The "Battery Bodyguard"
for New Energy Vehicles:
How Robust is Lankwitzer's
3-Second Curing Coating?
The power battery of a new energy vehicle is like its "heart", and its safety protection directly determines the vehicle's reliability. The traditional PET blue film insulation solution has long plagued the industry due to issues such as easy edge warping and weak protection. However, the UV insulating coating developed by Lankwitzer (Lanwei Coatings), leveraging the "3-second ultra-fast curing" black technology, acts as a "lightning bodyguard" for batteries. It achieves breakthroughs in production efficiency, safety protection, and industrial adaptation, injecting strong impetus into the development of new energy vehicle batteries.
I. 3-Second Curing + Automation: Breaking the Bottleneck of Mass Production Efficiency
Traditional battery insulation relies on manual lamination of PET blue film, which takes more than 30 seconds per battery cell and easily leads to rising defect rates due to operational errors. Lankwitzer's UV insulating coating completely reshapes the efficiency landscape through the combination of "UV curing + automated spraying":
Ultra-fast curing: Under UV irradiation, the coating can complete the transition from liquid to solid state within 3 seconds. Its curing speed is 360 times that of traditional drying processes—equivalent to "completing the protection of thousands of battery cells in the time it takes to make a cup of coffee".
Full-process automation: Equipped with a robotic precision spraying system, it requires no manual intervention and ensures full coverage of weak areas such as weld seams.
II. Superior Protection: Double Insurance for Battery Safety
Lankwitzer's UV insulating coating is not only fast but also builds a battery safety barrier with its robust performance of "strong adhesion and high insulation":
1. Far superior adhesion to traditional solutions: The adhesion strength between the coating and the battery cell casing is three times that of PET blue film. After 1000 vibration tests (simulating vehicle bumps) and -40℃ to 85℃ high-low temperature cycle tests, there is no peeling or cracking. This completely solves the short-circuit risk caused by "edge warping and dust ingress" of blue film.
2. Maximized insulation performance: It has a dielectric strength of up to 150kV/mm and an insulation withstand voltage of over 6kVdc. Even if the battery cell suffers minor damage, the coating can effectively block current leakage and reduce the risk of thermal runaway.
3. Eco-friendly with no burden: It features zero VOC emissions, complies with national environmental standards, and helps automakers build "green battery factories".
III. Global Implementation: The "Safety Choice" for 400,000 New Energy Vehicles
With the dual advantages of high efficiency and safety, Lankwitzer's UV insulating coating has become a core supplier for global new energy automakers:
Application scale: It has accumulated to provide protection for more than 800 million power battery units, adapting to over 400,000 new energy vehicles of enterprises such as BMW, CATL, and Volvo, covering major global new energy markets.
Scenario adaptation: Through flexible spraying design, it is compatible with various battery cell types (cylindrical, prismatic, blade-type, etc.) as well as key components such as liquid cooling plates and battery casings, meeting the customized needs of different automakers.

From "slow work yields fine products" to "lightning-fast protection", Lankwitzer's UV insulating coating with 3-second curing not only solves the mass production efficiency problem of new energy vehicle batteries but also fortifies the bottom line of safety protection. This thin "invisible bodyguard suit" is becoming a key link in driving the high-quality development of the global new energy industry, ensuring the "heart" of every new energy vehicle beats steadily.
