  • Patent number: 9623156
    Abstract: A method of coating surfaces of various body-implantable materials with control-releasable nitrogen monoxide using a catecholamine, more particularly, technology of preparing a coating film containing a diazeniumdiolate functional group on a surface of a material to be coated using a catecholamine, is provided. The coating film prepared by the method has advantages in that nitrogen monoxide can be stably supplied under an in vivo environment, and can be suitably used in a living body without causing cytotoxicity. Therefore, among the materials having a coating film formed on a surface thereof, the body-implantable material is especially expected to be widely used for medical and health applications including treatment of ischemic disorders such as arteriosclerosis through controlled release of nitrogen monoxide, regulation of penile erections, antibacterial and antiviral effects, and wound healing.

  • Patent number: 8883931
    Abstract: The present invention relates to polyfunctional nitrones (optionally in the form of nitrone-terminated polymers) and to their use as crosslinking agents and matting agents, preferably for producing stable molding compounds, knifing fillers, and use thereof in inks, coatings, and adhesives. Low crosslinking temperatures characterize the invention. Through the use of polyfunctional nitrones it is possible for all unsaturated polymers to be cured, solidified and/or structured at low temperatures, preferably without use of a catalyst. Depending on the amount of nitrone-terminated polymers and/or low molecular mass polyfunctional nitrone used it is possible to exert a strong influence over the optical and the mechanical properties of the coated surfaces. By optical properties are meant, among others, the gloss of the coating systems and the surface structuring, e.g., the matte effect.

  • Publication number: 20100273910
    Abstract: The present invention relates to polyfunctional nitrones (optionally in the form of nitrone-terminated polymers) and to their use as crosslinking agents and matting agents, preferably for producing stable molding compounds, knifing fillers, and use thereof in inks, coatings, and adhesives. Low crosslinking temperatures characterize the invention. Through the use of polyfunctional nitrones it is possible for all unsaturated polymers to be cured, solidified and/or structured at low temperatures, preferably without use of a catalyst. Depending on the amount of nitrone-terminated polymers and/or low molecular mass polyfunctional nitrone used it is possible to exert a strong influence over the optical and the mechanical properties of the coated surfaces. By optical properties are meant, among others, the gloss of the coating systems and the surface structuring, e.g., the matt effect.
