Abstract:

Methods for imparting a texture to a cured powder coated surface are provided. These methods involve heating the cured powder coating to a temperature greater than its glass transition point (T), then imparting a texture to the cured powder coating under pressure using a release medium having a replicative surface. After the texture is imparted to the cured powder coating, the release medium can be removed. Examples of suitable release media include, for example, engraved plates, engraved rolls, release papers, release films, and release webs.
