Advanced UV Optical Adhesives for Displays, Optics and Privacy Solutions

High-Refractive-Index UV Optical & Transfer Adhesives

These UV optical adhesives are designed for applications that require a high refractive index, such as glass and PET transfer processes. After curing, the film reaches an index of about 1.61, delivering excellent clarity, strong adhesion, high light transmission and ultra-low moisture permeability. They are widely used in optics, micro-electronics, 3D displays and privacy films. In privacy structures, precision molds, transparent UV layers and black UV grating layers work together to form reliable, high-performance privacy effects.

OCA Adhesives for Touch Screens

OCA is the largest single application of UV optical adhesive today. In touch panels it provides secure bonding, improves light transmission and enhances impact resistance, while meeting strict requirements for color stability, weather resistance, electrical reliability and optical performance. It bonds to glass, ITO, PET, PMMA and PC, and when sapphire is used, higher-index UV formulations help maintain brightness and clarity.

UV Adhesives for Optical Component Fixation

In precision optical systems such as microscopes, UV adhesives are used to fix lenses and components accurately in place, ensuring stable alignment over time. These materials feature high purity, very low shrinkage and excellent transparency to avoid stress on glass lenses. They are widely applied in security optics, automotive cameras, digital imaging, lasers and optical instruments, providing strong bonding, anti-yellowing performance and long-term durability.

UV Adhesives for Brightness-Enhancement Films

To meet growing demand for brighter LCD displays with richer color, brightness-enhancement films help improve light efficiency. A micro-prism layer around 25 μm thick redirects light through refraction and reflection, reducing scattering and increasing brightness. The prism sheet is produced by coating UV-curable resin onto PET, embossing precise micro-structures and curing rapidly under UV light to form accurate optical patterns.
