Typical examples of thermoplastic powder coatings

thermoplastic powder coatings

A thermoplastic powder coating melts and flows on the application of heat, but continues to have the same chemical composition when it solidifies on cooling. Thermoplastic powder coatings are based on thermoplastic resins of high molecular weight. The properties of these coatings depend on the basic properties of the resin. These tough and resistant resins tend to be difficult, as well as expensive, to be ground into the very fine particles necessary for the spray application and fusing of thinRead More …

Three primary resins used in thermoplastic powder coatings

There are three primary resins used in thermoplastic powder coating, vinyls, nylons and polyesters. These materials are used for some food contact applications, playground equipment, shopping carts, hospital shelving and other applications. Few of the thermoplastics have the broad range of appearance properties, performance properties and stability that are required in applications that use thermoset powders. Thermoplastic powders are typically high molecular weight materials that require high temperature to melt and flow. They are commonly applied by fluidized bed applicationRead More …
