Medical Devices

These one-part adhesives fixture in seconds at room temperature and are particularly suited for joining dissimilar substrates in almost any combination. They provide design advantages, speed assembly time, and increase production efficiency and quality.

LOCTITE^®’s high-performance structural adhesives provide high peel and shear strength on a wide variety of plastics, metals and glass. When cured, these thermoset plastics offer superior thermal and chemical resistance, as well as high cohesive strength and minimal shrinkage.

Henkel offers a complete line of dispensing, curing and process monitoring equipment designed specifically for use with our medical device adhesives.

As a manufacturer of the adhesive, dispensing and curing equipment, we understand the chemistry and the process needed to dispense and cure our products properly, so you can be assured of the highest quality, most cost-effective assembly with maximum bond strength and cure speeds.

Adhesives are universally used for bonding cannulae to hubs in needle assemblies. It is essential that the position of the cannula remains fixed and that this joint is well sealed to prevent fluids, such as blood or medicine, from leaking. Medical device manufacturers around the world have specified LOCTITE^® adhesives for more than four decades. The three most commonly used adhesive chemistries for needle manufacturing are: Light Cure Acrylics, Light Cure Cyanoacrylates and One-Part Heat Cure Epoxies. Henkel has developed products in all three chemistries that are ISO 10993 tested, have high pull strengths and fast cure times, and are highly fluorescent for automated in-line inspection.

LOCTITE^® medical grade adhesives have been developed for the bonding of typical catheter materials including PVC, polyurethane, polycarbonate and stainless steel. These adhesives are used to assemble the most challenging applications such as balloon to multi-lumen tubing, strain relief or transition of balloon to tube, drug-eluting stents and marker band bonding. The three most commonly used adhesive chemistries for catheter assembly are: Light Cure Acrylics, Cyanoacrylates and Light Cure Silicones. Henkel has developed products in all three chemistries that are ISO 10993 tested, have high pull strengths and fast cure times, and are highly fluorescent for automated in-line inspection.

LOCTITE^® light cure adhesives offer fast curing and excellent autoclave resistance in the manufacturing of tubes and connectors. Adhesives are used to assemble tubing to fittings, connectors, adaptors, IV sets, blood collection sets, drug infusion sets and feeding tubes. The three most commonly used adhesive chemistries for tube and connector assembly are: Light Cure Acrylics, Cyanoacrylates and Light Cure Silicones. Henkel has developed products in all three chemistries that are ISO 10993 tested, have high pull strengths and fast cure times, and are highly fluorescent for automated in-line inspection.

Whether you are producing large fluid storage reservoirs or small high-performance fluid monitoring devices, LOCTITE^® medical device adhesives provide structural bonds with superior gap filling and reliable sealing in combination with increased productivity. Common assembly applications for adhesives are blood oxygenators, blood filters, heat exchangers, blood bowls and blood pressure transducers. The two most commonly used adhesive chemistries for reservoir & enclosure assembly are: Light Cure Acrylics, and Cyanoacrylates. Henkel has developed products in both chemistries that are ISO 10993 tested, have high pull strengths and fast cure times, and are highly fluorescent for automated in-line inspection.

Henkel has extensive experience and knowledge of centrifugal potting processes and capabilities to assist with these critical applications. Henkel’s dialyzer solution portfolio includes customized products for specific application needs such as: low viscosity for optimal fiber bundle penetration, high adhesion to plastic housings, controlled exotherm for low shrinkage, as well as process optimization recommendations (centrifuge and trim times). Our solutions are tested in accordance with the generally accepted global ISO test standard 10993. Henkel’s complete offering for medical filtration applications such as oxygenators, dialyzers and filters includes polyurethanes, light cure acrylics, epoxies and water based solutions.

Henkel has extensive experience working closely with medical imaging equipment manufacturers. Henkel’s broad portfolio of high-performance solutions aligns with the many challenges faced: thermal resistance, thermal management, dissimilar substrates and robust strength requirements. Henkel technologies used for the assembly of key components of imaging equipment include anaerobics, cyanoacrylates, light cure acrylics, epoxies, polyurethanes, silicones and two-part acrylics.
