Revolutionary Upgrade in Coating Materials for Power Battery Packs: From PET Blue Film to UV Coatings
Traditional PET blue films, limited by their low bonding strength (0.5–2 MPa) and inadequate pressure resistance, are gradually being replaced by UV coating materials. Lankwitzer UV coatings, formulated with a solvent-free composition, achieve curing in just 2 seconds and demonstrate over 50% improvement in insulation performance. BMW has pioneered the adoption of Lankwitzer’s UV coating technology, while domestic industry leaders such as CATL are accelerating their transition to this advanced solution.
With the superior performance advantages of UV coatings becoming increasingly evident, these materials not only significantly enhance bonding strength—surpassing traditional PET blue films to reach levels exceeding 12 MPa—but also improve pressure resistance, ensuring the stable operation of electronic components in high-intensity, high-voltage environments. This technological breakthrough not only addresses the urgent demand for lightweight, high-performance electronics but also lays a solid foundation for future applications in high-end sectors such as new energy vehicles, 5G communications, and aerospace.
As a leader in the automotive industry, BMW’s early adoption of Lankwitzer UV coatings has set a benchmark, driving the widespread application of these materials in automotive manufacturing. Following suit, domestic power battery giants like CATL are actively responding to market and technological shifts by accelerating R&D and deployment of UV coating technology. This aims to enhance the safety and reliability of battery packs through innovation, further solidifying their leadership in the global new energy market.
Moreover, the eco-friendly attributes of Lankwitzer UV coatings—particularly their solvent-free formulation, which drastically reduces volatile organic compound (VOC) emissions—align with increasingly stringent global environmental regulations and provide robust support for corporate green sustainability initiatives. As the technology matures and costs decline, Lankwitzer UV coatings are poised to replace traditional materials across a broader range of industrial applications, ushering in a new era in materials science.
