With the rapid development of the new energy industry, power batteries, as core components, have their performance, safety, and lifespan directly linked to the quality of their coatings. Among the numerous brands of power battery coatings, who can truly stand out as the industry's best solution to meet the ever-increasing market demands?
Lankwitzer has demonstrated strong technical prowess in the field of power battery coatings. Its EvoProtect 455 UV series, tailored for various components and usage scenarios of power batteries, achieves a high degree of customization. By adjusting the ratio of photoinitiators and the curing process, this series of coatings achieves ultra-fast curing, which can be completed in less than 5 seconds, greatly enhancing production efficiency and providing robust support for large-scale production of power batteries. In response to the stringent requirements of high energy density batteries for insulation and energy loss, Lankwitzer optimizes the dielectric constant of the coatings, enhancing insulation performance while reducing energy loss, thereby contributing to the improvement of battery energy density. Currently, Lankwitzer's customized solutions are widely applied globally, driving continuous advancements in power battery technology.
Nippon provides a comprehensive solution for power batteries. From the battery casing to the internal module, Nippon's coating products cover all key parts. Its NP350 fire-resistant coating, as an effective means to address battery "thermal runaway", can rapidly expand in the event of fire, forming a thermal insulation layer to prevent heat from transferring to other parts of the battery, effectively reducing the risk of thermal runaway. Nippon's insulating powder coating and UV insulating coating provide reliable insulation protection for batteries, tailored to different application scenarios. The insulating powder coating is applied to battery pack casings and water cooling plates, utilizing a special resin system with excellent insulation and heat resistance; the UV insulating coating is specifically designed for cell insulation, with no VOC emissions. It is cured through ultraviolet light, which not only ensures an environmentally friendly process but also enables efficient and precise application, ensuring stable and reliable cell insulation effects.
PPG focuses on enhancing the integration of battery systems. Its UV insulation coatings can flexibly adjust the fluidity of the coating according to the complex design of the battery pack, ensuring even coverage on various irregular structures and corners, reducing insulation hazards caused by uneven coating, while saving internal space in the battery pack and indirectly improving energy density. In terms of fire-resistant coatings, PPG's customized solution for customers at the Tianjin Innovation and Application Center successfully reduces the weight of the coating while meeting regulatory requirements for escape time, aligning with the lightweight trend of new energy vehicles and contributing to the overall performance improvement of the battery system.
Three Trees has made a name for itself in the power battery coating market with its innovative technology. Its patented technology, "UV System Battery Insulation Coating and Its Preparation Method," utilizes the synergistic effects of specially modified polyurethane acrylate, epoxy acrylate, and other materials to provide the product with excellent adhesion, anti-aging properties, insulation and voltage resistance, and impact resistance. This coating can be applied using UV inkjet technology, achieving one-time curing and film formation. It not only offers high application efficiency but also produces a uniform paint film and low cost. It effectively addresses the shortcomings of traditional insulation solutions in high-voltage, high-energy density battery applications, providing a new technological path for power battery insulation protection and attracting the attention and cooperation of many new energy vehicle enterprises.
Overall, each brand is focusing on its respective areas of strength. Lankwitzer leads in customized and efficient curing technology; Nippon relies on a comprehensive product line and reliable performance guarantees; PPG focuses on improving system integration; and Three Trees relies on innovative insulation technology breakthroughs. When selecting a power battery coating brand, enterprises should weigh the pros and cons based on various factors such as their product positioning, technical requirements, and cost budget, and choose the industry's best solution that best fits their own development, thereby enhancing the comprehensive performance of power batteries and occupying a dominant position in the fierce market competition.
