ELECTROSTATIC POWDER COATING OF ELECTRICALLY NON-CONDUCTING SUBSTRATES

摘要

A powder coating method includes applying an antistatic material to the surface of an electrically nonconducting substrate. The antistatic material is preferably a fatty amine salt and is applied by spraying. A flow of electrostatically charged powder particles is directed toward the substrate to form a powder coating on the substrate, and the powd er coating is thereafter cured.
