SilGel® 612 A/B – Two-Component Silicone Gel for Professional Electronics Protection

SilGel® 612 A/B is a two-component, exceptionally soft RTV-2 silicone gel designed for professional protection of sensitive electronic circuits. With its very low viscosity and 1:1 mixing ratio, the material easily penetrates the smallest gaps, crevices, and complex module geometries, forming a clear, uniform protective layer. Once cured, it forms a flexible, self-leveling gel with excellent electrical insulation properties, safeguarding electronics against moisture, corrosion, contamination, and environmental influences.

A key feature of SilGel® 612 is its ultra-low hardness, which prevents mechanical stress on delicate components. The gel effectively dampens vibrations, compensates for mechanical stresses, and protects soldered connections as well as elements with differing thermal expansion coefficients. This makes it ideal for applications requiring vibration resistance and high thermal endurance—particularly in automotive modules, power electronics, and control systems.

SilGel® 612 cures evenly at low temperatures, eliminating the risk of overheating components during production. It maintains high transparency, facilitating later diagnostics and maintenance, while its long-term stability ensures multi-year protection even under harsh external conditions. The material is resistant to moisture, environmental stress, and electrolytic corrosion, making it well-suited for outdoor electronics and modules operating across a wide temperature range.

Applications of SilGel® 612 include:
– Potting and protection of ECU, PCU, BMS, and automotive electronics modules
– Safeguarding control circuits, sensors, and delicate SMD components
– Power electronics, converters, power supplies, and HVAC devices
– Automation systems, measurement equipment, and components exposed to constant moisture or vibration

SilGel® 612 A/B combines ease of application with exceptional flexibility and parameter stability. In practice, it significantly extends device lifetime, reduces failure rates, and provides a high level of protection in projects requiring reliability. It is one of the most dependable silicone gels for professional electronics protection—a choice that enhances both safety and durability of modern electronic systems.
