Fluid Coating

When it comes to coating medical devices, EFD (a Nordson subsidiary) low-volume, low-pressure valves provide the precise, repeatable application demanded by the industry. Today, many more medical devices are being coated with fluids in unconventional ways, and EFD valves bring speed and efficiency to the process. For example, drug eluting stents are coated with drugs and polymers, and prosthetics are frequently coated with anti-infection drugs and lubricious coatings

Today, manufacturers routinely coat catheters with lubricious and other coatings. Catheters are flexible, but tend to have low surface coefficient, which inhibits transport through the body's highway system of veins and arteries.  By coating a catheter with a hydrophillic coating, it can easily travel through the body.  When the coating comes in contact with blood or other body fluid, it also becomes very slippery – almost jelly-like.  As a result, the coating can also inhibit blood coagulation.  Due to the thin consistency of the coating, all these benefits can be achieved without adding thickness to the catheter diameter. 

As the use of hot melt adhesives for transdermal drug delivery becomes more prevalent, Nordson coating and extrusion systems can provide an unmatched level of control.  This offers significant benefits for systems that involve active ingredients, such as transdermal patches.

For every application, Nordson and its affiliates provide the most advanced dispensing technology and process expertise, resulting in the highest reliability for our customers' products.
