Touch Panel
Electronics Touch Screen PUR Bonding Solutions

PUR (Polyurethane Reactive) hot melt adhesives deliver superior bonding performance in electronic touch screen assemblies for high-demand applications. They provide excellent resistance to environmental stress, aging, and mechanical shock while enabling high-precision optical lamination processes. These solutions are ideal for use in consumer electronics, home appliances, industrial HMIs, and medical touch interfaces.


Materials

Compatible Substrates

Cover Glass (2.5D/3D) | PMMA/Acrylic Lens | PET/PC Sensor Film | OLED/LCD Modules | Metal/Plastic Frames


Key Applications

Display Lamination | Touch Panel Sensor Bonding | Decorative Frame Mounting | EMI Shielding & Grounding | Structural Sealing


Core Advantages
Durability in Demanding Environments

Resists thermal cycling (–40°C to 85°C), damp heat (85°C/85% RH, 1000 hours), and chemical exposure. Maintains bond integrity under prolonged vibration and mechanical impact.


Optical Clarity & Process Compatibility

Low yellowing index and light transmission exceeding 90%; minimal odor and VOC emissions. Compatible with automated dispensing and rapid curing processes.


Manufacturing Efficiency

Solvent-free formulation with low curing shrinkage reduces waste and rework. Enables continuous production with consistent flow and wetting properties.
