Premium Silicone Gel for Professional Applications
ALPA-GEL 97166 is a high-quality, transparent silicone gel based on platinum catalysis (addition-cure), specially developed for encapsulating and protecting sensitive electronic components. This two-component gel combines excellent damping properties with reliable electrical insulation and thermal stability.
Key Benefits
- Excellent damping properties – effectively absorbs vibrations and shocks, protecting sensitive components
- Transparent finish – visual inspection remains possible after encapsulation, ideal for quality control
- Low viscosity – penetrates easily into complex geometries and around small components
- Platinum-cure system – no by-products during curing, safe for sensitive electronics
- Electrical insulation – protects against moisture, dust, chemicals and electrical breakdown
- Thermal stability – retains mechanical and electrical properties over a wide temperature range
Typical Applications
- Encapsulation of printed circuit boards (PCBs) and electronic modules
- Potting of battery packs for e-bikes, drones, automotive and energy storage
- Protection of sensors, connectors and switching components
- Damping of vibration-sensitive components in automotive and aerospace
- LED modules, lighting systems and display electronics
- Medical equipment and wearable electronics
Technical Characteristics
ALPA-GEL 97166 is an addition-cure (platinum catalysis) system that allows curing at room temperature, with optional acceleration by heat. The low viscosity ensures optimum penetration and degassing during pouring. The transparent finish allows visual inspection after processing, while the soft gel consistency minimises mechanical stress.
Manufacturer: CHT Germany – a globally recognised specialist in high-quality silicone systems for industrial and professional applications.

Safety Information
According to the CHT safety data sheet, component B of ALPA-GEL 97166 is classified as harmful to aquatic life with long lasting effects (H412). No signal word and no hazard pictogram apply to this classification. Component B contains a small amount of octamethylcyclotetrasiloxane (D4), a substance on the REACH Candidate List, and can generate flammable hydrogen gas under certain conditions. Work in a well-ventilated room and wear nitrile gloves and eye protection. Avoid release to the environment: do not let residues or rinse water enter drains or soil, and dispose of contents and packaging via a licensed waste disposal company.
