Electrostatic deposition of charged coating particles onto a dielectric substrate |
摘要 |
This invention provides a process for electrostatically applying a coating composition onto dielectric materials which have a dielectric constant less than 4.0. In this process, a positive charge is induced onto a coating composition. The dielectric material is electrically isolated, negatively charge, or both. The positively-charged coating composition is sprayed onto the dielectric material. If the dielectric material is charged negatively, the process of the present invention further includes the step of maintaining at least a portion of the negative charge on the dielectric material while positively-charged coating particles are being sprayed thereon.
