Samyang Inochem showcased its self-developed eco-friendly motor core adhesive for electric vehicles at the world's largest motor core exhibition.

Samyang Inochem, a chemical subsidiary of Samyang Group, announced on the 22nd that it presented research results on motor core adhesives using 'Isosorbide' at 'CWIEME (Coil Winding, Insulation and Electrical Manufacturing Exhibition) Berlin 2024,' held recently in Berlin, Germany.

The research presentation was conducted by Lee Chi-wan, head of the chemical research institute at Samyang. Under the theme "Toward Greener Mobility: Biomass-based Adhesives for EV Motor Cores with Excellent Adhesion and High Oil Resistance," the presentation highlighted the importance of adhesives for improving electric vehicle motor performance and shared performance data of the eco-friendly adhesive developed by Samyang Inochem.

In his presentation, Lee announced that using adhesives in the lamination method of electric vehicle motor cores is the most effective in reducing power loss and noise generation compared to the previously used fastening (Interlock) and welding methods. He then revealed test results of the eco-friendly adhesive developed using the eco-friendly material isosorbide, stating that its adhesion, thermal stability, and oil resistance?required for high-efficiency electric vehicle motors?are superior to conventional products, making it suitable for electric vehicle motor core manufacturing. He also introduced a 'self-bonding' adhesive technology for coating steel sheets, effective for manufacturing complex or small-sized cores.

Samyang Inochem set up a promotional booth at the exhibition and displayed three types of adhesives introduced in the research presentation. The exhibited adhesives include one-component and two-component adhesives, as well as adhesives for steel sheets. The one-component adhesive features enhanced adhesion and oil resistance, while the two-component adhesive allows room-temperature curing, unlike previous products that required high-temperature curing, and offers excellent storage stability, reducing costs and time during motor manufacturing. The adhesive for steel sheets is characterized by its customizability according to the type and application of the steel sheets. During the exhibition, more than 40 domestic and international motor core manufacturers and automotive parts companies visited Samyang Inochem's booth for meetings.

Samyang Inochem's electric vehicle motor core adhesives are currently mass-produced through domestic motor core manufacturers and applied to two domestic vehicle models, with plans to expand application to numerous domestic and international models this year.

Kang Ho-sung, CEO of Samyang Inochem, stated, "The motor core is the key to electric vehicle performance, and excellent adhesives are essential to reduce power loss and maximize efficiency." He added, "We plan to promote the excellence of Samyang Inochem adhesives through numerous domestic and international exhibitions and secure various partners, including new motor core companies, OEMs, and electrical steel manufacturers."

CWIEME, marking its 27th year this year, is the world's largest motor core-related exhibition, attracting motor core companies and steel sheet enterprises from around the globe annually. This year, over 600 companies participated, and the number of visitors reached approximately 6,000.
