Zirconia ceramics prepared by the sol-gel method are an ideal choice for functional materials due to their high purity, nano-scale particle size and controllable crystal phase. The N-1715 nano-zirconia sol launched by Shenzhen U-Sunny is a cutting-edge product developed based on this technology. It has an ultra-high refractive index, optical purity of Gardner chromaticity ≤2, and good flexibility, providing innovative solutions for the ink, adhesive and coating industries.
1. Coatings: Core material for high-refractive anti-reflective coatings
N-1715 Sol-gel zirconia resist has become the core material for optical display films with its ultra-high refractive index and excellent film-forming properties:
Anti-reflective film (AR): As a high-refractive index layer of a multi-layer anti-reflective structure, it significantly reduces interfacial light loss and improves display clarity;
Flexible display substrate (OLED/QLED): Hydrolysis resistance adapts to complex environments, and wetting and leveling properties ensure uniform coating of curved substrates;
Wear-resistant coating: Compounded with polymers (such as polyurethane) through the sol-gel process, the hardness reaches 3-4H, and the wear resistance is greatly improved.
2. Adhesive field: key technology to enhance interface bonding strength
Sol-gel zirconia resist solves the problem of traditional bonding failure through nano-level penetration and chemical bonding:
Dental ceramic bonding: The zirconia-ceramic interface treated with 0.5mol% sol-gel has a bonding strength that is more than 50% higher than that of sandblasting, reducing the risk of restoration falling off;
Resin-based composite materials: N-1715 is compatible with epoxy resin/acrylate to form an "inorganic-organic hybrid network", and the tensile strength is increased by 35%;
Flexible electronic packaging: 30% elongation at break adapts to substrate deformation and avoids interface cracking.
3. Ink field: the innovation engine of functional printing
High refractive index ink: N-1715 is soluble in ester/ketone solvents and compatible with UV resin for optical lens printing, achieving a transmittance of >95%;
Corrosion-resistant printing layer: Zirconia sol coating increases the corrosion resistance of metal substrates by 200%, suitable for electronic component protection;
Catalytic ink carrier: Nano-zirconia mesoporous structure (pore size 1.8-4.8nm) loads catalyst to improve reaction efficiency.
Sol-gel zirconia resist technology is reshaping the boundaries of functional materials. Shenzhen U-Sunny's N-1715 provides high-refractive printing solutions for inks with nano-level precision and multi-scenario adaptability, injects strong bonding force into adhesives, and provides optical and mechanical dual protection for coatings. As a global leader in UV curing, U-Sunny continues to promote industrial innovation of sol-gel technology.
