Product Introduction

Designed for high-speed production, this adhesive bonds rigid/flexible PVC to polycarbonate without inducing stress cracks. Ideal for disposable medical devices with gaps <0.25 mm, it also adheres to glass, metals, and diverse plastics. Achieves fixture in 5 seconds under UV light (365nm @100mW/cm²).

Product Special Attributes

Unique >13mm depth of cure (100mW/cm² UV, 30 sec) enables thick-section bonding. Maintains 100% strength after 340h @93°C and steam autoclave sterilization. Superior flexibility: 265% elongation at break with 23 N/mm² tensile strength. Dielectric strength 31 kV/mm supports electronic medical devices.

Application Scenarios

Critical for IV set connectors (PVC-polycarbonate), blood filtration housings, and wearable medical sensors (per Henkel medical solutions portfolio). Extensively used in insulin pump assemblies and microfluidic lab-on-chip devices requiring biocompatibility and rapid curing.
