Applications for UV Light Curable Adhesives in Medical Device Assembly:

• Bonding Dissimilar Materials: Effectively adhere plastics, metals, and glass substrates commonly used in medical devices.
• Catheter Assembly: Secure cannulas, balloons, and other components for reliable catheter function.
• Syringe Assembly: Create strong bonds for syringes and other fluid handling devices.
• Microfluidic Device Assembly: Precisely bond microfluidic components for accurate and reliable fluid flow.
• Sensor Attachment: Securely attach sensors to various device components for accurate data collection.

Choosing the Right UV Light Curable Adhesive:

Selecting the optimal UV curable adhesive for your medical device assembly requires careful consideration of several factors:

• Material Compatibility: Ensure the adhesive bonds seamlessly with your specific materials (e.g., polycarbonate, stainless steel, silicone).
• Viscosity: Opt for high viscosity for gap filling or lower viscosity for easier application on delicate microfluidic components.
• Curing Speed: Balance curing speed with production line needs, avoiding overly rapid curing that limits repositioning flexibility.
• Light Source Compatibility: Match the adhesive’s curing wavelength with your UV light source for optimal performance.
• Biocompatibility: Select adhesives that meet relevant biocompatibility standards (e.g., USP Class VI) for safe patient use.
• Sterilization Compatibility: Choose adhesives compatible with your chosen sterilization method (e.g., autoclave, EtO).
