating robot technologies. Through research into core materials for future industries, including electric vehicles, aerospace, and semiconductors, and the development of eco-friendly materials and low-carbon technologies that proactively respond to global environmental regulations and carbon-reduction trends, KCC is anticipating the changes of the coming industrial era. Through these technological advances, KCC is elevating manufacturing processes, enhancing material performance, and raising the bar for sustainability across industries. In doing so, KCC is helping shape the standards of the future industry.
[BODY 6 - ESG] In addition, KCC is committed to realizing the values of a sustainable company. Across its corporate operations, KCC has introduced “Compliance Program 2.0” in line with global standards, reinforcing its commitment to values-based management and fostering a culture of transparency and ethical self-governance. In the environmental domain, KCC is pursuing carbon neutrality by 2050, expanding solar power generation, developing eco-friendly low-carbon materials, and prioritizing energy-efficient products as a core pillar of its mid- to long-term strategy. Through initiatives such as the “Firefly House,” “Saeddeul Maeul,” and the “Community Welfare Facility Environment Improvement Campaign,” KCC continues to deliver customized social contribution activities, leveraging eco-conscious, high-performance, eco-friendly products to create positive impact in local communities. In addition, KCC contributes to the growth of local sports culture through the operation of a professional basketball team. Through industry-academia collaboration and support for local community events, KCC is fostering a sustainable corporate culture, one that grows together with the communities it serves.

'Reverberation Time(RT)' is the time required for the sound in a room to decay over a specific dynamic range, usually taken to be 60 dB when a source is suddenly interrupted. Long reverberation times can create a cave-like echo effect, while short reverberation times can make sounds feel muffled, like in a recording studio. Therefore, different standards for reverberation time are used depending on the purpose of the space.
<Figure 1> Graph of the Acoustic Properties of a Space
The Sabine formula relates the RT to the properties of the room.
A = 0.161 
[㎡]
* By referring to the graph below, you can use different formulas depending on the purpose of the room and determine the optimal reverberation time based on the room's volume.
