Powder Coating for Non-Metal Products

2001

Dear finishing.com members,

We are engineers from a company that utilizes aluminium products.We are using an ELECTROSTATIC POWDER COATING SYSTEM . We would like to learn if we can use the same system for coating non-metal products; like wood, ceramics and composite panels.

Sincerely yours; Teoman Gulre

Electrostatic powder coating is used to coat materials as diverse as pottery and glass. It is already used to coat wood, or to be more precise MDF (Medium Density Fibreboard). However the powder coating used to coat wood or other heat sensitive products is UV cured and would require specialised equipment.

If you need any other info just let me know.

Hope this helps

Yes is is possible. There are several firms in the U.K. alone doing this. You do not need U.V. curing equipment. Ordinary thermo-setting type powders can be applied to M.D.F.

However the board needs to be pre-heated first to help it achieve an electrostatic charge. Also, it helps if the powder is low temperature, i.e. flows at about 140 °C.

The powder is then flowed in an oven. This is best achieved in an infrared oven.
