EZ5101 PUR Adhesives for Electronics Touch Screen

The Advantages of Our Electronics Touch Screen PUR Adhesive

1. High-Precision Optical Bonding

Designed for electronic touch screen assemblies, our PUR adhesive supports high-precision optical lamination with light transmission above 90% and low yellowing characteristics. It helps maintain clear display quality, accurate visual presentation, and stable touch performance in demanding applications.

2. Excellent Environmental Resistance

The cured adhesive withstands thermal cycling from -40°C to 85°C and damp-heat aging at 85°C / 85% RH for 1,000 hours. It helps prevent delamination, bubble formation, and performance loss under long-term environmental stress.

3. Strong Mechanical Shock & Vibration Durability

Built for high-demand electronic assemblies, the adhesive maintains bond integrity under prolonged vibration and mechanical impact. It provides durable structural support for touch panels used in consumer electronics, industrial HMIs, home appliances, and medical control interfaces.

4. Broad Substrate Compatibility

Suitable for bonding cover glass (2.5D/3D), PMMA/acrylic lenses, PET/PC sensor films, OLED/LCD modules, and metal or plastic frames. It supports multiple process steps including display lamination, touch sensor bonding, decorative frame mounting, EMI shielding and grounding, and structural sealing.

5. Clean Manufacturing & Low VOC

The solvent-free formulation offers low curing shrinkage, minimal odor, and low VOC emissions. It reduces waste and rework while ensuring consistent flow, wetting, and process stability for continuous automated production.

Key Process Description

1. Heating & Preparation

The PUR adhesive is heated to the recommended operating temperature to achieve stable flowability for precise dispensing and controlled bonding in touch panel production.

2. Precision Application

It is applied uniformly onto the glass, sensor film, module surface, or frame area to ensure even wetting and accurate adhesive distribution without excessive overflow or optical contamination.

3. Panel Assembly & Positioning

During the assembly process, the bonded layers are positioned under controlled pressure to achieve reliable integration of optical, touch, and structural components while reducing misalignment and assembly defects.

4. Moisture-Curing Crosslinking

After bonding, the adhesive reacts with ambient moisture to form a durable 3D cross-linked thermoset structure. This ensures long-term resistance to heat, humidity, vibration, chemical exposure, and aging.

Benefits in Touch Panel Applications

Consumer Electronics

Ideal for touch screens used in smartphones, tablets, wearable devices, and smart home products that require clear display effect, reliable bonding strength, and compact structural design.
