Product Introduction
Momentive SILTRUST™ RTV6186 is a two-part, low-viscosity silicone dielectric gel formulated to protect sensitive electronic assemblies. It cures into an ultra-soft, self-healing gel that provides excellent stress relief, moisture resistance, and dielectric insulation. With its optical clarity, long pot life, and primerless adhesion to many substrates, RTV6186 is well-suited for potting delicate components, hybrid modules, and surface-mount devices requiring reliable environmental and mechanical protection.
Momentive SILTRUST™ RTV6186 Features
- Extremely soft, low-modulus gel for superior cushioning
- Outstanding stress-relief properties for sensitive electronics
- Self-healing and probe-testable gel surface for rework-friendly assemblies
- Excellent dielectric performance, including 500 V/mil dielectric strength
- Excellent moisture and environmental resistance
- Primerless adhesion to many substrates
- Low viscosity (750 cps) ensures complete wetting and coverage
- Room-temperature or heat-accelerated curing
- Low shrinkage and no exothermic heat during cure
- Optical clarity for component visibility and inspection
- Operational temperature range from -50°C to 204°C
Momentive SILTRUST™ RTV6186 Applications
- Encapsulation and protection of delicate electronic circuits
- Hybrid modules and surface-mount assemblies
- High-vibration or mechanically stressful environments
- Dielectric protection in moisture-prone operating conditions
- Applications requiring re-formable, self-healing gel systems
- Deep-section potting applications where low-exotherm cure is essential
