Lubricious silicone coatings for catheters, needles & guidewires
Solution essentials
- Dispersion vs fluid: dispersions cure to a durable bonded lubricious film; fluids give immediate low-friction siliconization where a cured film isn't required.
- Substrate: match the dispersion and any primer to the substrate (PVC, PU, Pebax, nylon, metal, glass) for adhesion.
- Process: dip or wipe to a controlled thickness, then cure per the data sheet; control coat weight for consistent lubricity.
- Compliance: select restricted/unrestricted by contact type and duration; documentation per device.
What BIO provides
BIO provides selection, process support and supply of NuSil / Avantor lubricious dispersions and silicone fluids for China catheter, interventional and injection-device makers.
FAQ
What gives a catheter its lubricious silicone coating?
Either a curable silicone dispersion that forms a durable bonded low-friction film, or a silicone fluid for siliconization. Dispersions are chosen when the coating must endure repeated use.
How is the coating applied?
Typically dip or wipe to a controlled thickness, then cure per the data sheet. Controlling coat weight and cure is what gives consistent, repeatable lubricity.
How do you get the coating to adhere to the substrate?
Match the dispersion (and primer if needed) to the substrate — PVC, polyurethane, Pebax, nylon, metal or glass each behave differently; surface prep may be required.
