Abstract: The present teachings include powder coating including a plurality of core/shell particles. Each particle of plurality of core/shell particles has a size of from about 3 microns to about 100 microns. Each particle of the plurality of core/shell particles has a core including a cross-linkable crystalline polyester resin having a melting temperature of less than about 150°C. Each particle of the plurality of core/shell particles has a shell including a cross-linkable amorphous polyester resin having a glass transition temperature greater than 40°C. Each particle of the plurality of core/shell particles includes a thermal initiator.

Abstract: Melt emulsification may be employed to form elastomeric particulates in a narrow size range when nanoparticles are included as an emulsion stabilizer. Such processes may comprise combining a polyurethane polymer and nanoparticles with a carrier fluid at a heating temperature at or above a melting point or a softening temperature of the polyurethane polymer, applying sufficient shear to disperse the polyurethane polymer as liquefied droplets in the presence of the nanoparticles in the carrier fluid at the heating temperature, cooling the carrier fluid at least until elastomeric particulates in a solidified state foini, and separating the elastomeric particulates from the carrier fluid. In the elastomeric particulates, the polyurethane polymer defines a core and an outer surface of the elastomeric particulates and the nanoparticles are associated with the outer surface. The elastomeric particulates may have a D50 of about 1 [im to about 1,000 m.

Abstract: Die vorliegenden Lehren umfassen eine Pulverbeschichtung mit einer Vielzahl von Kern-Schale-Partikeln. Jeder Partikel aus einer Vielzahl von Kern-Schale-Partikeln hat eine Größe von etwa 3 Mikrometern bis zu etwa 100 Mikrometern. Jeder Partikel aus der Vielzahl von Kern-Schale-Partikeln hat einen Kern, der ein vernetzbares kristallines Polyesterharz mit einer Schmelztemperatur von weniger als etwa 150 °C enthält. Jeder Partikel aus der Vielzahl von Kern-Schale-Partikeln hat eine Schale, die ein vernetzbares amorphes Polyesterharz umfasst, das eine Glasübergangstemperatur von mehr als 40 °C aufweist. Jeder Partikel aus der Vielzahl von Kern-Schale-Partikeln umfasst einen thermischen Initiator.
