Low Viscosity Electronic Silicone Gel 1:1 IP68 Waterproof for EV Battery Pressure Sensor Potting Flame Retardant

Low Viscosity Electronic Silicone Gel for EV Battery and Pressure Sensor Potting

This electronic-grade silicone gel is a highly elastic liquid silicone rubber that cures via cross-linking reaction into a soft, jelly-like solid, primarily used to protect sensitive electronic components in new energy vehicles and industrial sensors. Its low viscosity and excellent flowability enable bubble-free potting of dense and complex assemblies.

Key Features

• Low Viscosity & Self-Leveling: 800-2000 cps ensures excellent flowability and bubble-free filling of tight spaces, compatible with automated dispensing equipment.
• EV Battery Protection: Ideal for battery management systems (BMS), battery cell modules and high-voltage connectors in electric vehicles.
• Pressure Sensor Encapsulation: Ultra-soft Shore A 0-10 cure applies zero stress on sensitive pressure sensors, diaphragms and wire bonds.
• IP68 Waterproof: Seamless protective seal against water immersion, moisture and condensation for demanding automotive environments.
• Flame Retardant: Flame retardant formulation with optional UL94 V0 rating enhances fire safety of EV power systems.
• Wide Temperature Range: Stable performance from -50°C to +200°C, withstanding high and low temperature cycling.
• UV & Yellowing Resistance: Anti-yellowing, UV-resistant formula maintains optical clarity for long service life.
• Adjustable Formulation: Viscosity and curing time can be customized; fillers such as thermally conductive powder and pigments can be added.
