In the fields of laser technology, optical display and precision electronics, high-performance UV-curable materials have put forward higher requirements for the bonding and protection of optical films. Thiol-80 (UV-Curable Optical Film Adhesive for Laser Applications) launched by Shenzhen U-Sunny has become a benchmark product in the fields of laser devices, flexible displays and optical communications with its thiol-ene chemical system and nano-enhancement technology. This article will analyze its core competitiveness from three aspects: technical characteristics, multi-scenario applications and industry trends.
1. Core technical advantages of Thiol-80
Thiol-80 is based on a thiol-ene photocuring system. Through the design of a bifunctional thiol monomer, it achieves a refractive index of 1.80, significantly reduces the scattering loss of laser at the interface of the adhesive layer, and improves the light transmittance of optical devices (≥92%) and laser transmission efficiency. Its curing speed only takes 5-8 seconds (365nm UV LED light source), energy consumption is 40% lower than that of traditional mercury lamps, and the curing shrinkage rate is <1%, avoiding microcracks or optical distortion caused by internal stress in the laser module.
In addition, Thiol-80L optimizes the uniformity and adhesion of the coating (≥15MPa) through nano-gas-phase silica (addition amount 0.5%-2.5%), and the temperature range is -40℃~120℃. It has passed the UV aging test (ΔE<1.5) to ensure the stability of laser equipment under long-term high-energy irradiation.
2. Multi-field application scenarios
Laser device packaging and bonding
It is used for bonding optical films of fiber lasers and semiconductor laser modules. Its high light transmittance and laser irradiation resistance (can withstand 1064nm wavelength and 10W/cm² power density) ensure the stability of signal transmission.
In the assembly of LiDAR lenses, the low shrinkage and flexibility design can absorb mechanical vibration and extend the life of the equipment.
Flexible display and optical film manufacturing
As a protective film adhesive for OLED flexible screens, Thiol-80L supports roll-to-roll coating process (adapted to heated scraper coating machine, temperature 80~120℃), achieves micron-level uniform coating (thickness error ±3μm), and improves the scratch resistance of the screen (Shore hardness 85D).
In optical functional films such as anti-reflection films and brightening films, the high refractive index characteristics can reduce interface reflection loss and increase display brightness by more than 15%.
Optical communication and electronic packaging
Used for lens bonding of 5G optical modules, its low dielectric constant (2.8@1MHz) and moisture resistance (80% strength retention at 100% humidity) prevent high-frequency signal attenuation.
In flexible circuit board packaging, the fast curing characteristics support high-precision laser etching processes to avoid damage to heat-sensitive components..
With the popularization of laser technology in the fields of medicine, communications and autonomous driving, the global UV-curable optical adhesive market is expected to exceed US$5 billion in 2026. With its technological barriers, Thiol-80's penetration rate in the fields of laser devices and flexible displays is expected to increase to 25%, and promote the transformation of green manufacturing.
