Premium Liquid Silicone Foam for Professional Potting & Encapsulation

SilSo Lite 21030 is a two-component, platinum-cure, self-blowing silicone foam developed for machine dispensing applications. This lightweight material combines excellent flow properties with thermal protection and electrical insulation, specifically designed for potting EV battery modules, electronics, and complex components where weight reduction and environmental protection are crucial.

Key Benefits

• Lightweight foam structure: Medium density foam with 2-3x volume expansion, ideal for weight-critical applications
• Excellent flow properties: Viscosity profile optimized for flow around complex components and PCB stacking
• V0 Fire Protection: Low-smoke formulation with the highest fire resistance rating for safe electronic applications
• Platinum-cure technology: Hydrolytically stable and reversion-resistant for long-term reliability
• Low pressure building: Controlled level rise prevents damage to sensitive components during curing
• Electrical insulation: Provides physical shock resistance and environmental protection for critical electronics

Typical Applications

• Lightweight potting and encapsulation of EV battery modules and power electronics
• PCB staking and protection in automotive and aerospace electronics
• Thermal insulation and environmental sealing of sensitive components
• Potting of complex assemblies where flow around components is essential
• Electrical insulation in high-voltage applications (inverters, converters)
• Shock and vibration protection in industrial and transport electronics

Technical Features

SilSo Lite 21030 is supplied as a two-component system designed for volume dispensing via a static mixer. Part A contains the platinum catalyst, Part B the hydride component. After mixing, simultaneous blowing and gelation reactions create a controlled foam structure with hydrogen gas generation. Ideal dispensing temperature: 20-30°C. The material expands 2-3 times its nominal volume. Gel time is approximately 120 seconds at 23°C, depending on dispensing conditions. For optimal performance, use components A and B from the same lot number. Machine dispensing is recommended due to the fast gel time.
