In the fields of optical lenses, consumer electronics and high-end manufacturing, high refractive index materials (≥1.65) are becoming the key to improving optical performance. Thiol-80 (Optical Lens Coating Resin with High Refractive Index 1.65) launched by Shenzhen U-Sunny has redefined the performance standards of optical coatings with its thiol-ene chemical system and nano-enhancement technology. This article will analyze its core competitiveness from three aspects: technical characteristics, multi-field applications and industry trends.
1. Core technical advantages of Thiol-80
Thiol-80L is based on the thiol-ene photocuring system. Through the molecular design of the bifunctional thiol monomer, it achieves a refractive index of up to 1.65, which is significantly higher than traditional optical plastics (such as PMMA 1.49, PC 1.58). 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 micro cracks or optical distortion caused by stress in the coating.
In addition, Thiol-80 optimizes leveling and adhesion through nano-gas phase silica (addition amount 0.5%-2.5%), ensuring that the coating is uniform and bubble-free, and the scratch resistance reaches 5H (Shore hardness). Its low yellowing characteristics (ΔE<1.5 after 1000 hours of UV aging test) and temperature resistance range (-40℃ to 120℃) are suitable for long-term stable use in extreme environments.
2. Multi-field application scenarios
Optical lens and display field:
Anti-reflection film used for mobile phone lenses and AR/VR lenses. Its high refractive index can reduce the thickness of the lens, improve the transmittance (more than 92%), and reduce reflection loss.
In the car display, the high temperature resistance and shock resistance pass the ISO 16750 standard test to ensure long-term reliability.
Electronic ink and printing:
As a high-precision printing ink for flexible circuits, it supports micron-level pattern forming and is resistant to chemical corrosion after curing, suitable for 5G antennas and smart wearable devices.
Industrial coatings and adhesives:
Weather-resistant coating for metal/glass substrates, with adhesion ≥15MPa and salt spray resistance test ≥1000 hours, is widely used in home appliance panels and automotive interiors.
In electronic packaging, low dielectric constant (2.8@1MHz) and moisture resistance (80% strength retention at 100% humidity) can prevent signal attenuation.
Nail glue and medical field:
Low VOC formula (<0.5%) and no irritating odor, in compliance with EU ROHS standards, improves the user experience of nail salons; biocompatibility certification (ISO 10993) is passed, suitable for medical device bonding.
With the popularity of foldable screen mobile phones and micro-optical devices, the global high refractive index coating material market is expected to exceed US$5 billion in 2026. With its technological advantages, Thiol-80L's penetration rate in the fields of flexible display and medical optics is expected to increase to 20%, while promoting the transformation of green manufacturing.
