Estimating the term…
The invention relates to a hydrophilic coating formulation which when cured results in a hydrophilic coating, wherein the hydrophilic coating formulation comprises a polyelectrolyte and a non-ionic hydrophilic polymer. The invention further relates to a coating system, a hydrophilic coating, a lubricious coating, use of a polyelectrolyte and a non-ionic hydrophilic polymer in a lubricious coating, an article, a medical device or component and a method of forming on a substrate a hydrophilic coating.
Hydrophilic coating formulation which when cured results in a hydrophilic coating, wherein the hydrophilic coating formulation comprises a polyelectrolyte and a non-ionic hydrophilic polymer.
Lubricious coating having an initial lubricity after 1 cycle as measured on a Harland FTS Friction Tester of 20 g or less.
Coating system for preparing a lubricious coating, said coating system comprising a coating formulation comprising a non-ionic hydrophilic polymer and a wetting fluid comprising a polyelectrolyte.
Use of a polyelectrolyte and a non-ionic hydrophilic polymer in a lubricious coating in order to improve the dry-out time of the lubricious coating, wherein dry-out time is defined as the duration of the coating remaining lubricious after a device comprising the lubricious coating has been taken out of the wetting fluid wherein it has been stored and/or wetted, which is determined by measuring the friction in g as a function of time on a Harland FTS Friction Tester.
