HydrophilicCoating Trends:  Coatings, Coaters and Curing

Coatings, Curing, Coaters

Discover the science behind applying and curing hydrophilic coatings to medical devices.  Listen to our distinguished panel of experts, as they address the topics of Coating Solutions, Application Equipment, and UV Curing advancements.

Hydrophilic Coating Solutions

LVDBiotech’s hydrophilic coating solution provides a reduction of friction, improves pushability, trackability, and crossability. The coating is biocompatible, non-cytotoxic and does not induce thrombogenicity.  It is designed to enhance the use of the medical device by the specialist, and brings advanced navigation, taking the physical and mechanical properties of the device to the maximum.

Listen to this presentation to learn:

  • Which coating solution is right for you?  
  • How to achieve a uniform application
  • Learn about plasma treatment and how the process works.
In which substrates can we use the hydrophilic coating?

Hydrax is suitable for a wide variety of substrates: Nylon, Pebax, PVC, HDPE, polypropylene (PP), silicone, etc. Nylon and Pebax are materials used to manufacture coronary and peripheral catheters, while in urology the tubes are mainly made of PVC, PP and silicone.

What is the standard coating process time?

Our process is based on dipping the device in the solution and then curing by UV light, in particular UV-C. It takes between 5 to 15 minutes for a batch of 8 to12 devices. Steps: cleaning the substrate, primer dipping (soaking, extraction, curing time), top coat dipping (soak, extraction, curing time). The time in which UV is applied changes in each type of application

What tests verify the coated device?

Friction test (durability and friction), particulate matter release (specially important for cardiovascular and peripheral devices because the device can not releases particles to the bloodstream). LVD Biotech offers a wide range of testing and evaluation methods that meet our customers’ requirements

Revolutionary 3D Curing:

Take a listen to this in-depth discussion that will transform the way you approach your catheter curing processes.  


  • Equal Exposure for Enhanced Results: All surfaces are exposed to precisely the same amount of UV light, eliminating inconsistencies.
  • StreamlinedProcess: No rotation or lamp motion required. .
  • ContinuousMonitoring for Precision: How an innovative technology continuously monitors UV irradiation during the exposure process, ensuring unmatched accuracy and quality control.
  • How to achieve repeatable exposure part-to part and batch-to-batch.
What is the uniformity in the chamber, and how do you verify it?

Typically+/-5%. We verify it using spectrometer measurements at various points on the chamber wall as well as by hanging small radiometers from the catheters themselves at various points with various fields of view.

How is uniformity effected by number of catheters?

ForPTA-type catheters, there is no effect because these parts are small diameter and generally have large spacing between. For urinary catheters, the diameter is much larger and spacing is much closer. So, we do see a degradation in uniformity up to +/- 10%.

How does the catheter penetrate the chamber during cure? Will it touch my catheters?

We have small slots in the chamber top to allow the hanging catheters to enter the chamber without touching the chamber itself.

Dip Coating Equipment

Discover the technology incorporated into the latest catheter dip coating equipment and how a decade of iterative engineering results in the optimal solution for your hydrophilic and ultraviolet-curing processes.

During this webinar you’ll learn about:

  • Production Scale Coating
  • 360 UV Curing
  • Hydrophilic Coating Fluid Management
  • Building Process Recipes
Can you coat products for longer than 500mm?

The2269 is the off the shelf machine for 400mm, with the new concept its 500mm asa standard. But we have built machines with coating lengths up to 1000mm. Coating and Product length can be fitted to the customer needs.

Is there an extraction needed?

With the solutions so far it was not necessary but there’s the option to connect the machine to one.

What is a typical process time or what is the reduction of a average process with vela in percentage?

You can expect a 25 – 50% reduction in cure time.
