Yuanjingang Armor Coating: Enhanced Protection, Flame Retardancy, and Eco-Friendliness:for EV Battery Underbody Shields

In the rapidly advancing landscape of new energy vehicles (NEVs), battery safety remains paramount. As the primary defense against thermal runaway, the performance of the battery underbody shield directly impacts the integrity of the battery pack and, consequently, the safety of the entire vehicle.

Conventional PVC-based protection solutions often prove inadequate. The inherent softness of the substrate makes it prone to deformation under impact, leaving the battery pack vulnerable to puncture and extrusion damage. Furthermore, the underbody shield is highly susceptible to corrosion from environmental factors such as road salts, acid rain, and coastal salt spray.

Recognizing these critical challenges, Yuanjingang special protective coatings, leveraging their superior performance, have partnered with a prominent EV battery manufacturer to provide comprehensive and highly effective protection for new energy vehicle battery underbody shields.

The Unparalleled Advantages of Yuanjingang Special Protective Coatings

Yuanjingang special protective coatings offer a comprehensive solution to the critical challenges facing NEV battery underbody shields, achieving a significant upgrade in protective performance.

1. Exceptional Strength and Toughness for Impact Resistance

· High Strength and High Toughness: Yuanjingang material overcomes the traditional engineering paradox where "high strength must be brittle." It masterfully combines both high strength and high toughness, creating a resilient protective layer.

· Rigorous Stone Impact Protection: Having passed stringent stone impact resistance testing, the coating effectively shields the battery pack from bottom impacts and gravel strikes, ensuring "crack-free and penetration-resistant" protection. This significantly mitigates the risk of short circuits and fire hazards post-impact, providing robust security for the battery pack.

2. Flame Retardant, Anti-Corrosion, and Waterproof – Life-Long Protection

· UL94-V0 Flame Retardancy: This critical feature effectively blocks the propagation of thermal runaway, substantially enhancing the fire safety of the battery pack.

· Excellent Anti-Corrosion and Waterproof

 Properties: It forms an impenetrable barrier against corrosive media such as acid rain, road salts (snow melting agents), and coastal salt spray, fundamentally addressing the corrosion issue of the underbody shield and safeguarding battery integrity throughout its life cycle.

3. Optimized Application Process

· Uniform Coverage and Smooth Finish: Ensures a consistent coating thickness and smooth edges, thoroughly encapsulating every contour of the battery underbody shield.

· Flexible Multi-Angle Application: The construction process allows for flexible adjustment at multiple angles, guaranteeing uniform coverage without blind spots, even on complex geometries.

4. Green and Environmentally Friendly

· 100% Solids Content, Zero VOC Emissions: Aligning with green environmental protection principles, our product emits zero volatile organic compounds (VOCs). The application process is environmentally responsible and safe for both the environment and production personnel.
