UV Spray Coating: Pioneering a New Era of Power Battery Safety<\/strong><\/p>\n

\"\"<\/p>\n

In response to the “strictest-ever battery safety regulations,Lankwitzer , a global leader in UV coatings, has developed a groundbreaking battery<\/strong><\/p>\n

insulation<\/strong>\u00a0technologyafter years of R&D tailored for BMW\u2019s power battery characteristics: UV Spray Coating. Compared to traditional PET foil, UV<\/strong><\/p>\n

\u00a0spray\u00a0<\/strong>coating offers\u00a0<\/strong>the\u00a0following advantages:<\/strong><\/p>\n

1. Performance Superiority<\/strong><\/p>\n

Stronger Adhesion: Post-curing shear strength reaches 16MPa.<\/p>\n

Higher Voltage Resistance: Withstands DC 6000V voltage testing without breakdown.<\/p>\n

Superior Thermal\/Humidity Resistance: Passes 85\u2103\/85%RH for 1000 hours.<\/p>\n

Excellent Flame Retardancy: Achieves UL94 V0 certification.<\/p>\n

Chemical Corrosion Resistance: Resists electrolyte erosion without swelling or delamination.<\/p>\n

2. Process Advantages<\/strong><\/p>\n

Simplified Workflow: Air spray application, eliminating cutting\/overlapping.<\/p>\n

High Efficiency: Single cell processing time \u2264 3 seconds.<\/p>\n

Strong Adaptability: Single production line supports variable cell sizes via parameter adjustments (spray gun, line speed).<\/p>\n

Easy Rework: Defective cells require only 3\u20136 seconds for laser paint removal at a single workstation.<\/p>\n

High Yield Rate: First-pass quality rate reaches 99.5%.<\/p>\n

With the implementation of China\u2019s GB 38031-2025 standard, the power battery industry is undergoing a profound safety transformation. Traditional<\/p>\n

PET foil struggle tomeet the demands of high-voltage platforms (800V\/1000V) and CTP\/CTC battery structures. UV spray coating, with its 16MPa adhesion,<\/p>\n

6000V+ voltage\u00a0resistance, UL94\u00a0V0 flame retardancy, and >99.5% yield rate, has become the preferred insulation solution for next-gen power batteries.<\/p>\n

Technological Upgrades Drive Industry Reshuffle<\/strong><\/p>\n

The “zero-tolerance” safety requirements of the new standard will accelerate the elimination of SMEs reliant on traditional blue films, while pushing industry<\/p>\n

leaders (e.g., CATL, BYD) to adopt UV spray coating rapidly.<\/p>\n

\u00a0Collaborative Innovation Across the Industrial Chain<\/strong><\/p>\n

From materials (e.g., Lankwitzer\u2019s high-performance UV coatings) to equipment (Steelmaster\/Stema UV spray lines) and vehicle integration (BMW\/BYD’s<\/p>\n

high-voltage\u00a0platforms), UV spray coating is forming a complete industrial ecosystem, elevating China\u2019s battery safety standards to global leadership.<\/p>\n

Future Outlook<\/strong><\/p>\n

Post-2026, “no fire, no explosion” will become standard for NEVs. UV spray coating, with its high safety, cost efficiency, and green manufacturing advantages, is<\/p>\n

poised to\u00a0dominate battery insulation, enabling higher energy density, faster charging, and longer lifespans.<\/p>\n

The new standard represents not just a safety upgrade but a technological revolution. UV spray coating marks the transition of power batteries from<\/p>\n

“passive protection”to “active safety”, laying a solid foundation for global NEV adoption. As the technology evolves, China’s power battery industry will continue<\/p>\n

leading\u00a0the\u00a0world in both\u00a0safety and performance.<\/p>\n
