Due to its excellent weather resistance, polyaspartic polyurea is widely used for power battery encapsulation and potting. It also features flame retardancy, which helps delay the aging and flammability of battery potting materials, reducing the risk of thermal runaway and ensuring driver safety.

Due to the larger molecular spatial steric hindrance and UV resistance properties of Polyaspartic Polyurea, crystal products made from Polyaspartic Polyurea, compared to traditional epoxy resins, have the advantages of being non-yellowing and having high transparency. Additionally, they are easier to manufacture and less prone to breaking compared to crystals.
