Medical Device Coatings

Medical Device Coatings

ISurTec’s coating technologies enable vascular catheters, guide wires and other medical devices to navigate through the most challenging anatomies, helping create safer and easier treatments.

If you have a particularly unique application let us know. ISurTec has extensive experience in creating custom coatings for unique applications and substrates.

ISurGlide Hydrophilic Lubricious Coatings

ISurTec offers pre-mixed coating formulations for easy in-line manufacturing. ISurGlide coatings can be applied as a single or double layer, with or without a primer, to meet the performance requirements for your device.  You may also tailor your coating viscosity to create a coating process that works within your specific manufacturing system.

ISurGlide® Plus: Our newest coating technology. Designed to eliminate the need for priming and therefore save significant manufacturing time and cost.

ISurGlide® 460 Family: Our most popular coating. Available in 3.5%, 4.5%, and 7.5% total dissolved solids.

ISurGlide® 200.85: High-viscosity coating solution formulated for small-diameter devices. Commonly used on coronary and vascular guidewires.

ISurGlide® 475: Medium-viscosity coating formulated with a longer dry-out time for long-lasting wettability. Best as a single-layer application in materials that do not require priming. Commonly used on urinary devices.

PhotoPrime® Family of Primers

Some substrate materials benefit from priming the surface to improve adherence to a lubricious coating. In these instances, application of our patented primer coating creates a uniform, compatible surface that enables durable bonding of the subsequent ISurGlide coating.

PhotoPrime® primers use photochemistry to modify the surface of a device. The primer’s photoreactivity increases the crosslinking density and gives the coating system its strength and durability. They are applied using dip/UV cure procedures similar to those used to apply our ISurGlide products nearly identical to the procedure for our ISurGlide products.

PhotoPrime® primers have been used successfully to enable durable coatings on nylon, Grilamid®, all durometers of PEBAX®, polyurethane, low-density polyethylene, high-density polyethylene, polyester, polypropylene, silicone rubber, silicon, and metal.

PhotoPrime®SR 330 Our newest primer technology. Designed to enable coating of challenging substrates, such as silicone rubber, stainless steel, nitinol, aluminum, PEEK, HDPE, ceramics, silicon, silicon nitride, and other common semiconductor substrates.

PhotoPrime® 955 Our most popular primer. Formulated in isopropyl alcohol.

PhotoPrime® 150 Formulated in acetone for low surface energy, hard-to-wet, difficult-to-coat substrates. PhotoPrime 150 is used when extra durability is desired in sensitive applications, such as neurovascular catheters.

ISurTec is a technology innovator with a deep passion for identifying, creating and commercializing new methods and products that enable companies to fulfill their mission.
