Triboelectric coating powder and process |
摘要 |
An electrical chargeable dielectric coating powder and a triboelectric coating process for applying the powder to substrates are described. The coating powder is a mass of finely divided, heat fusible dielectric plastic material having an average particle size (My) of between 30 and 45 microns and a particle size distribution (all percents defined in weight percent) of: 95%-100% smaller than 88 microns, 5%-15% smaller than 15.56 microns and 0%-6% smaller than 11 microns. Preferably the coating powder has 0% larger than 88 microns and an Mv=about 30-40, preferably 35-40 microns. More preferably the particle distribution further includes 10%-15% smaller than 15.56 microns and 4%-6% smaller than 11 microns, and an Mv of between about 35 and 36 microns. Most preferably the particle distribution further includes: about 11.5% smaller than 15.56 microns and about 4.3% smaller than 11 microns, and an Mv of about 35.9. Preferably the powder is a thermosetting resin composition.
