Technologies and Processes
- LOCA Bonding with UV-Acrylates: We use Liquid Optically Clear Adhesives (LOCA) with UV-curing acrylates. This technology allows us to achieve perfect optical clarity and excellent adhesion. UV curing ensures fast and uniform bonding, ideal for high-resolution displays and touchscreens, eliminating reflections and air bubbles while enhancing readability in direct sunlight.
- OCA (Optically Clear Adhesive): In addition to LOCA, we also offer the use of Optically Clear Adhesive (OCA) films. These self-adhesive films feature excellent optical clarity and ease of handling. OCA is particularly suitable for applications requiring precise alignment and uniform adhesion.
- Real Glass and Transparent Plastic Applications: Our Optical Bonding solutions include both real glass and transparent plastics. This allows us to develop customized solutions for a wide variety of applications, from industrial displays to medical screens. The use of real glass provides high scratch resistance and optical clarity, while transparent plastics offer lightweight and flexible solutions.
