Abstract
Official abstract text for this publication.
Methods and systems for coating metal substrates are provided. The methods and systems include a powder coating composition comprising a polymeric binder and an application package. The application package includes at least one antistatic component and at least one post-blended component. Use of the application package reduces back ionization and faraday cage effects during electrostatic application. The described methods provide coatings with optimal surface smoothness and edge coverage.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for coating a substrate at one or more corners, comprising: providing a metal substrate; applying a first powder coating composition; applying a second powder coating composition over the previously applied non-gelled first coating composition, the second composition comprising: at least one polymeric binder resin; and an application package including an antistatic component; and a highly dispersed fumed metal oxide component with agglomeration particle size of 5 to 50 nm. 2. The method of claim 1 , wherein the application package comprises 0.1 to 2 wt % of a quaternary ammonium salt as an extrudable antistatic component; and 0.01 to 1 wt % of a fumed metal oxide as a post-blended highly dispersed component. 3. The method of claim 1 , wherein a cured film formed by the powder coating composition on a corner of the substrate has 20-degree gloss of at least 60. 4. The method of claim 1 , wherein a cured film formed by the powder coating composition on a corner of the substrate has 60-degree gloss of at least 60.
