Momentive RTV6136-D1 and RTV6100 Series Silicone Dielectric Gels
Momentive RTV6136-D1 and the broader RTV6100 series are two-part, low-viscosity silicone dielectric gels designed for electronic protection, stress relief, cushioning, and environmental sealing. These materials cure into extremely soft, gel-like elastomers that combine the self-healing behavior of a liquid with the dimensional stability of a non-flowing elastomer.
The RTV6100 family includes multiple formulations with different cure speeds, working lives, low-temperature performance, and production handling characteristics. RTV6136-D1 is the high-strength, tougher gel option in the series, offering improved tear resistance compared with conventional silicone gels while still maintaining the softness, clarity, dielectric performance, and stress-relief characteristics expected from silicone gel encapsulants.
These gels are well suited for delicate electronic assemblies, displays, sensors, aerospace electronics, high-reliability modules, and other applications where the material must protect components without placing excessive mechanical stress on solder joints, wire bonds, surface-mounted devices, or fragile substrates. Their low viscosity helps the material flow around components and into complex geometries, while the cured gel provides shock and vibration dampening, moisture protection, dielectric isolation, and thermal-stress relief across a wide operating temperature range.
The RTV6100 series gives designers a useful range of standard choices, including fast-curing, extended-working-life, high-strength, general-purpose, and extended low-temperature variants. In addition to selecting from the standard RTV6100 series options, these silicone systems can be further optimized for application-specific requirements. Depending on the design and process window, formulations and processing methods may be adjusted or enhanced for adhesion, working life, cure profile, final softness or durometer, penetration value, optical clarity, flow behavior, and other critical characteristics.
Historical manufacturer reference: The following family comparisons are typical data from the Momentive RTV6100 Series TDS (2007). They are not FPD.DEV test results or specifications for modified formulations. Confirm the applicable grade, matched A/B lot and current documentation before using numerical values as process inputs.
| Material | General Positioning | Pot Life at 25°C | Cured Gel Character | Useful Temperature Range | Refractive Index | Typical Use Fit |
|---|---|---|---|---|---|---|
| RTV6126-D1 | Extremely fast cure | 5 minutes | Very soft silicone gel | -50°C to 200°C | 1.41 | Automated high-speed dispensing where very fast room-temperature cure is needed |
| RTV6136-D1 | High-strength / tougher gel | 30 minutes | Soft gel with improved tear resistance | -50°C to 200°C | 1.41 | Higher-reliability encapsulation where soft stress relief and improved cured strength are both desired |
| RTV6156 | Extended low-temperature performance | 1 hour | Firmer gel compared with most of the series | -115°C to 235°C | 1.43 | Harsh low-temperature applications, aerospace, outdoor, or wide-temperature electronics |
| RTV6166 | General-purpose silicone gel | 2 hours | Very soft silicone gel | -50°C to 200°C | 1.41 | Cost-effective general encapsulation, cushioning, and dielectric protection |
| RTV6186 | High-strength with long working life | 8+ hours | Soft gel with improved tear resistance and long process window | -50°C to 200°C | 1.41 | Manual or non-automated production lines where long working time is needed |
| RTV6196 | Very fast cure | 15 minutes | Very soft silicone gel | -50°C to 200°C | 1.41 | Fast production where automated meter-mix-dispense processing is available |
Reference conditions: matched A/B components at 1:1 by weight. Pot life is at 25°C; cure temperature is shown by column. Cure times depend on material temperature and assembly geometry. Newer grade-specific documentation may differ from this family reference.

* RTV6186 requires a minimum cure temperature of 60°C.
RTV6136-D1 is especially useful when a soft dielectric gel is needed but the application also benefits from greater cured strength and tear resistance. It is commonly considered for applications where reworkability, probe testability, component protection, and long-term reliability are important, but where a conventional elastomer would be too rigid or place too much stress on the assembly.
For production use, the RTV6100 series is typically supplied as matched two-component kits designed for 1:1 mixing by weight. Some fast-cure versions, including RTV6126-D1, RTV6136-D1, and RTV6196, have relatively short pot life and are best processed with automated meter-mix-dispense equipment for repeatable results. Surface cleanliness, material compatibility, cure inhibition testing, and controlled mixing are important for consistent performance.
We can support selection, modification, validation, and production process development for RTV6136-D1 and related RTV6100 series silicone gels, including optical, electronic, aerospace, display, and high-reliability encapsulation applications.
Select the formulation, pack size, and processing option for your quotation. Include the application, required quantity, dispensing method, available cure conditions, and any optical or environmental requirements. Review the current technical data sheet and safety data sheet for the exact formulation, and validate compatibility with your assembly and production process.
Optical bonding of LCD displays, OLED displays and MicroLED displays is a core FPD.DEV expertise. We develop silicone materials and processes around the complete display stack: cover glass, coatings, touch layers, bond-line thickness, optical performance and assembly requirements.
Material selection and formulation are evaluated for the actual display, substrates and cure process. A clear silicone alone does not establish compatibility with every display technology.
FPD.DEV develops modified silicone formulations outside the original manufacturer’s specifications. Manufacturer data describe the unmodified base material under the stated conditions; they do not establish the performance or approval of an FPD.DEV-modified formulation.
Custom packaging alone does not change the chemistry. Additive blending, mix-ratio changes and other formulation modifications require their own identification, mixing instructions and application-specific testing. Working time, cure, adhesion, optical clarity and storage stability are established for the modified system.
