Hydrophilic Coating

Hydrophilic coating has the characteristics of affinity for water.

Chemically, this means that the coating participates in dynamic hydrogen bonding processes with water in the device environment. In most cases, the hydrophilic coating is also ionic and usually has a negative charge, which will be more conducive to the interaction with aqueous solutions.

From a physical standpoint, the chemical interaction between the coating and water creates a gel material that exhibits an extremely low coefficient of friction. Collectively, these chemical and physical properties characterize a material that is wettable, lubricious, and suitable for specific biological interactions, currently used primarily in interventional medical devices.

The ultrasonic drug-eluting stent spray coating system can be applied to the preparation of polymer coating for preventing vascular restenosis on the surface of implantable drug-eluting stent. Compared to conventional two-fluid nozzles, ultrasonic nozzles can spray a more uniform drug coating that completely covers the stent without the orange peel and adhesion to a complex stent. The soft atomized spray adheres well to surfaces and coating morphology characteristics can be adjusted by modifying process parameters. In addition, the stent coating obtained by ultrasonic spray coating technology is thinner than dip-coating. Ultrasonic spray coating technology can precisely control the amount of drug sprayed on the stent, making the control of the spraying more precisely.
