PET vs. UV Coating: Lankwitzer’s ISO-Certified Solution Dominates High-Voltage EVs

In 800V systems, where PET films fail due to voltage breakdown and moisture ingress, Lankwitzer’s UV coating introduces self-healing microcapsules that activate upon impact. These capsules release ceramic-forming agents, creating a protective layer within 0.1 seconds to suppress arcing. Porsche’s Taycan Turbo S, equipped with this technology, recorded zero insulation failures during 1,000 cycles of 5C charging.

High-Voltage Performance
The coating’s dual-layer design—an inner polyimide layer for dielectric strength (8kV/mm) and an outer silicone-acrylic layer for mechanical resilience—achieves a breakdown voltage 25% higher than PET. Its low modulus (30MPa) accommodates cell swelling during charging, reducing stress-induced cracks by 50%.

Sustainability and Compliance
Lankwitzer’s waterborne UV formulation eliminates VOC emissions, reducing carbon footprints by 60%. The material’s 92% recyclability aligns with EU REACH and China’s GB 38031 standards, with 80% of production waste repurposed into new coatings.

Production Milestones
Lankwitzer’s Leipzig plant, built in collaboration with Goldbeck Nordost, now produces 20 million meters of UV coating monthly, serving 60% of China’s 800V EV market. The facility’s carbon-neutral manufacturing process sets a new standard for sustainable battery materials.
