Hydrophilic Coatings
- Introduction
Hydrophilic Coatings for medical devices are lubricious, abrasion resistant, Non-thrombogenic and biocompatible.
Suitable for coating vascular catheters, guide wires and other medical devices, they can be applied to a wide range of polymeric
and metallic substrates
- Advantages
- Exceptionally hydrophilic
- Biocompatible
- Very thin, flexible coatings can be applied
- Lubricious when wet, preventing trauma and tissue abrasion
- Prevents adhesion of platelets, proteins, and microorganisms

- Properties
- Physical properties are readily adapted to meet the design criteria of medical device applications
- Thickness
- Storage stability
- Lubricity / flexibility
- Wettability
- Abrasion resistance

HA Coatings
- Introduction
- Noanix’s main hydrophilic coating solution uses hyaluronic acid, which is an FDA-approved natural polymer with excellent biocompatibility and low rejection reaction, so it is used in various fields of our body, such as ophthalmic supplements, intra-articular injections, artificial tears, and wound healing.
- HA is a kind of mucopolysaccharide, has a water content of 6000 times, is a method of attracting moisture in the air, and is stable as EWG 0 grade. In addition, it has high lubricity and durability, and was developed to be applied to various medical devices
