Abstract
Coatings for a surface, especially a priming coating, of the present invention have been found to be durable, resistant to oxidative degradation, erosion and depolymerisation, stable to sterilization and low particulating, and are easily applied to the required surface of a substrate in a surface-independent manner. Such coatings, when used as priming coatings to be coated with a subsequent coating, in at least some embodiments, form exterior coatings which are also highly durable and are stable to sterilisation and aging.
Claims22
A surface having a coating comprising a mixture of components A and B, wherein
- component A is a polymer formed by self-polymerisation of a molecule comprising catechol functionality and amine and/or amide and/or hydroxyl functionality;
- and
- component B comprises a polymer comprising photosensitive or thermosensitive moieties at least some of which moieties form covalent bonds with component A and which polymer forms an interpenetrating network with component A.
A surface having a coating according to claim 21, wherein the surface is the surface of a substrate comprising a medical device.
