  • POLYUREA COPOLYMER COATING COMPOSITIONS AND METHODS
    Publication number: 20250206980
    Abstract: Durable polyurea copolymer coatings can be applied to surfaces that come in contact with fluids, such as biological fluids, thereby passivating the surface. Polyurea copolymer coating compositions comprise a reaction product of (a) a diamine composition that includes a polyethylene glycol diamine, and optionally, a dipiperidyl alkane; (b) a diisocyanate; and (c) one or more photoreactive compounds, one or more biomolecules, or a combination of these. Solutions containing polyurea copolymers, coated surfaces and methods are also described.
    Type: Application
