Lead-Acid Battery Hot Melt Adhesive

1.Long-Term Sealing to Eliminate Leak Risks

The corrosive acid mist generated during battery operation is the primary threat. Once cured, our adhesive forms a dense seal with extremely low permeability, effectively blocking acid mist from escaping through the micro-gaps between the metal terminal and plastic case. This fundamentally prevents terminal corrosion and self-discharge issues caused by “acid creep.”

2.Engineered for Extreme Temperatures & Vibration

The under-hood environment is exceptionally harsh—local temperatures can exceed 100°C in summer and drop to tens of degrees below zero in winter, coupled with constant engine vibration. Our adhesive undergoes rigorous thermal cycling and vibration tests, ensuring the seal remains intact, non-cracking, and non-peeling throughout the battery’s entire service life, maintaining a resilient, sealed state.

3.Superior Chemical Resistance

The formulation is specifically optimized for battery environments, demonstrating exceptional resistance to dilute sulfuric acid and acid mist. Long-term exposure will not cause the adhesive to swell, soften, or lose bonding strength, guaranteeing the durability and reliability of the seal.
