Anhui Aiyueta Silicon Oil Co., Ltd. recently announced that its phenyl silicon gel IOTA 3128 has achieved an important breakthrough in the field of optical instrument bonding. This material has the characteristics of high transparency and deep curing without bubbles, which solves the problems of light transmittance attenuation and uneven curing of traditional adhesives in precision optical component packaging.

    The viscosity of IOTA 3128 after mixing is controlled at 600 ± 200cp, with an operating time of ≤ 60 minutes. It can be sealed with a thickness of over 10mm through vacuum defoaming process, and no small molecule by-products are generated during the curing process, ensuring that the transmittance loss of optical lenses, lasers and other devices is less than 5%. At the same time, its resistance to yellowing is excellent. After 2000 hours of double 85 testing (85 ℃/85% RH), the color difference Δ E value is only 1.2, which meets the long-term use needs of high-end medical endoscopes, AR/VR equipment, and other devices.

    After a certain international brand projector manufacturer replaced imported glue with IOTA 3128, the light efficiency loss was reduced by 40% and the production cost was reduced by 25%. ”The market manager of Anhui Aiyota revealed. This material also has self-healing properties. When microcracks are generated in components due to vibration, over 90% of the adhesive strength can be restored through local heating, significantly reducing maintenance costs.

    It is reported that IOTA 3128 has passed international certifications such as RoHS and REACH, and supports adjusting curing speed according to customer processes. The enterprise recommends that users strictly follow the "cleaning mixing defoaming coating" operation process to avoid contamination of colloids with compounds such as N, P, S, etc., in order to ensure the hardening effect. With the growing demand for high-precision and long-life materials in the optical market, this silicon gel "made in China" is accelerating to replace imported products, helping the industrial chain to be self controllable.
