Epoxy resin medical assembly adhesive UV26DCMed

epoxyfor medical devicesfor ceramics

Overview
One-component, dual-cure (UV + heat) epoxy system formulated for medical device bonding and sealing; passes ISO 10993-5 for cytotoxicity.

Key Features

• Low viscosity for good wetting and dispensing
• Minimal shrinkage on cure to maintain dimensional stability
• High optical clarity for transparent assemblies
• Heat-curing capability (110–125°C) ensures cure in shadowed or masked areas

Typical Properties

• Viscosity: Part A: 500–3,500 cps (Part B not specified)
• Hardness: 80–90 Shore D
• Service temperature range: -60°F to +500°F
• Dielectric constant: 3.85
• Glass transition temperature (Tg): 160–170°C

Cure Schedule
Initial UV exposure at 320–365 nm with 20–40 mW/cm² induces rapid surface cross-linking. Apply heat at 110–125°C for 60–90 minutes to complete polymerization in non‑exposed areas. A post cure at 120–150°C for 1–2 hours is recommended to optimize mechanical strength, chemical resistance, and Tg.

Product Description
Master Bond UV26DCMed is a one-component, dual-cure epoxy designed for medical applications where reliable bonding and sterilization resistance are required. UV light provides fast cure on exposed surfaces while heat completes cure throughout complex geometries. The formulation resists a wide range of sterilants (including ethylene oxide, glutaraldehyde and multiple hydrogen peroxide systems such as STERRAD™) and endures repeated steam autoclaving.

Product Advantages

• No mixing—single-component handling
• Effective cure in shadowed areas with heat
• No oxygen inhibition—consistent surface cure
• High mechanical strength and dimensional stability
• Withstands repeated sterilization cycles including autoclaving
• Passes ISO 10993-5 for cytotoxicity

Applications

• Bonding of metals, glass, ceramics and most plastics
• Sealing of assemblies requiring sterilization resistance
• Manufacture and repair of reusable medical instruments

Certifications

• ISO 10993-5 for Cytotoxicity
• Complies with EU Directive 2015/863 (RoHS)

Packaging

• Can
• Syringe
