Coating Requirements

If you’re experienced with lubricious hydrophilic coatings we make it easy to purchase them. There’s no licensing or royalty agreement attached to our products. If you’re not familiar with lubricious coatings, we’ll help you decide.

When considering a lubricious hydrophilic coating you’ll first want to ascertain what performance parameters are critical to success. The initial questions we always ask our customers:

What’s the surface (substrate/s) that needs to be coated?
How will the product or device be used?
How are you going to test performance?

Why? The hydrophilic coating needed is dependent on both the substrate to be coated and the specific use-case (application). We’ve created a coating selection tool to help you through this process. Now with that in mind, the performance characteristics below also influence the lubricious hydrophilic coating selection, and even more so, the coating process required.

Here’s what you’ll want to consider:

Lubricity

How slippery do you need it to be? This is typically measured by the coefficient of friction (CoF).

Durability

How long does the coating need to last? What conditions will it be exposed to? For example, if it is on a single-use device, like a cardiac guidewire, going through a complex anatomical pathway you want a coating that will be durable enough to handle a tortuous pathway; i.e., high wear resistance and resistant to shedding particulate.

Thickness

Are there specific thickness targets for your coating? Our hydrophilic coatings are typically hydrated by ~10 microns, and this can be adjusted up or down as a function of the specific hydrophilic coating and the coating protocol.

Cost

Before selecting a hydrophilic coating know the cost parameters (tolerances / constraints) you have per device/unit. Remember, total coating costs involve the product/s and the manufacturing costs. For example, eliminating the need for a primer can save significant costs by reducing manufacturing steps.

Biocompatibility

Is it touching a human? Blood? You will need to test your coated device to the ISO10993 biocompatibility standards. ISurTec coatings have been tested by third party labs to ensure that they will provide the biocompatibility you need.
