WANAN INSULATING POWDER COATINGS, THE "INVISIBLE" GUARDIANS OF FAST AND FURIOUS

As the core power source of new energy vehicles, the insulation performance of power batteries decreases, which may lead to short circuits in batteries, cause vehicle failures, increase the risk of electric shock, and pose a serious safety threat to drivers and passengers. Frequent insulation failures will undoubtedly reduce consumers' trust in new energy vehicle brands, which in turn will damage brand image and market competitiveness. Doing a good job in the insulation design of power batteries has become the key to ensuring the safety of drivers and passengers, maintaining the stable operation of vehicles, extending the service life of batteries and enhancing the brand image of automobiles.

Through strict experimental tests, it is proved that the coating volume insulation resistance of WANAN insulating powder coating reaches more than 1*1016Ω·m, the dielectric strength > 40KV/mm, and the insulation withstand voltage of the coating reaches more than 3800V (the above experimental results are based on the physical and chemical test of 0.8mm thick 3003 aluminum plate and film thickness 200±50μm, and the actual performance of the product is slightly different due to different application environments). It can provide stable and reliable insulation protection for new energy vehicle battery packs and other parts, effectively isolate the current, protect the personal safety of drivers and passengers, and ensure that new energy vehicles can operate for a long-term, stable and safe time in a complex and changeable environment.

With the significant increase in the range of new energy vehicles, the number of battery packs in series has also increased, resulting in a significant reduction in the spacing between the cells, which has exacerbated the risk of thermal runaway in the event of abnormal conditions such as short circuits and collisions. Once the battery thermal runaway leads to a fire, its high energy density often leads to the fire is difficult to control, which is one of the main culprits causing new energy vehicle safety accidents. Strengthening the fire safety design of battery packs to prevent and reduce the serious consequences caused by thermal runaway is the key link to ensure the safety of new energy vehicles.

WANAN insulating powder coatings are halogen-free (e.g. bromine, chlorine), halogen-free flame retardant, exhibit excellent environmental friendliness during production, use and handling, and meet the UL94 V-0 flame retardant standard while reducing potential harm to the ecosystem, i.e. the flame can be extinguished in a very short time (within 10 seconds) after two combustion tests on the sample. In practical application scenarios, it can effectively slow down the spread of fire, maximize the valuable escape time for drivers and passengers, and maximize the safety of life and property.

In the complex and changeable driving environment, the battery pack of new energy vehicles has to withstand multiple challenges such as high temperature, oxidation, and sediment erosion. The surface material of the battery pack must have excellent weather resistance, scratch resistance and impact resistance. It is very important to do a good job in the surface wear protection of the battery pack of new energy vehicles, which can effectively resist physical impact, moisture invasion and chemical corrosion during driving, prolong the battery life, and ensure the overall safety performance of the vehicle, thereby enhancing consumer confidence and promoting the popularization and application of new energy vehicles.

Through repeated tests on the hardness, adhesion and impact resistance of the WANAN insulating powder coating model, it has been proved that the impact strength of VIE insulating powder coating is ≥ 50 kg·cm, and the adhesion of the coating meets the level 0 adhesion (IOS standard assessment is divided into 0-5 grades, of which grade 0 is the best and grade 5 is the secondary), which can effectively avoid potential safety hazards caused by the aging of battery pack parts and external collisions of new energy vehicles. The 1000h constant damp heat test proves that the coating of WANAN insulating powder coating has excellent water resistance, damp heat resistance, and the tested coating has no cracking, falling off, blistering and discoloration, and the coating can still meet the requirements of insulation and withstand voltage after wiping, which fully proves the reliability of WANAN insulating powder coating in complex and changeable use scenarios, and minimizes the degradation of vehicle performance and shortening of life caused by external factors.

With the vigorous development of new material technology, WANAN insulating powder coatings keep up with market demand, and strive to achieve better decorative effects and better protective properties. We have always been committed to providing customers with one-stop coating solutions and continuing to create maximum value for customers. In the pursuit of speed and passion at the same time, let every trip worry-free, for the popularization and development of new energy vehicles to contribute more WANAN strength.
