Polyurethane-based UV adhesive is a one-component ultraviolet light-curable adhesive made primarily from polyurethane acrylate oligomers, combined with reactive diluents and photoinitiators. It combines the rapid setting characteristics of light curing with the excellent flexibility and elasticity of polyurethane materials. After curing, the adhesive layer can be flexibly adjusted from extremely soft to semi-rigid, making it an ideal bonding solution for scenarios requiring impact resistance and bending resistance, such as flexible electronics and wearable devices.
Contact UsIts core advantage lies in its excellent elongation at break and flexibility, which can effectively absorb stress and resist fatigue failure caused by repeated bending. At the same time, it has fast curing speed, good transparency, and strong adhesion to various substrates such as plastics, glass, and metals. Through formulation adjustments, a wide range of hardness and viscosity can be achieved, meeting diverse needs from soft encapsulation to semi-rigid structural bonding.
??Flexible Electronics and Wearable Devices: Bonding of flexible screen bezels, potting protection for smart band/watch sensors, and assembly requiring bend resistance and low stress.
??Medical Devices: Bonding of components such as flexible catheters, breathing masks, and analgesic pumps that require skin contact and a soft feel, typically needing to meet biocompatibility standards.
??Electronics and Electrical Appliances: Impact-absorbing buffer bonding for smartphone camera modules, flexible encapsulation and stress relief for circuit board leads.
??Automotive and Security: Sealing of rearview camera sensors and tire pressure monitoring modules, flexible coating bonding for automotive interior dashboards, requiring excellent vibration resistance and impact resistance.
