A method includes forming an antimicrobial blend including an antimicrobial additive combined with a polymer, and forming a medical device with the antimicrobial blend, wherein a surface of the medical device exhibits antimicrobial properties.

Modified lignin products, processes for making them, and their use to produce rigid polyurethane or polyisocyanurate foams are disclosed. The processes comprise heating a lignin source with a nitrogen source and a starved concentration of a C.sub.1-C.sub.5 aldehyde to give a reaction mixture comprising a Mannich condensation product, neutralizing the reaction mixture, and isolating the modified lignin product. The process is performed at a mass ratio of lignin source to nitrogen source within the range of 1:1 to 1:5 and at a molar ratio of nitrogen source to C.sub.1-C.sub.5 aldehyde within the range of 3.5:1 to 1:1. Polyol blends and performance additives that contain the modified lignin products are described. Rigid foams that process well and incorporate up to 60 wt.%, based on the amount of polyol component, of the modified lignin contribute to excellent flame retardancy and low-temperature R-value performance.

The present invention provides for a composition comprising a pigment, wherein the composition is suitable for coating a surface that is, or is expected to be, exposed to the sun. The pigment comprises particles that fluoresce in sunlight, thereby remaining cooler in the sun than coatings pigmented with non-fluorescent particles. The particles comprise solids that fluoresce or glow in the visible or near infrared (NIR) spectra, or that fluoresce when doped. Suitable dopants include, but are not limited to, ions of rare earths and transition metals. A coating composition includes: (i) a film-forming resin; (ii) an infrared reflective pigment; and (iii) an infrared fluorescent pigment different from the infrared reflective pigment. When the coating composition is cured to form a coating and exposed to radiation comprising fluorescence-exciting radiation, the coating has a greater effective solar reflectance (ESR) compared to the same coating exposed to the radiation comprising fluorescence-exciting radiation except without the infrared fluorescent pigment. A multi-layer coating including the coating composition, and a substrate at least partially coated with the coating composition is also disclosed. A method of reducing temperature of an article includes applying the coating composition to at least a portion of the article.
