Dual-function paint cuts building energy use, tackles climate change

A new type of paint developed by Lee Yu CNC is offering a dual solution for energy efficiency and climate change mitigation. Dubbed "I-CELLENT," the paint acts as both an insulator against heat loss in winter and a heat reflector in summer. Residents of a South Korean apartment complex in Gumi experienced a cooler summer after the building's exterior was coated with the paint.

Following the application, the apartment's exterior walls saw a temperature decrease of 2.2°C on average, with a maximum drop of 15.3°C. Inside, temperatures fell by 1.6°C, leading to a significant reduction in cooling energy use, averaging 26.4% and reaching up to 40.8% in some cases. Lee Yu CNC CEO Choi Jang-sik highlighted that the paint's effectiveness stems from microscopic ceramic particles that block heat transfer and reflect infrared rays, enhanced by functional ceramic fillers for better adhesion.

By simply applying the dual-function paint once, we can solve insulation, heat reflection, energy saving, and carbon neutrality for the interior and exterior of buildings.

The company has received numerous certifications, including Green Technology and Eco-Label from the Ministry of Environment, and has been recognized by the Small and Medium Business Administration. Lee Yu CNC has also partnered with local governments on projects to apply the paint to low-income housing, improving living conditions and reducing energy costs for vulnerable populations. The technology, referred to as "cool roof," is gaining attention as a future solution for temperature control.

Beyond residential applications, Lee Yu CNC has tested the paint on large-scale infrastructure like factory storage tanks, railway tracks, and military facilities, demonstrating its ability to maintain stable temperatures, reduce storage costs, and improve operational efficiency. The company has also expanded internationally, proving the paint's efficacy in Indonesia and Malaysia, and plans to establish a joint production facility in Indonesia to supply the Southeast Asian market. Lee Yu CNC aims to become a global leader in climate crisis solutions, with plans for an Initial Public Offering in 2028.

Lee Yu CNC will grow into a company that helps solve the climate crisis and achieve carbon neutrality in Korea and the world.
