IOTA 3128 phenyl silicone gel is a two-component addition-cure silicone material engineered for high-end protection of electronic components and optical devices. It supports room-temperature curing or heat-accelerated curing, with no by-products, solvents, or low volatility during vulcanization. The fully cured elastomer is highly transparent, maintaining excellent elasticity and insulation across -65℃~200℃, providing comprehensive protection against moisture, water, and aging.

Key Advantages

1. Superior Weatherability & Stability：Phenyl groups enhance temperature resistance—flexible at -65℃ and＜5% light transmittance loss after 200℃ aging. Long-term yellowing index＜1 ensures optical clarity, ideal for LED packaging and sensor lenses requiring high light transmission.
2. Low Stress & Repairability：Low hardness (Shore 00 20-30) buffers mechanical/thermal stress, protecting fragile transistors and ICs. Easily peelable for device maintenance, enabling secondary encapsulation and reducing repair costs.
3. Efficient & Eco-Friendly Processing：1:1 mix ratio (customizable) allows room-temperature curing (24h) or rapid 80℃ curing (2h), suitable for automated lines. VOC＜0.1% and RoHS compliance meet strict environmental standards for medical and aerospace applications.

Technical Highlights

• Insulation Performance：Volume resistivity＞10¹⁴Ω·cm and breakdown voltage＞25kV/mm ensure stable operation in humid environments；
• Deep Vulcanization：Penetrates over 50mm thickness for bubble-free curing；
• Substrate Compatibility：Non-corrosive to metals, ceramics, glass, and plastics (PC/ABS), with moderate adhesion for easy disassembly.

Wide Applications

• Electronics：IC insulation coating, PCB moisture protection, sensor encapsulation；
• Optics：Lens bonding, prism fixation, maintaining light transmittance and imaging quality；
• Extreme Environments：Deep-sea equipment waterproofing, polar instrument low-temperature protection, high-temperature sensor insulation.

IOTA 3128 combines "low-stress protection + high transparency" to excel in precision manufacturing, enhancing product reliability and lifespan—particularly valuable in new energy, advanced equipment, and optoelectronics industries.
