As electronic components become increasingly compact and precise, protection materials need to maintain stable performance under changing temperature conditions while providing low stress, transparency, and moisture protection. IOTA GNJ 3128H Phenyl Silicone Gel is a two-component addition-cure silicone gel that can cure at room temperature or be heat-cured for faster curing, providing flexible protection for electronic components and precision devices.
GNJ 3128H offers excellent resistance to both high and low temperatures and can be used continuously within a temperature range of -59°C to 250°C. This makes it suitable for applications exposed to significant temperature variations. After curing, the gel maintains its elasticity over a wide temperature range. Its low-stress characteristics help reduce the stress that the protective material may exert on sensitive components, while also making the cured material easier to repair when required.
For applications requiring transparent protection, GNJ 3128H provides high optical transparency and long-term resistance to yellowing, making it suitable where transparency and long-term appearance stability are important. During curing, it generates no by-products and features low volatility and no solvent, allowing deep curing and providing protection for electronic components with different structures and thicknesses.
GNJ 3128H also offers good water resistance, moisture protection, and aging resistance, helping reduce the impact of external environmental conditions on electronic components and supporting long-term protection.
Wide Temperature Range — Suitable for long-term use from -59°C to 250°C.
Low-Stress Flexible Protection — Maintains elasticity after curing and is easier to repair when required.
High Optical Transparency — Suitable for transparent protection and applications where internal components need to remain visible.
Yellowing Resistance — Helps maintain transparency and appearance over time.
Flexible Curing Options — Can be cured at room temperature or heat-cured for faster curing.
Clean Deep Curing — Produces no by-products, features low volatility, contains no solvent, and allows deep curing.
Moisture & Aging Protection — Provides good water resistance, moisture protection, and aging resistance.
GNJ 3128H is mainly suitable for moisture protection of electronic components, internal coating of transistors and integrated circuits, and elastic bonding of optical instruments, providing flexible and transparent protection for electronic and precision devices.
