Medical Device Hydrophilic Coatings
UV-Curable
Hydrophilic Coatings
Hydromer®’s proprietary UV-curable, hydrophilic coating technology delivers a smooth, low-friction surface that enhances device navigability, procedural precision, and patient safety by reducing tissue trauma.
What our formulations do
Advantages of Product
Formula Safety
The coating formula demonstrates excellent biocompatibility, using non irritating solvents and PVP (polyvinylpyrrolidone) as its primary component.
Easy Customer Registration
With an FDA filing number, our coatings are widely registered and accepted by CE, CFDA, and various other global regulatory authorities.
Balanced Lubricity & Durability
Our coatings provide an ideal balance between lubricity and durability, with performance adjustable through precise parameter control.
High Flexibility
The coating maintains integrity under bending and curved-path applications without cracking or peeling.
Low Particulate Release
Engineered for patient safety, our coatings demonstrate exceptionally low particulate release within regulatory standards, while maintaining superior lubricity and long-term durability.
Sterilization Compatibility
Compatible with both ethylene oxide (EO) and electron beam (E-beam) sterilization methods.
Performance Tests
Hydromer hydrophilic coatings can reduce the coefficient of friction of a wide range of substrates by more than 95%, dramatically improving device pushability and trackability.
Microscopic analysis confirms that Hydromer-coated device surfaces are smooth, continuous, and highly uniform, even on complex geometries.
Featured Application Cases
Application on Metal Devices:
The unique structure and mechanical requirements of metal spring guidewires place stringent
demands on surface coatings.
Hydromer’ s metal-optimized hydrophilic coatings provide excellent lubricity and strong adhesion
while preserving the guidewire’ s intrinsic properties, including flexibility, torque response, and tip
malleability.
Application on Braided Tubing:
The complex architecture of braided tubing presents challenges for coating durability, particularly
under repeated mechanical stress.
Hydromer delivers advanced lubricious hydrophilic coating solutions that enhance surface durability
and coating retention without compromising the functional performance of braided structures.

Product Advantages
Hydromer’s hydrophilic medical device coatings offer lubricity, low particle content, enhanced adhesion, thrombogenic resistance, and durability.
Hydromer® Thermal-Curable Coatings are a powerful complement to traditional UV systems and the preferred solution for complex-structure medical devices.
Covers Complex Device Structures
Thanks to uniform thermal energy penetration, thermal-curable technology enables consistent coating of narrow lumens, multi-lumen tubing, and intricate geometries, forming continuous, defect-free coatings even in challenging designs.
Superior Inner-Lumen Lubrication
Thermal-curable coatings excel in internal surface applications. Thermal curing allows deep penetration into long and narrow lumens, delivering true full-length inner-wall lubrication with stable adhesion.
High Adhesion and Wear Resistance
Through specialized crosslinking mechanisms, Hydromer thermal-curable coatings form robust, highly adherent layers after curing. These coatings exhibit strong wear resistance and are well-suited for high-load and repeated-use scenarios.
Hydromer® hydrophilic medical device coatings combine:
Hydromer® thermal-curable coatings serve as a powerful complement to UV curable systems and are the preferred solution for devices with complex structures.
Performance Validation
Dynamic friction testing demonstrates that Hydromer® thermal-curable coatings provide:
Low friction coefficients, significantly reducing insertion resistance and improving device control
High wear cycle durability, maintaining coating integrity after repeated insertion and withdrawal
Strong adhesion, resistant to peeling or cracking under bending and stress concentration
Performance Validation
Hydromer® Thermal-curable coatings exhibit low particle counts at ≥10 μm, ≥25 μm, and ≥50 μm thresholds, meeting stringent medical device particulate standards and ensuring safe in-vivo use.
