In precision manufacturing fields such as electronic components, integrated circuits and optical instruments, moisture‑proof protection, internal encapsulation and elastic bonding are critical factors affecting service life and stability of products. Conventional sealing materials are vulnerable to temperature fluctuations, poor light transmittance and excessive stress that may damage precision parts. Phenyl silicone gel, with outstanding comprehensive performance, serves as an ideal material for protection and bonding of high‑end precision devices.



This product is a two‑component addition‑cure silicone gel with flexible application. It cures naturally at room temperature without complicated equipment, or can be rapidly cured under heating to match various production processes. No by‑products are generated during curing. It is solvent‑free with low volatile content and eco‑friendly. Its deep‑curing capability meets requirements of thick‑layer encapsulation and deep filling, avoiding hidden risks caused by incomplete internal curing.

Excellent temperature resistance is one of its core advantages. It can be stably used long‑term within the wide temperature range of -59℃ to 200℃, free from hardening, cracking or failure under extreme low or high temperatures. After curing, it features low stress and maintains high elasticity over a broad temperature range, preventing extrusion damage to precision components such as transistors and integrated circuits due to thermal expansion and contraction. It is easy to peel off and repair during maintenance, greatly reducing equipment maintenance costs.

For optical instrument applications, this silicone gel boasts high light transmittance and long‑term yellowing resistance. It hardly turns yellow or becomes turbid after long‑term use, without impairing imaging accuracy and light transmission of optical equipment, making it an ideal elastic adhesive for optical instruments.

In addition, it delivers superior waterproof, moisture‑proof and anti‑aging properties. Its dense gel structure blocks moisture intrusion to prevent oxidation and short circuits of chips and circuit boards. With slow performance degradation over time, it effectively extends the service life of electronic components and optical instruments.

With advantages including low stress, high light transmittance, wide temperature resistance, deep curing, waterproofing, moisture resistance and easy repair, phenyl silicone gel is widely applied in moisture‑proof protection of electronic components, internal coating of transistors and integrated circuits, and elastic bonding of optical instruments. It provides stable and reliable material solutions for precision electronics and optical manufacturing industries, helping improve product quality and durability.
