In the field of precision manufacturing, high-strength UV adhesive for glass has become the preferred material for glass bonding. It is instantly cured by ultraviolet light (3-10 seconds) to form a transparent, weather-resistant permanent bonding layer with a mechanical strength of over 20MPa, which completely changes the limitations of traditional adhesives, such as slow curing, easy yellowing, and containing solvents.
1. Industry application and performance advantages
Glass precision assembly
UV glue performs well in the bonding of automobile windshield positioning pins and medical dialysis catheters, and can withstand temperature differences of -40℃ to 150℃ and chemical corrosion. KEOL's medical-grade UV glue has passed ISO10993 certification to ensure the bonding stability of the device during sterilization.
Electronic optics
More than 90% transmittance and anti-yellowing properties make it the core packaging material for AR lenses and flexible OLED screens. Shenzhen U-Sunny's optical-grade resin HM-103 has a refractive index of >1.65 and a shrinkage rate of <3%, which is suitable for high-precision scenarios such as 5G optical fiber modules.
Environmental protection and efficiency revolution
Compared with solvent-based pressure-sensitive adhesives (containing more than 30% VOCs), UV glue achieves zero solvent volatilization and reduces curing energy consumption by 70%. UV pressure-sensitive tape has the dual characteristics of rapid bonding and permanent bonding.
2. Technological breakthrough: T-7130 high adhesion UV resin
The T-7130 special resin launched by Shenzhen U-Sunny is specially designed to solve the difficulties of bonding glass/metal heterogeneous materials:
Adhesion enhancement: Through the modification of vinyl ether monomer, the glass surface can be improved by 50%, and the peel strength reaches 8.5N/mm²;
Dual curing mechanism: UV pre-curing + thermal post-curing to ensure complete cross-linking of the shadow area;
Weather resistance upgrade: Fluorinated resin technology (such as T-6139) gives anti-UV aging performance and a service life of more than 10 years.
This material has been used in high-end cosmetic bottle packaging and spacecraft porthole bonding, replacing epoxy resin solutions.
3. Market trends and U-Sunny's leading position
The global UV adhesive market will expand at a compound annual growth rate of 7.1% (2025-2030), and Chinese companies are gradually breaking through in the research and development of environmentally friendly products. Shenzhen U-Sunny has established a full-chain system from monomer synthesis to application testing with 20 years of accumulation of light-curing technology. Products such as T-7130 have been exported to more than 20 countries, serving leading customers in the medical and new energy industries.
