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.

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

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

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.

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%.

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

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.

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

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