Types of Medical Device Adhesives

Medical device Adhesives manufacturers use a variety of adhesive chemistries depending on the application. Common categories include:
● Epoxy Resins: Two-part epoxies provide strong, structural bonds and excellent chemical and heat resistance. PUCONS’s epoxy adhesives boast powerful adhesive strength and can cure at low or high temperatures as needed. These are used for bonding metal or hard plastics in applications like sensor housings or instrument casings.
● Instant (Cyanoacrylate) Adhesives: Single-component cyanoacrylate adhesives set in seconds without solvents. They work on a wide range of substrates (metal, glass, many plastics) and can be formulated with primers to bond difficult materials like polypropylene. PUCONS’s instant adhesive products deliver rapid curing and high bond strength for quick assembly of disposable tools or components.
● UV-Curing Adhesives: UV/UV-LED curable acrylates or epoxies cure in seconds under light, making them ideal for high-volume medical disposables. These adhesives offer strong bonds to metals and plastics and fast processing. For example, the PUCONS 3094J resin is a high-reactivity UV-curable adhesive with reduced shrinkage, specifically developed for medical device assembly. UV-curable adhesives are often used in bonding infusion sets, catheter components, and other parts where speed and precision are critical.
● Elastomeric (Silicone/Polyurethane) Adhesives: One-component, moisture- curing elastomers form flexible, durable seals. They are solventles and safe (DBT-free, tin-free). Silicone-based elastomeric adhesives are widely used to seal tubing, gaskets or enclosures where flexibility and biocompatibility are important. These adhesives cure into rubber-like elastomers that absorb stress and accommodate vibration in medical instruments.
Each type of adhesive is chosen for its unique combination of workability and performance in medical applications. The above categories cover most medical bonding needs, from rigid structural joints to flexible seals.
