HydroMed is a series of ether-based hydrophilic urethanes with excellent adhesive and cohesive properties.
This product line exhibits tailored water absorption levels depending upon end product targets. These materials were designed for use as coatings for a wide array of devices including catheters, guidewires, sutures, introducers, rods, and valves. Additionally, HydroMed does not require UV curing and as such, provides a superior alternative to UV curable materials for devices which require inner lumen or complicated form coatings.
The HydroMed series can also be coated onto devices to reduce the absorption of white blood cells and proteins, thereby aiding in the analysis of blood and DNA.
HydroMed is processed by traditional solvent coating methods. The polymer granules can be dissolved in varying concentrations using most organic and inorganic solvent packages.

ASB provides each of the HydroMed grades in solution form using various solvent packages. Based upon individual device requirements, custom formulations can be developed to provide targeted lubricity, adhesion and thickness levels.
HydroMed solutions can be dip coated or spray coated. In the former, it is recommended to submerse into the solution for 3 to 20 seconds. The solvent will evaporate under normal, non-humid room temperatures within 3 to 30 minutes, depending upon concentration, solvent used and coating thickness.
Alternatively, the component can be oven heated up to 80°C for 2 to 15 minutes, depending on coating thickness, solvent choice and material substrate to expedite removal of the solvent.
This material does not require UV curing and as such, provides a superior alternative to UV curable materials for devices which require inner lumen or complicated form coatings.
