As electronic integrated circuits and precision optical instruments develop toward miniaturization and high precision, the material standards for component moisture-proof protection, buffer protection and optical bonding keep improving. Traditional packaging adhesives have obvious defects such as easy yellowing, high stress, narrow temperature resistance range and by-products during curing, which fail to meet the long-term stability requirements of high-end manufacturing. Two-component addition-cured phenyl silicone gel has gradually become the mainstream packaging and bonding material thanks to its comprehensive performance advantages.



This product adopts two-component addition silicone system with flexible operation. It cures naturally at room temperature, and heating can accelerate curing for mass automated production and lab sample testing. No small molecule by-products are generated during curing. It is solvent-free with ultra-low volatile content and supports deep-layer full curing, leaving no bubbles or corrosion risks inside devices, making it safe for internal coating of transistors and IC chips.

Its outstanding temperature resistance allows long-term service from -59℃ to 200℃ without cracking, hardening or elasticity loss under alternating hot and cold conditions. The cured gel features low stress and soft elasticity, avoiding extrusion damage to chips and optical lenses during temperature cycles. It is easy to peel and repair during maintenance, cutting rework costs and extending service life.

For optical fields, it delivers excellent light transmittance. The phenyl modified structure effectively resists yellowing caused by long-term light and heat exposure, maintaining stable transmittance for optical lens elastic bonding. Its dense molecular structure provides reliable waterproof and moisture-proof performance together with great anti-aging capacity, suitable for outdoor, vehicle-mounted and industrial control equipment.

In summary, phenyl silicone gel meets both electronic protection and optical bonding demands for IC internal coating, electronic component sealing and precision optical instrument bonding. With eco-friendly solvent-free formula, wide temperature tolerance, low stress, easy repair and long-term non-yellowing high transparency, it satisfies strict packaging standards of high-end electronics and optoelectronics, and continuously promotes quality upgrading of optoelectronic manufacturing.
