In the manufacturing of optical fiber, the lifeblood of high-speed information transmission, UV coating for fiber optics is more than just a process; it serves as a crucial barrier to ensure the long-term, stable operation of optical fibers. This thin, almost cicada-wing-thin protective layer directly determines the fiber's ability to withstand microbend losses, environmental corrosion, and mechanical damage. The foundation of this barrier's performance lies in its core material: high-performance UV-curable resin.
Among numerous technology options, cationic-curing resins are becoming the preferred solution for high-end optical fiber coatings due to their unique advantages. Their curing process is free of oxygen inhibition, exhibits minimal volume shrinkage, and the cured coating exhibits low internal stress and excellent adhesion, providing more stable and long-lasting protection for optical fibers. The value of cationic-curing resins is particularly evident in high-reliability applications.
Deep Quest's U-9310 is a cutting-edge cationic-curing resin developed specifically to meet the stringent requirements of optical fiber coatings. Carefully designed and rigorously validated, it provides optical fiber manufacturers with industry-leading solutions, significantly improving product performance and production line efficiency.
U-9310: Enabling the Next Generation of Fiber Coatings
Excellent Curing Efficiency and Stability:
U-9310 exhibits extremely high reactivity under standard UV LED or mercury lamp light sources, enabling extremely fast fiber drawing speeds and significantly improving production efficiency.
Its cationic curing properties ensure deep and thorough curing, resulting in a uniform, tack-free, and flawless surface, even with high coating thicknesses or complex geometries.
Extremely low shrinkage during the curing process minimizes internal stress in the coating, protecting the delicate fiber glass surface, significantly reducing the risk of microbend loss, and ensuring long-term signal transmission stability.
Unparalleled Protection:
The cured coating of U-9310 exhibits excellent chemical resistance, effectively resisting moisture, acids, bases, solvents, and other environmental agents that penetrate the fiber surface and cause damage and signal degradation.
Excellent thermal stability ensures stable performance over a wide temperature range (-40°C to +85°C and even higher), making it suitable for a variety of harsh deployment environments.
An extremely low moisture vapor transmission rate (MVTR) is a critical barrier to protect optical fiber glass from water molecules, maintaining long-term mechanical strength and optical performance.
Excellent Mechanical and Optical Properties:
The coating exhibits an ideal balance of flexibility and elastic modulus, providing sufficient cushioning protection to effectively absorb external impact and lateral pressure, preventing fiber breakage, while also preventing excessive deformation that could lead to signal loss.
High abrasion resistance protects the fiber from scratches during subsequent processing (such as coloring, secondary coating, and cabling) and during installation and use.
Excellent transparency ensures that the coating itself does not introduce additional optical signal loss.
Optimized Processability:
U-9310 exhibits excellent rheological properties (viscosity and leveling), making it suitable for high-speed coating processes and capable of producing a smooth, defect-free coating with uniform thickness.
Excellent adhesion to common optical fiber glass (such as silica) and colorants and coating materials (such as nylon and PBT) ensures the integrity of the coating system throughout the fiber's lifecycle.
