Medical Device Coating Types

Product Details

(Click to enlarge image) Because Formacoat is independent, we can work with a wide variety of coating types. These include:

Traditional Hydrogels:
The main class of hydrophilic coatings called "hydrogels." A hydrogel coating absorbs water and swells upon contact with water. These wetted polymers are what give these coatings their lubricous feel and excellent friction reducing properties.

Niche Hydrophilic coatings:
Micro-hydrophilic coatings: These are thinner coatings that do not swell appreciably on contact with water but that do present a robust hydrophilic surface that can be used in certain situations to good effect to reduce the contact angle on a substrate. They are not lubricity enhancing coatings.

Nano-hydrophilic coatings:
Do not swell on contact with water, so they are not lubricious but they can reduce the contact angle to good effect for certain specialized needs.

Nano-hydrophilic Plasma deposited nano-thickness coatings work on metal alloys. They are extremely durable and can coat ID's to tremendous length to ID ratios.

Nano-hydrophilic liquid applied coatings:
These nano-thicknesses, non-ceramic inorganic coatings, may work better on more substrates but as niche coatings have more limited applications.

Hydrophobic coatings:
Several Low temperature annealing varieties suitable for some applications.

These are not the classic, pigmented varieties that require high temperatures to anneal such as found on metal guidewires.
