As electronic devices trend toward higher power and greater integration, ensuring the safe operation of components in complex environments has become a challenge that design engineers must address. A potting compound with excellent flame retardancy and waterproof performance—represented by black/white series products such as LSR 3304G and 3411G—is emerging as an ideal solution to elevate device safety standards.

This product series boasts UL94-V0 level high flame retardancy, enabling rapid self-extinguishing in open flame conditions, effectively suppressing flame spread, and significantly enhancing the fire safety of electronic devices. Additionally, it achieves a waterproof rating of up to IPX6 to IPX8, making it suitable for harsh environments such as exposure to strong water jets or prolonged immersion. It is ideal for applications like outdoor power supplies, charging stations, and industrial controllers.

In terms of electrical performance, the compound offers excellent insulation, with a volume resistivity of ≥10¹⁴ Ω·cm and a breakdown voltage of ≥20 kV/mm, effectively shielding circuits from moisture and contaminants. Its thermal conductivity of ≥0.8 W/m·K provides a certain level of heat dissipation capability, helping components maintain stability under high-load operation.

With a hardness of 30±5 Shore A, this product series exhibits good flexibility and impact resistance, effectively mitigating damage to components caused by vibration and mechanical stress. Certain models (e.g., LSR 3411G and 3311G) also feature direct adhesion capabilities to electronic components, simplifying the assembly process and enhancing structural integrity.

In terms of application, all models feature a 10:1 mixing ratio, with a working time of 30–40 minutes and a curing time of 4–6 hours, making them suitable for small to medium-batch continuous operations. For improved encapsulation quality, it is recommended to use vacuum defoaming or automated dispensing equipment during application.

Whether for new energy vehicle electronic control systems, energy storage equipment, industrial frequency converters, or communication base stations, this flame-retardant and waterproof potting compound, available in multiple colors, provides comprehensive safety protection for electronic devices, ensuring stable operation in harsh environments.
