Applying dry conductive powder coating to screws and rubber-bonded washers is a common method used to improve their appearance, provide corrosion resistance, and enhance durability. Powder coating is a dry finishing process where fine powder is electrostatically applied to a metal surface and then cured at 200 temperature, creating a hard, protective, and visually appealing finish.

Here is how the process works for powder-coated screws and EPDM bonded washers:

Surface Preparation: Screws and EPDM bonded washers need to be thoroughly cleaned and pre-treated to remove any dirt, grease, or residues that may interfere with the adhesion of the powder coating.

Electrostatic Spraying: The powder coating is applied to the cleaned and pre-treated screws and conductive EPDM washers using an electrostatic spray gun. The gun imparts a positive charge to the powder particles, while the screws and the conductive rubber washers are either grounded or carry a negative charge. This electrostatic attraction ensures an even and consistent coverage on all surfaces.

Curing: After the powder is applied, the screws and conductive rubber-bonded washers are heated in an oven to cure the coating. The heat causes the powder particles to melt and fuse together, forming a continuous protective film.
