When it comes to using LOCTITE^® adhesives in medical disposable device assemblies, Henkel offers a wide portfolio of medical device adhesives that meet ISO 10993 biocompatibility standards. Applications include, needles, syringes, catheters, tubes, connectors, and more. Henkel also offers light cure adhesives formulated with focus on safer ingredients for use in medical devices including wearables. They are tested to Henkel’s protocols based upon ISO 10993 biocompatibility standards (ISO 10993-5,-10,-11,-4,-6). For more information on these adhesives, click here.

Without any doubt, the coronavirus pandemic has put us all in an exceptional situation. At Henkel, we are doing everything in our power to safeguard our employees, support our customers and suppliers, and reduce the spread of the virus. For information on related applications see adhesives used in assembly of PPE & respiratory devices.

In addition to offering highly reliable and cost-effective medical device adhesives, Henkel’s team of skilled engineers and adhesive specialists are on hand to help you find the best solutions to fit your needs.

Needles and Syringes

Medical device adhesives are universally used for bonding cannula to hubs in needle assemblies. It is essential that 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 in trillions of needles and syringes.

The three most commonly used adhesive chemistries for needle bonding and manufacturing are: Light Cure Acrylics (both UV cure and LED cure), 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.

Catheters

LOCTITE^® medical device adhesives are designed for bonding 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 (UV and LED light cure) Cyanoacrylates, and Light Cure Silicones. 

Henkel has developed products in all three chemistries that are ISO 10993 tested, have high pull strengths combined with high or low flexibility, enable fast cure times, and are highly fluorescent for automated in-line inspection.

Tubes and Connectors

LOCTITE^® light cure adhesives offer the performance combination of fast cure, proper adhesion, high strength and adapted flexibility for 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, Light Cure Cyanoacrylates, and Light Cure Silicones.

Henkel has developed products in all three chemistries that have been tested to ISO 10993 biocompatibility standards, have high pull strengths and fast cure times, and are highly fluorescent for automated in-line inspection.

Blood Filtration

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 medical device adhesive 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, and epoxies.

Respiratory, Prosthetics, Surgical Tools, and Endoscopes

LOCTITE^® medical device adhesives offer reliable, fast curing assembly solutions for respiratory, prosthetics, surgical tools and instruments, endoscopes, and many other disposable and non-disposable devices. They enable high speed production, in-line control and the ability to assemble a range of materials including plastics that can be difficult to bond or weld. The most commonly used adhesive chemistries for these applications are: Light Cure Acrylics, Cyanoacrylates, Light Cure Cyanoacrylates, and Light Cure Silicones. 

Henkel has developed products in these chemistries that are ISO 10993 tested, clear, colorless, fast curing, and highly fluorescent for automated in-line inspection.

Imaging Equipment

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 the wide range of standards adhesives, including anaerobics, cyanoacrylates, light cure acrylics, epoxies, polyurethanes, silicones and two-part acrylics, the range of adhesives of electronic assemblies, as well as the range of biocompatible adhesives.

Light Cure Adhesives for Medical Devices

Henkel’s light cure adhesives for medical devices offer a number of benefits such as their ability to cure quickly, as well as providing excellent strength and durability. Henkel offers a product portfolio that includes light cure acrylic adhesives for medical devices, light cure cyanoacrylate for medical devices light cure silicones for medical devices.

Henkel’s wide range of acrylic medical adhesives include UV and LED cure adhesives that are ideal for use in a wide range of medical applications including tube assemblies, connectors, and housing.

Cyanoacrylates for Medical Devices

Cyanoacrylate medical adhesives exhibit extremely high adhesion properties and are highly resistant to a wide range of chemicals and solvents. They are also known as instant adhesives and provide strong bonding to a variety of substrates, including elastomers. Recent developed grades offer high elongation of 30% for bended or flexed assemblies, and fluorescence for inspection. With easy to dispense characteristics, cyanoacrylate adhesives for medical use enables medical device manufacturers to speed up assembly processes while continuing to offer safe and reliable products.
