In the field of electronic manufacturing, high-transparency UV adhesive has become the preferred material for key processes such as display bonding and chip packaging due to its fast curing, excellent optical properties and environmental protection characteristics. The T-7131 low-shrinkage UV resin launched by Shenzhen U-Sunny is promoting the industry's technological upgrade with its excellent performance.
1. Core advantages and application scenarios of electronic UV adhesive
High transparency and reliability
Optical transparency (light transmittance>99%) ensures that the display screen (LCD/OLED) has no visual defects, while providing moisture-proof and high temperature resistance (-40℃~120℃ cycle) protection to extend the life of the device.
T-7131 resin reduces curing stress and avoids micro cracks through low shrinkage design (<3%), which is suitable for bonding brittle glass and metal.
Efficient curing and process adaptability
Ultraviolet light triggers second-level curing to improve production line efficiency; supports multiple processes such as dispensing and spraying, and accurately covers micron-level components (such as camera modules and sensors).
Combined with Shenzhen U-Sunny's Uyracure series of photoinitiators, T-7131 can achieve wavelength compatibility curing and adapt to different light source equipment.
2. Collaborative innovation of ink/adhesive/pressure-sensitive adhesive
UV ink field: T-7131, as a screen printing ink resin, provides excellent pigment wettability and can achieve special effects such as ice flowers and three-dimensional gratings when used in glass decoration ink.
Innovation of pressure-sensitive adhesive: Combined with cationic curing technology, high-temperature resistant electronic label tape is developed to meet the weather resistance requirements of automotive electronics.
3. Breakthrough opportunities for domestic high-end materials
The current electronic adhesive market is dominated by international giants such as 3M and Henkel (accounting for more than 40%)
, but the trend of domestic substitution is significant:
T-7131's performance benchmark: comparable to international competitors in terms of curing speed (50 times faster than traditional epoxy adhesive) and adhesion (100 grid test 5B), and the cost is reduced by 30%.
Shenzhen U-Sunny's hard power: 20 years of experience in the research and development of light-curing materials, and ISO-certified factories to ensure mass production stability.
4. Future Trends: Green Manufacturing and Intelligent Upgrade
As the demand for miniaturized electronics grows, UV glue will evolve towards nano-filled thermal conductivity (heat dissipation needs) and bio-based raw materials (reducing carbon footprint). T-7131 has deployed a low viscosity (<500cps) formula, which is suitable for automated dispensing robots.
Conclusion: Shenzhen U-Sunny's T-7131 resin redefines the performance benchmark of electronic UV glue with its triple advantages of high transparency, low shrinkage and fast curing. If you need technical parameters or sample support, please contact +86-13686844208.
