ОБЗОР
Silicone encapsulants are RTV silicone materials used to protect electronic components, connection points, LEDs, sensors, modules and electrical assemblies. After curing, they form a flexible protective layer that can help provide electrical insulation, moisture resistance, dust protection, stress relief and environmental sealing.
Для разных областей применения требуются разные свойства материалов. Для одних лучше подходит мягкий, повторно вводимый силиконовый гель для амортизации и облегчения обслуживания, а для других требуются силиконовые герметики для более стабильной инкапсуляции и более широкой защиты компонентов.
| Project Requirement | Силиконовый гель | Силиконовая заливочная смесь |
|---|---|---|
| Very soft cured material | Recommended | Depending on grade |
| Minimum stress on sensitive components | Excellent starting direction | Good with softer grades |
| Easier future re-entry | Recommended | Более ограниченный |
| PCB and module encapsulation | Application-dependent | Recommended starting direction |
| Greater cured mechanical support | Ограниченный | Better choice |
| Cable joints and connectors | Common direction | Application-dependent |
| Moisture/environmental protection | Да | Да |
| Automatic dispensing | Grade-dependent | Grade-dependent |
For LED modules and light components that require flexible protection, sealing, and optical or environmental stability.
For circuit boards that need insulation, moisture protection, vibration resistance, and more stable environmental sealing.
Для систем кабельных аксессуаров, требующих изоляции, герметизации и надежной защиты от воздействия окружающей среды.
Для защиты разъемов от проникновения влаги, загрязнений и механических воздействий.
