In the field of high-end industrial manufacturing and consumer electronics, printing and coating of metal and glass substrates have put forward strict requirements on the adhesion, weather resistance and environmental protection of materials. Thiol-80 (UV Ink with High Adhesion for Metal/Glass Substrates) launched by Shenzhen U-Sunny has become a benchmark product for UV curing materials for metal/glass substrates with its thiol-ene chemical system and nano-enhancement technology. This article will analyze its core competitiveness from three aspects: technical characteristics, application scenarios and industry trends.
1. Core technical advantages of Thiol-80
Thiol-80 is based on thiol-ene photocuring technology. It significantly improves the adhesion to metal and glass (adhesion strength ≥ 15MPa) through free radical chain reaction, and uses nano-gas phase silica to optimize thixotropy and leveling to ensure uniform and bubble-free coating. Its curing speed only takes 5-8 seconds (365nm UV LED light source), and the hardness of the cured coating reaches 5H (Shore hardness), and the wear resistance is improved by more than 30%, which is suitable for high-precision printing and complex curved surface coating.
In addition, Thiol-80 solves the problem of traditional UV ink releasing irritating odor during the curing process through a low VOC formula (VOC content <0.5%), which complies with the EU ROHS and ISO 12219-3 environmental protection standards, and is especially suitable for closed environment applications such as automotive interiors and medical equipment.
2. Multi-field application scenarios
Consumer electronics: Printing inks used for mobile phone glass cover plates and smart watch screens. Its high adhesion can withstand bending and drop tests, and it also supports micron-level circuit pattern printing.
Automotive industry: As the core material for headlight coating and interior coating, it has a temperature resistance range of -40℃ to 120℃ and has passed the salt spray test for ≥1000 hours, effectively resisting acid rain and ultraviolet aging.
Home appliances and building materials: Achieve mirror effects on glass panels, metal handles and other parts, with better anti-fingerprint and scratch resistance than traditional coatings, improving product durability and aesthetics.
Medical devices: Passed biocompatibility certification, suitable for anti-counterfeiting printing of surgical instrument labels and glass medicine bottles, ensuring long-term use without chemical migration risks.
With the popularization of 5G communications and new energy vehicles, the demand for high-performance coatings on metal/glass substrates has surged. It is predicted that the global UV curing material market will exceed US$8 billion in 2026, of which high adhesion inks will account for more than 25%. With its technological advantages, Thiol-80 will continue to lead the innovation wave of electronic inks, industrial coatings and environmentally friendly adhesives.
Shenzhen U-Sunny's Thiol-80 redefines the UV curing standard for metal/glass substrates with high adhesion, environmental protection and high efficiency as the core.
